his is what I have found w/ respect to OpenGL, besides all other things have reported here before: Moving cursor on RX580 will render all text background to the same text foreground color until cursor stops.

is it the same I posted on #87 ?

We have released version 2045 with a resolution to the Open GL problems reported.

I do not believe 2045 solves the problem with transparent fill described above

Version 2045 did not resolve the issue with transparency. That has still yet to be done. It only resolved the issue with Chart Drawing tools.

Nice 2045 resolves the flickering when drawing. Thanks!

This isn't sticky anymore. Does that mean it's no longer a sore thumb sticking out because SC has no resource to support or it's just a plainly oversight mistake?

Well the thread is just very long and the OpenGL development is considered complete other than this transparency issue. And also some performance improvements we are working on.

Thanks

I think there's a lot of us waiting on the transparency issue as once that's solved there is a massive reduction in CPU usage going to OpenGL

For me, my CPU would go from 5% to 1% for my main chartbook

Greetings,

could it be that OpenGL usage needs alot more system Ram.
I dont use OpenGL because my PC is running out of its 16GB RAM.

Re: chart drawings vs. UI performance degradation

80 OpenGL support Now Ready for Initial Testing | Post: 195152
102 OpenGL support Now Ready for Initial Testing | Post: 198080

This issue still persists in v2048.
Once the chart area becomes more complicated (either by multiple drawing tools or subgraphs) the GPU is regularly saturated during UI interaction such as scrolling, drawing or moving the 'Chart Values Tool' crosshair.

In addition to the above, chartbooks containing multiple charts can cause the GPU usage to be consistently high, despite only one chart being visible.

I guess this means my that current GPUs are not sufficient for using SC with openGL in any meaningful way.

Can you make any recommendations for GPU specification?

Post #134....I don't know about recommendations, however,

I'm using an "NVIDIA GeForce GTX 1660 Ti" graphics card and it works great

As one example

Thanks for the info, I will have a look.

The latest version fixes the transparency bugs with OpenGL. I would love to use OpenGL for live version as the load on one core gets minimzed a lot and transfered to the GPU (especially noticable on a MDH chart). But the implementation still has some graphic issues that doesn't make it anywhere near visually pleasing.

- Fonts
- Lines (stair step on close)
- Overlays
- Volume bars

I attached some examples and how it looks when OpenGL is not used.

This is great, thank you.

One question for the SC developers: GDI objects from a custom study (rectangles in this case) aren't displayed when using OpenGL. Is this to be expected or perhaps a graphics card issue? Thanks

Using SC 2057.

Edit: For clarification, the 'GDIExample.cpp' also doesn't print to a fresh chartbook after a restart of SC.

For info, tried out Open GL on v2054 with one instance of my Trading chartbook running with following results
Open GL inactive CPU = 3.0 % Mem = 23.5 GPU = 0
Open GL active CPU = 0.9% Mem = 106 GPU = 80
With open GL active cursor movement became very slugish.
Graphics cards are 2GB PNY QUADRO NVS 510 DisPort, I guess these are not up to handling the load from Open GL.
As CPU never becomes overloaded I have de-activated open GL.

Using the GDI is not supported in a chart when using OpenGL.

In regards to post #142, you need to run 2056 for the latest performance improvements with OpenGL. Update and test again.

In SC 2014 I found that a Study Draw Style Line, Line Style Dot, Size 1 looks like a normal Line at zoom 0, I can see the dots only increasing the zoom. Please look at the following screenshots

http://www.sierrachart.com/image.php?Image=1574505608700.png

http://www.sierrachart.com/image.php?Image=1574505648177.png

It seems that zoom applies also to dots, it should not as per the not-OpenGL SC

thanks

it still happens in 2057

In regards to post #144 there cannot be any further improvement with that. We have previously said that.

Updated to 2057 with no apparent change in values that appear in Task Manager.
All I can say is that when Open GL is activated the reported GPU value is increased from a steady 0% to a number fluctuating between 20% and 80%. My knowledge regarding computer hardware is too limited to know the significance of this.
The CPU values are reduced as reported in #142.
Also noticed that some text created with Drawing Tool appeared in normal font whereas bold font is specified in the study. Changing Global Font from Tahoma to Arial rectified this situation.

Anyone has segmentation fault drawing on OpenGL or it's just me? It only happens during very fast market many times. My version is 2057. It didn't happen in version 2054. I can live w/ transparent issue but definitely cannot w/ segmentation fault. I'm back to non OpenGL.

Regarding the segmentation fault we would like to see if anyone else is encountering this before we invest more time in it.

I'm using a Quadro Pro P2000 card and have OpenGL turned on.

I've been experiencing SC crashing lately with OpenGL on. Let me know if there is a crash report anywhere else that might be useful in diagnosing the issue.

Here is the Windows 10 Event Viewer error message:
