[Sticky] - OpenGL support Now Ready for Initial Testing

[2019-07-12 01:03:21]
Sierra Chart Engineering - Posts: 78023
Prerelease version 1947 of Sierra Chart has support for OpenGL:
https://en.wikipedia.org/wiki/OpenGL

The basic objective of OpenGL is to transfer the rendering of graphics from the CPU to the GPU to reduce CPU usage.

The greatest reduction in CPU usage is going to come from systems that have a capable and fast GPU:
https://en.wikipedia.org/wiki/Graphics_processing_unit

This option can be enabled through Global Settings >> Graphics Settings >> Other. Once you enable the option for OpenGL, a restart of Sierra Chart is needed and Sierra Chart stays in that mode until the option is disabled and is restarted again.

OpenGL support is very much a beta. There can be stability and rendering issues. For example, the Chart Values tool does not function properly. OpenGL does not have support for text so we had to create an alternative to do text. So text is not necessarily going to render in a way you might like.

Once again this is considered a beta and problems can be expected. We do not recommend using OpenGL during live trading.

Report any issues in this thread but we will not necessarily respond. There is no need to go into extensive detail. And if it issue has been reported, then do not report it again. We do not want to be flooded with all kinds of issues. And once again we will not necessarily respond.

If you are using Linux and you have problems, then please at this time do not post those issues here. Our first objective is to have stability on Windows.

Hi support, a few observations -

- Transparency is inverted for drawing tools and chart drawstyles - i.e. 100% = fully opaque and 0% = fully transparent

- Circle drawstyles produce very coarse polygons, rather then circles

- Chart drawing tools fill behaviour is inconsistent, both in color selection and whether the shape actually fills

- Chart drawing tools cause large CPU spike and are not very responsive

- When scrolling charts that have circle drawstyles, there is very noticeable screen tearing


Not all negative feedback though - render time for 'Market Depth Historical Chart' is massively reduced, which is great!

Yes the font look like pixelated bitmaps.
You can render nice clean TrueType fonts using FreeType which is popular on non-Windows systems.

yes, beta.
after 1 min of moving the mouse around the chartbook across the screens, with the opengl option enabled, all 3 screens went black.
unrecoverable. physical button need it to restart the system.
2 1st screens to internal gpu, the 3rd to secondary gpu.

When using Numbers Bars with "Highlight Volume/VPOC" or "Candle Stick Outline". There is a black box in the foreground. Regardless of the color settings.

Regarding post #4 and post #6 where the screens went black, can you provide us the following information:
1. What are the exact models of video cards, amount of monitors in the system, and screen resolutions?
2. What version of Windows is being used? Screenshot of system information would be good.
3. Does the issue appear with some specific chartbook(s)?
4. Can you download, install, and take screenshots from the tabs "Graphics card" and "Advanced" in software:
https://www.techpowerup.com/gpuz/
4.1 Can you take screenshots of the tab "Sensors" from GPU-Z when you run SC?

yes, sir, I can provide you with all that.

However, you might be quite right when saying that sounds like a driver problem, because my video driver crashes from time to time.

But, crashes, alters the resolution of 1 or 2 screens, and I can recover it, revert back the resolutions and continue normally.

The beta OpenGL option of your software seems to increase the problem, leaving the system unrecoverable. But the problem is there before the OpenGL option.

So, thank you very much for your efforts, but might be my system.

I've updated the drivers, even tried with previous versions, but same result.

If you still want that info, let me know... But I should have the driver problem fixed before being able to evaluate properly the OpenGL way (which is not gonna happen soon because I've tried everything I know already)

The system is a win server 2012 R2 and the secondary GPU is based on a ATI chipset. 2 of the 3 screens are UHD.


Thank you very much.

Hi. Just downloaded V 1951 to see the difference of OpenGL. Here's what I notice

1. No visible crosshair, even though it is enabled. It will appear for fraction of a second when moving mouse around.

2. None on the keyboard shortcuts work. I checked in global settings and they are the same as before, just don't work.

3. Tearing of price and time scales on all charts when moving mouse around. First img is the chart where I have pointer on ( tearing ) and second img is second chart ( tearing1 ), and it's even worse then the first one. I have Global Cursor on.

The visibility of the crosshair was always this troublesome. Even before the implementation of opengl. Couldnt find a solution in any of the crosshair related settings and there arent that many as far as i know.

