a common solution is to add the following hints to the primary executable, i.e. export these two:
Code: Select all
extern "C"
{
__declspec(dllexport) int NvOptimusEnablement = 1;
__declspec(dllexport) int AmdPowerXpressRequestHighPerformance = 1;
}
this will force to use a dedicated GPU when running the app.
that being said, I see no reason why integrated intel GPU would be unable to render something as simple as this
I'd guess that perhaps it has problems with multisampling or something else related to initial OpenGL setup (context?)

3D Chess System Tal fixed for users with two GPUs, available from the website above:
- Asset CST-GUI-2.07.1.zip — 199 MB, state uploaded
Feedback please, because I can't recreate exact 2-GPU systems that failed, but it should be working
Thank you very much for the GUI that now works fine on my laptop here. And for your very interesting engine that I use quite often.

Thanks, the CST-GUI is frozen for the moment, on a 'good enough' basis, while I do other things.
