Multiple GPU error

[shaqualeek]

Hi,
I have 2 GPUs on win 10 - an old GTX 970 and a new RTX 3060. I was hoping that the DXR version would work, but it crashes immediately after starting. Is there any way I could define it uses only RTX?

Regards,
Petr

I think the problem is that your GTX 970 is the default GPU and ArmorPaint always selects this one. You could probably make it run by selecting the default gpu for ArmorPaint. You can do that in your NVIDIA control panel or directly in the Windows system settings.

@luboslenco For example on DX11 kinc_g4_internal_init sets the first parameter of D3D11CreateDevice to NULL and thus the first (default gpu) is set. Maybe there could be an option to select other graphics cards, that could be useful especially on laptops. I'm unsure how to set it though because the config files are read after the graphics device is initialized.

Thank you for your answer. That's the whole point of keeping my old GPU - I want it to be primary and reserved for the OS.

You can also set it per application. That should do want you want to do.

I tried this, but it still won't work :(

ArmorPaintDXR uses Direct3D12 instead of OpenGL for rendering, any change there is a dedicated setting for that as well?