@SC It would be nice if you could give us an always easy to find crosshair option...just thicker crosshair lines may work. Yes, there are workarounds like pressing CONTROL button on the keyboard in combination with the right mouse setting in windows. But its still not convinient or optimal.

I would like to have the crosshair as my default pointer because i could compare quickly a pricelevel in different timeframes. But not knowing where i am on the whole screen lets me always switch back to the default arrow pointer. The crosshair is just not visible enough or not visible at all.

I only brought this up because without OpenGL enabled I never had a crosshair problem. It is always visible and tracks time and price like it should on all charts. Sometimes it will disappear from one of the charts, but all I have to do is just move my mouse over to that chart and it comes back.

This is said in Post #1:
For example, the Chart Values tool does not function properly.

The crosshair is just not visible enough or not visible at all.
If you have a problem it is because you are not using the right settings based on the chart background color you are using and your screen resolution.

The visibility of the Chart Value/Crosshair tool has never been an issue. You can adjust the colors, the Line style and thickness. Refer to:

I HATE to capture this thread...sry, its about opengl and NOT crosshair.

But just to be on the same page: I am not talking about the horizontal and vertical lines extending to the edges of a chart window. I am only refering to the little cross in the center. My comment is kinda off-topic, i must admit.

Nevertheless, are we still talking about the same thing and i am able to even modify the center cross?

But that particular object is something you can control in the Pointer settings through the operating system control panel. It is not set by Sierra Chart. You should be able to choose a larger one and one with a greater contrast.

Changing the pointer color did the trick. The arrow mouse pointer is black now but the crosshair gets a white outline.
Its a compromise...thx.

I am assuming this problem is associated with this Beta software: Attached file shows:
1. The range of the rectangle fill is incomplete.
2. The ragged right edge of the rectangle fill.
3. The artifact of a semi-opaque vertical edge price scale, not fully vertical.

This is always reproducible.

A system information file is available at http://speccy.piriform.com/results/z5MmaP6NAn8kfe8ilHioyxA

Update: I turned off the OpenGL option, and was able to reproduce the problem. So this message is posted to the wrong thread. Sorry, haven't had this problem before.

You need to restart Sierra Chart after disabling the OpenGL option. If you still have the problem after restarting and not using OpenGL, then post that particular chart following these instructions but only if you are not using OpenGL:

I get a crosshair with OpenGL only when the chart is updating. So without datafeed there is no crosshair.

When using 'Study Subgraphs Reference with 'Transparent Fill Rectangle Top/Bottom' the fill occasionally works on a chart but mostly not. This might be the case for other transparent Draw styles and may not be limited to Study Subgraphs Reference but i've not tested them. Also, I think this may be related to CFD's as it works as expected with Futures. See attached chartbook

Also when using the 'Colour Bar based on Alert Condition' with 'Color Bar Hollow' draw style, the fill of the bar is always black even if there is a 'Color Bar Candle Fill' which is triggered

When different color transparencies overlap, sometimes the combined color is just one of the colours. For example when green and red overlap, instead of orange the color would be red or green

However what works fine is when same transparent colors overlap and they create a more opaque version of that color

Moving mouse marks somehow everything on the right, e.g. price of asset, values of indicators etc.

Click in chart region with crosshair, move mouse, -> marks the right of the screen, marks disappear with left click.

are there any known issue with nvidia cards, or optimus? Or some min spec for the graphics card? settings tweaks? Usage limits in terms of how many charts it can run?

I have an nvidia 1050m 2gb. Even with just one chart (sized at about 1080p) there's an unuable amount of lag when i'm forcing it to use the nvidia card. Oddly i see both the integrated intel and nvidia gpu usage spike when i'm doing anything to the chart (like scrolling around). When using the integrated intel card only, the system is more responsive, which is very odd. Could be a configuration thing but i have no idea what it would be.

Performance chokes pretty fast with additional charts. When I run 1 of my normal chartbooks (which as about 8 normal charts, 1 blank chart, 1 detached chart, all fitted on a 4k monitor) the intel card is maxed at 100% when idle. I'm usually running 27 of these chartbooks at a time, which runs great non-opengl.

All the settings in the nvidia control panel are set to off or optimized for performance

Just a Data Point....looks good here.

I have an AMD Ryzen 7 2700x processors and an Nvidia Geforce GTX 1660 Ti graphics card with two large monitors.
I have two chart books open and a large number of charts in each plus spreadsheets.


