@RIFT. I've tried 2 x 1070gtx on windows 10 with 4 x 4k monitors and 2 x 1440p and it runs like a dog. I always thought this was more a limitation of windows than the GPU. Would love to be proven wrong as I have 6 monitors and only 4 are actually in use right now! Date Time Of Last Edit: 2021-02-16 20:32:18

I have 1 GTX 1060 Ti tunning 2 30 inch 4K monitors and it runs like a race car with OpenGL. I've never had an issue really. One thing I also did was to create sierra instances with the first instance being the highest priority charts where I want the best performance. that made it even better.

openGL with amd card is not on point. With a GTX 970 , i was never going over 50% gpu usage with all my setup open ( 20 to 30 charts with a lot of indicators. ) With the rx 570, I just scrool in a chart and i get 50% cpu usage. ( only 8 chart open and market is close. ) So , definitly , nvidia is the way to go here. Date Time Of Last Edit: 2021-02-16 23:08:42

Reported same AMD GPU issues mid-2020 in posts (see #185, #188). Hopefully this will be solved - finally. Thank you.

is anyone using this feature experiencing any real world advantages? I thought the "old" method was already very efficient, i didnt have any issues. Even with hundreds of charts, i tried the "hide and destroy chart obj" feature and the cpu usage barely budged (win7). I tested this feature a while back and i had a lot of issues with performance (running 4k screens), along with the gpu sucking up the battery and fans going nuts. Just curious if there's something im missing. Maybe there are particular drawing methods or visualizations that this offers significant improvements? edit: now that i think about it, there are a couple of graphic issue i had with the old method. One was drawing objects (like ext rectangles) with some transparency. The other was having lots and lots of graphic elements (like drawing zigzags on a large dataset). Is this what this feature is trying to address? Because the "core" graphic elements of drawing chart bars already seems optimized as far as i can tell. Date Time Of Last Edit: 2021-03-30 10:16:12

Hello. Problems with AMD 2400G VEGA APU. Issues rendering prices and time scales. Not working. If Sierra are going to be a full paid quality tool, with the "level of engineering" you state, it must support AMD graphic cards and drivers as soon as posible. Thanks

this is a well known problem with AMD. it's not SC specific. do a web search on "AMD OpenGL" and you'll find years of posts.

Flickering is the worst when I activate the crosshair or move the mouse over the chart trader and adjust region line. Date Time Of Last Edit: 2021-09-08 16:29:50

Personnaly , Thas is why I go with nvidia GPU now , a lot less problems , if they have any at all. Also, I realize that SC will max out my GPU , so i need a better one , I have a 1070ti. ( GPU will help you a lot in Refresh rate time for charts that you load with high intensity studies VBP etc. ) My 1070ti is loading well loaded chartbooks , 12 times over 16 instance and all that on 5, 4k tv. hope this can help.

We were not able to reproduce any flickering or any of the reported issues when using an AMD video card and OpenGL. The problems are not reproducible by us and we made a significant effort to reproduce: If Sierra are going to be a full paid quality tool, with the "level of engineering" you state, it must support AMD graphic cards and drivers as soon as posible.

I found that a lot of bugs just disappeared on my side when I did full reset of my pc with a fresh install of window 10 from a boot USB stick in bios. But still , I recommend NVDIA as driver issues is more on the side of the main compagny than the Software compagny. And NVDIA have the best driver support at the moment period. This is from all my testing ! Date Time Of Last Edit: 2021-09-11 16:54:26

I have since upgraded to an Nvidia based gfx card. Newer hardware:3060 ti (prev card was rx 580 circa 2017-18). OpenGL works a charm now. No flickering. Makes it usable on the DOM. The only drawback is fugly text. Alas.

At rift , nice to know that , I will not upgrade to win11 for now. I don't like Win 11 at all, there is definitely no way with SC, don't update to Win11. I like Winserver very much. Unfortunately there is no Winserver driver for my AMD GPU. It only worked with Wmware. I have activated the 3d calculations in Wmware. Date Time Of Last Edit: 2021-09-14 14:27:52

We were not able to reproduce any flickering or any of the reported issues when using an AMD video card and OpenGL. I removed all AMD drivers with the AMD cleanup utility. I swapped display port and PSU cables, I plugged the graphics card into another pci port. I have reinstalled Win10 and Win11. I've installed all sorts of enterprise drivers, not just adrenaline. I played with the radeon software for a long time, the flickering persists.

RIFT , at this point , its time to sell your AMD gpu and get a NVDIA one , Those problem are really hard to fix and for that reason I replace my AMD gpu for an NVDIA. NVDIA drivers are on point, and that is why NVIDIA are usually Pricier. My setup is 5 4k monitor with 12 instance of Sierra chart Plus multiple other program. I have change my video card from a AMD to an 1050 ti , then to a 1060 3gb ( was missing power and ram ) and then to a 1070 ti 8gb . because It really makes a difference when you have a lot of Studies to load. But now , I am thinking about getting a dual 1070 ti. ( one of my screen black out for a sec this morning , this was happening everyday with my 1060 + With more power I will be able to drop my Refresh rate more. ) hope this will help.

There are still many of us with AMD cards waiting for this to be fixed, but I have personally given up on this prospect. It's not so easy to just 'buy a new video card' these days unless you want to pay a small fortune.
