OpenGL issue when ploting subgraphs

So I made my first custom study, it was calculating the delta per price and then protting a subgraph on the chart when ever Delta exceeds threshold. And it finally worked but because there was too many subgraphs on the chart it lagged when scrolling. Due to that I found out that turning ON OpenGl will use GPU instead of CPU to increase perfomance. But after I turned it on my study subgraphs did not appear on the chart. I am using the sc.Subgraph[sgIndex].DrawStyle = DRAWSTYLE_POINT; and yes I restarted sierra. Date Time Of Last Edit: 2026-03-25 19:23:20

We are not seeing any issues with a Point draw style and OpenGL. If you try a different style (such as Line or Bar) does that work correctly for you? Also, we have had a few reports of the latest drivers for NVIDIA having a problem with OpenGL, such that it was crashing the system. We have not had the exact report of what you are stating, but it is something to check on. If you have an NVIDIA graphics card, and if you are on the latest driver, then roll back a few versions and see if this makes any difference.