Without OpenGL processors utilization are:

CPU=3%
GPU=9-10% (very Stable)

With OpenGL utilizations are:

CPU = 3%
GPU = 10%-25% varying

Looks like work is successfully using GPU for rendering.

No issues noticed at all so far.

I did find one issue. The "Right Edge (centered) " Value label will not show when OpenGL is turned on in the studies in the lower chart regions. (version 1971).
The "centered" and "above" etc seems to be having issues also.

Works fine without OpenGL

Should OpenGL issues be posted here (like post 34)? Are the issues being logged for the developers? There are a few threads on OpenGL and one place to follow along with would be good. I'm very impressed with the performance BTW. The Chart update times have dropped over 10 fold on my computer. most charts say 1ms update, amazing.

Regarding post #30 above:
1. Screenshot of Sensors tab in GPU-Z app when the problem appears and first tab on idle.
2. Attached Chartbook. Perhaps there is some specific settings for studies/chart
3. how many displays do you have?

Also the user may try to reduce screen resolution to 1600x900 or even to 1280x720 to reduce usage of video RAM.
If you need help with GPU Z let us know.

Certain text isn't showing on screen. For instance, I cannot see the DOM quantities when Draw DOM Graph on Chart is enabled. I also cannot see the number box in bottom right hand corner that tells you bar spacing.

I am also getting laggy user interface when moving charts around or scaling charts using NVIDIA GTX 1060. I don't experience any of this when using the integrated Intel graphics card. The NVIDIA card gives much faster chart drawing times though.

latest opengl updates have worked nicely on chart drawings and transparencies mostly, but I'm getting some new issues after charts have been running for some time. Drawings or studies using transparency with set colours like blue/red etc, the colour changes to black and they are not clearly visible any longer. This happens on some charts in the chartbook, not sure if it only affects some charts or all

Also sometimes a chart will just go black completely and nothing is on it at all, just black background. No bars/text/anything. I'm using 1984

more details on #40 to help debugging: When the left coordinates are out of view for a certain duration, the color changed to black. Condensing the bars so the left coordinates becoming visible, the filled color changes back to the its original color.

Yes they are added incrementally . You should always be running the latest version if using OpenGL.

I've got 2 GPU's in my system, nvidia 980 GTX and an nvidia 1070 GTX. The default GPU is the 1070 which is about 1.3x more powerful than the 980. In the nvidia control panel I can select which GPU Sierra is assigned to for OpenGL and CUDA. If I leave it on the 1070 sierra runs great and the GPU load is about 33%. I tried to assign sierra to the 980 however (for CUDA and OpenGL) and it's unusable. The load on GPU varies every couple of seconds from 50-90% (in task manager) and makes the whole system sluggish (windows 10 latest). The difference in GPU load doesn't make sense as I would expect it to be around 50-60% max on the 980 given the difference in capabilities of the GPUs.

Not sure what's causing this. Maybe the 980 isn't supported yet or not optimised. Or maybe I'm not setting everything needed up to use the 980 correctly?

Are optimisations expected down the line? btw i'm running 1986

Our initial thought about those users who are noticing performance issues with a particular GPU is as follows:

Do not tell the operating system what GPU Sierra Chart should be using. It needs to make that decision itself.

And a particular chart must not be contained in more than one display. If two or more displays a chart is contained within are driven by different GPUs, you would create a situation where there are inefficiencies because the operating system has to start transferring resulting output between video adapters.

It is not efficient to have GPU do the rendering, and then have this output transferred to another display which uses a different GPU.

The above statements still have to be technically confirmed by us, and are just at this point only a logical conclusion.

------
When changing which GPU Sierra Chart is assigned to, you do need to restart Sierra Chart so there is a re-initialization of OpenGL on the Sierra Chart side.

Hi support,
Not a technical issue, more an observation when using openGL.

Personally I am now finding line width 1 to be not much use for anything other than solid lines.
The line is either bordering on being invisible (in the case of dotted line) or it's difficult to quickly distinguish between dashed, dash-dot & dash-dot-dot.

If don't know if other people see it the same, or maybe it's just me and I should invest in new glasses (or use wider lines).

I observed some other strange behavior today when there are different coloured transparent rectangles drawn onto the chart.

- Sometimes the fill colour of one or more rectangle will change depending on the chart scroll position.

