Quote Board Performance

Hi there, apologies if this is a basic issue but I cannot find any other reference to it. When I have the Quote Board maximized to fill an entire screen (multi monitor setup) it causes the cursor to 'stick' when moving it around over charts on a different monitor. If I reduce the size of the QB to say half a monitor, the issue goes away as it does if I completely minimize the QB.

CPU usage is not high when this happens but I assume it is a graphics/processing issue on my PC rather than a problem with SC; see specs below.

Processor  Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz
Installed RAM  16.0 GB (15.9 GB usable)
System type  64-bit operating system, x64-based processor
Edition  Windows 10 Home
Version  20H2
Installed on  ‎30-‎Mar-‎21
OS build  19042.1052
Graphics Card: Geoforce RTX 270 with Max-Q Design

The reason I have the QB open on a full monitor is I add comments under field 'Comment 1' for each Symbol I monitor; sort of a journal feature.

Many thanks.

First thing we want you to do is to disable sorting on the Quote Board:

The Quote Board display is very efficient so really we would be surprised about this issue. The other thing to do is to check the update interval and increase it:

The 'sort' disabling does not improve it however, the update interval does. It was set to update every 1000 ms, I have changed to 10,000. However, note that every time it updates the cursor is 'sticky' again. Obviously with the longer update interval it happens less frequently but it is still noticeable each time it updates if I happen to be moving the cursor/something else elsewhere.

There is also a noticeable increase in CPU load, albeit still a low headline number (well below 15% for SC, which typically runs at <10%).

We definitely think this is a system specific issue. You should not have any performance issues whatsoever with the Quote Board. The implementation of that is very very high performance.

I've done some tinkering and the issue seems to be related to the 'crosshairs' being enabled. When enabled (Global Cursor is off) POWER USAGE in Windows Task Manager goes to 'Very high' and CPU jumps by 10%+. This does not happen when I disable the crosshairs and use the 'pointer' cursor instead.

Not sure how this relates to the Quote Board but it is only slightly worse when the QB is maximized; when the QB is minimized POWER USAGE still jumps when using the crosshairs, but not quite as much, so I believe it is the crosshairs causing the issue rather than the QB.

The Chart Values tool, which you are referring to, has had performance improvements implemented about two years ago and it is efficient. So not sure what the problem is. Are you using the OpenGL option do you know?

Not using Open GL, although just tried it. Didn't fix the issue and higher CPU usage.

I've reduced the amount of columns in the QB and made things a bit more efficient, so it's not a major issue, but perhaps something will come up in future.
