I can see my RX 7900 XTX GPU in all pre-builds I download from Blender.org. However, when I try to build Blender myself (in Debug mode). I cannot see my GPU. I selected WITH_CYCLES_HIP_BIANRIES to “on” before I generated the project and before I built the project. I can’t find any information on troubleshooting this. I looked at this page:
Building Blender/GPU Binaries - Blender Developer Wiki