- Very occasionally, when switching chartbooks there is sometimes a faint/ghost image showing parts of the previous chart within the transparent fill area of one or more rectangles on the new chart.

edit: in regard to the comment about ghost image, having seen this occur a couple more times I can't say with any certainty what the source of the ghost image is. It may be from the previous chartbook or it may be from one of the charts behind current one (but in the same chartbook).

Ok, chartbook attached as requested.

I also attached a couple of images as an example of what I saw earlier, although not the same chartbook.
The rectangles in the images are added by a custom study, but I was able re-create the issue with manually added drawings also.

Let me know if you want anything else.

A further comment regarding post #50 -
Subgraph lines, such as MA, will often appear as a solid line when the draw style is dash, dash-dot & dash-dot-dot and the chart bar spacing is small.
In the attached images, the MAs are set to show each of the line-styles listed previously in addition to dot.

Regarding capturing screen images -
'Edit >> Screen Images >> Save Chart to File' does not seem to capture the screen colors correctly.
'Edit >> Screen Images >> Copy Chart Image' does not seem to work any more, a message is returned when trying to paste into paint - "The information on the clipboard can't be inserted into paint"

Another observation, relating to OpenGL & the following option -

Global Settings -> General Setting -> General 4 -> Destroy Chart Windows When Hidden

If multiple chartbooks are open within the same instance and this option is not enabled, then I am noticing that the application can be much less responsive.

The sluggish behaviour coincides with Microsoft's DWM.exe spiking to 10-15% CPU usage (typically <= 1%)
There are no detached charts and SC is contained within a single monitor.
The OS is Win 7 Pro.

Maybe this is expected behaviour, in which case I will make sure to always enable "Destroy Chart Windows When Hidden".

In regards to post #60, if a chart is not visible, it should not receive a WM_PAINT message and not be drawn. We need to test this. If it is not receiving a WM_PAINT message and it is still causing a performance issue, we need to see if there is anything we can do from our side.

I am using n_ACSIL::s_LineUntilFutureIntersection & sc.AddLineUntilFutureIntersectionEx() to draw transparent extension zones.
When a study draws multiple zones using more than one colour, sometimes the colours get mixed up along the length of the extension zones.
The attached images show the issue, image 1 has openGL enabled, whilst image 2 does not.

Re the pixelated text, changing the font to consolas bold actually looks quite good and a lot clearer than Segoe with Open GL

The only issue with this is that then the text in the label column and region data line can appear microscopic

Re selecting a price to buy or sell at from the Chart DOM, there is currently no option in the graphics settings to adjust the colors that appear when placing your cursor in the buy or sell columns of the Chart DOM.
See attached screenshots - it would be good to be able to choose these colours to make it clear what price one was selecting and it would also be good if the price column could show the text of the price chosen for the buy or sell regardless of what the scale settings might be for the Chart DOM. This would increase user confidence when placing orders from the Chart DOM

You can see the order price at the top left of the chart. And the colors are adjustable with these color settings in Graphics Settings: Chart DOM Buy/Sell Column Lines. We will see about adding separate color settings though.

To clarify my post #75 I meant the color of the box (both the outline color and the highlight color) when the cursor is in the buy or sell column.

I don't think that box color is adjustable by the Chart DOM Buy/Sell Column Lines colors
[2019-10-10 04:01:48]
Sierra Chart Engineering - Posts: 78023
Yes we know what you mean. And that color is controlled by Chart DOM Buy/Sell Column Lines as the documentation expresses very clearly. Refer to:
https://www.sierrachart.com/index.php?page=doc/ChartTradingCustomizingGraphics.php

And there is only an outline color. No fill color.

Is there a way to see Chart update performance in terms of time to update. It "appears" that the OpenGL is updating on a time interval (like 1 second) versus price change or smaller interval verus Non-OpenGL updating. Non-OpenGL being much faster.

v2001

UI responsiveness when adding drawing tools seems inversely proportional to the number of existing user drawn tools.

Drawing tools added in ACSIL (when s_UseTool::AddAsUserDrawnDrawing = 0), do not seem to cause the same issue.

Performing a direct comparison of a chart with OpenGL disabled does not lead to the same behaviour.

I would gladly test this in my configuration which may be a bit unusual. I run Sierra inside Windows 7 on a Mac using Parallels Desktop. Unfortunately, PD does not universally support OGL so when I enable the OGL setting in SC, it is disabled again when I re-launch.

v2005 (although change may have occurred in an earlier version)

Performance seems degraded when using Market Depth Historical Graph, UI is less responsive and chart lags hugely when scrolling (also see large spike in GPU).
There is a marginal improvement when the chart is on monitor driven by primary GPU, rather than secondary GPU.

