Problem description

FreeCAD weekly builds conda Windows version doesn't use GPU in Windows.
In Task Manager, I confirmed that GPU is not being used, only the CPU is being used.
So, FPS is very slow in FreeCAD weekly release. For reference, it's normal on Ubuntu.

Anything else?

No response

Is there something we can do about it? Isn't that an issue with either your GPU driver or the way your desktop is configured?

GPU is being used normally in the following realthunder release.
FreeCAD-asm3-Daily-Win-Conda-Py3.10-20230131-x86_64.7z
FreeCAD-asm3-Daily-Win64-LibPack-Py3.8-20230131.7z

In FreeCAD-0.21.0dev-32552-Installer.exe, GPU is being used, but it's not fully used.

I renamed bin/opengl32sw.dll to bin/opengl32.dll due to black screen problem.

But, I got to know that opengl32sw.dll is for software rendering. So, GPU is not being used.

If I didn't rename it, the error message with black screen is below.

The black screen problem happens with old HD5500 iGPU.
I hope it works for the iGPU also.

Then not using the GPU is expected, I will close this issue since the black screen problem is something separate so it should go to it's own issue (although I don't think there's anything we can do about it since it's a driver problem)
