Regarding post #80 above: There may be a difference with chart drawing performance between using OpenGL as compared to the GDI. But it does not matter how s_UseTool::AddAsUserDrawnDrawing is set when it comes to performance in OpenGL or the GDI. If there is a performance issue, we just need a chart with manually drawn drawings to demonstrate this. Not from ACSIL because we cannot reproduce what you are doing.

Re #80 & #101 - I can send you a chart, but it is easy to replicate. I manually add a number (say 20-30) of drawings such as 'extending rectangle' or 'rectangle' or 'horizontal ray'. As the count of drawings added increases, then when adding each new drawing (or modifying existing) the CPU & GPU usage increase significantly and as a consequence the UI becomes much less responsive.

version 2014 I can see that there are still problems with text readability, each written character is blurry compared to its equivalent in a Sierra Chart platform without OpenGL this happens in the Values Scale, Time Scale, Text Drawings, Chart Dom Quantities Some special character like «€» doesn't work with OpenGL https://i.imgur.com/KSoi8Zr.png

Regarding post #104 this is not something we can help with. If the text in OpenGL is not acceptable for you, do not use OpenGL. There is not going to be any further changes with this. Support for non-ASCII characters will come later. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Tested opengl today on new 9th gen Intel i7 system with Nvidia Geforce RTX 2060 GPU, as well as Intel 630 iGPU, SC v2007. Chart drawing times all went down significantly to 0-1ms, CPU and GPU usage show higher. But in actual use everything including chart updates, UI responsiveness, moving windows, etc is notably more jerky/slow/less usable. Non opengl setting restores normal responsive performance.

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

More info related to my post 98 above. If there is only 1 volume profile, the color will display correctly. If you have more than 1 volume profiles then one of them displays correctly & the rest are grey. Other studies using transparent drawing will behave the same.

New issue v2015/v2016 When adding a drawing tool such as rectangle, horizontal ray etc they disappear from view when the cursor is stationary.

V2015 (& v2017) OpenGL I cannot see the price retracement tool during the pull of the anchors. I click on an anchor and do not see the price retracement until the second point of selection. update..... The problem still exists in v2017 Date Time Of Last Edit: 2019-11-28 14:46:02

v2021 Flickering or disappearing of tools "during" the draw/use of the tool. I believe #110 and #111 are the same things

The "Cycle" tool is not visibly drawing with OpenGL. (latest version I checked is 2028)

Thank you, the invisibility and flickering while trying to draw with the tools are the most problematic in my opinion.

there is still an issue when more than 1 volume profile with transparency enabled is loaded onto a chart, the colours are all uniform black/dark instead of the chosen colours

Per Post #116, I find that transparent fill rectangle top/bottom can also show just dark gray instead of the chosen colors when using OpenGL. If one turns off OpenGL then the chosen colors reappear

many transparent studies are gray and sometimes I have such charts as attached (GPU: AMD 5700XT)

V2028 chart draw time from almost 50ms to 1ms, excellent. Dash-dot line draw type shows as solid line.

If you have more than 1 volume profiles then one of them displays correctly & the rest are grey. Other studies using transparent drawing will behave the same. We are looking into this. The problem with Chart Drawings not appearing or flickering during application is being looked into. We are very sorry about the delay with all of this.

Why doesn't the check in global graphics settings, other, use open GL - Stay checked after saving all and then shutting down SC and restarting?

Interesting finding: I need to move my GTX-1060 to test new trading PC so I install my AMD Radeon RX580 to the trading PC I've been using. This 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. This doesn't happen w/ the GTX-1060. RX580 driver is Adrenaline 2020 20.2.1 GTX1060 driver is 441.87

Has anyone attempted this running SC on Parallels - MacBook with MacBook connected to a BlackMagic eGPU Pro with an RX Vega 56?