This behaviour is not observed using the same chartbook but with OpenGL disabled.

Performance of basic charts does however seem improved compared to earlier versions.

Edit:
Ok, so I maybe I am actually wrong in my previous statement.
I have tested this some more and it actually seems that performance difference between display on primary GPU and secondary GPU is huge, also it is not just charts with Market Depth Historical Graph.

Attached image is what I see in task manager when scrolling the chart with MDHG study applied, is this expected or is there a problem (either with my system or SC)?

Also I should add that this running under windows 10, v1903, build 18362.449 if that is of any relevance.

is this problem known ( the one shown in the image ) ? I am using SC, latest version ( 2007 but happened with older versions ), windows 10 and amd radeon gpu ( rx580 ).

as on the screenshot, when i move mouse above the DOM or when adding/moving tools, all the text becomes black boxes, for a few frames and then becomes text again.

We have released version 2008 of Sierra Chart, with some changes with OpenGL which may solve a problem that some users have with high GPU usage with multiple monitors and multiple GPU's in the system. Only one GPU will be used and usually the primary GPU.

v2008
Tested today, issue described in post #86 persists.
Maybe a marginal improvement in secondary GPU / monitor performance, but this seems at greater expense to primary GPU / monitor perfomance, which is noticeably degraded when compared to v2007.

The performance degredation is most apparent when dragging the value scale to scroll charts vertically.
I did not test MDHG, only a basic candlestick chart.

Referring to post #32 above and same equipment and configurations.

without OpenGL

7% CPU and 0% GPU


with OpenGL running

Version 2007 CPU has gone up to 8-8.5% % and Single GPU is approx 70-75%% after a minute or so. Note: The earlier version in post #32 was around 1984 if i recall...maybe sooner

Same (8.5% and 75%) for version 2008 (pre-release).


What is curious is that the CPU has also gone up with OpenGL running.


With some further experimentation....I found that the bulk of the GPU utilization is comping from the displaying of two TPO-Profiles I have in my chartbook.
Chart 1 has Day session and Evening Session enables (two profiles per day)
Chart 2 has only the day session enabled

I minimized Chart 1 that shows two profile periods per day (intraday and overnight periods) and the results with OPENGL running are
CPU 3-3.5% and 27-30% GPU

I minimized the Chart 1 and Chart 2 (one profile period, no overnight) with OPENGL running and the results are:
CPU 2-2.5% and 22-24% GPU - basically no TPO charts running

Both TPO profile charts open:
CPU 8.5% and 75% GPU


Next, I disabled the Evening Session in CHart 1. SO both charts are only day session. and being displayed;
CPU 4-4.5% and 30-35% GPU

Conclusions:

- The TPO profile charts are extremely GPU intensive and a simple TPO profile charts almost doubling the utilization of all other charts in chartbook (approximately 12 charts plus spreadsheet)
- TPO profile with just day session (no evening session) while adding a lot of utilization is far more reasonable that also enabling the evening session.


Maybe the TPO profile studies could be revisited to understand why the GPU utilization is so high especially with the evening session turned on when using OpenGL?

Without the TPO profile charts/studies.....the OPENGL utilization is quite reasonable.

Update: after setting for awhile the GPU is now 80-90 %...wonder if there is a leak....related to TPO charts?

P.S> I'm using 2 monitors which, with experimentation, have no effect on the GPU utilization in this experiment. also, note that the GPU utilization climbs slowly (a couple of minutes) to that 75% mark after bringing up a chartbook. I have an AMD Ryzen 7 2700x processors and an Nvidia Geforce GTX 1660 Ti graphics card with two large monitors.

Are the TPO Profiles displayed as Letters, Blocks or Horizontal Bars?

The greatest reduction in CPU usage is going to come from systems that have a capable and fast GPU:
We do not recommend using OpenGL during live trading.

Which would you recommend between consumer gaming vs professional/quadro for best suited to Sierracharts performance?

What's the expected timeframe for OpenGL to be be ready for live trading?

We do see poor performance with TPO charts when using OpenGL. We will be looking into this.

Thanks. For what's it's worth...without OpenGL enabled....I also see a difference in CPU utilization when the two TPO charts are minimized also. from 7% down to 5.5-6% on the CPU
