AMD or Intel support

[kode54]

Does this library support RT on anything beside NVidia RTX cards? I can't get it to work on Intel Arc under Proton.

I don't know about Intel Arc, but AMD RDNA2 support was implemented and enhanced in the following pull requests

• Fix ssbo binding count mismatch (AMD RDNA fix) #10 (Apr 8, 2022)
• AMD GPU support #11 (Apr 9, 2022)
• [AMD Fix] Insert a COMPUTE->FRAGMENT stage transition barrier before drawing the HUD #28 (Feb 28, 2023)

I have played prboom-plus-rt, which I understand uses RayTracedGL1, on my AMD Radeon RX 6700 XT (RDNA2).

I will test on Windows later, and probably close this issue as it will likely work there. Probably a Proton issue if it didn't wrap the Vulkan RT pipeline support properly.
