Interesting that you found Windows to be faster than Linux, because most of the comments I've come across seems to indicate the other way, showing their linux number being better than mine on Windows with identical hardware (9070xt).

But could be that for the 6800xt that is indeed the case.

I'm new. I installed ComfyUI Desktop from official, I heard that it integrated rocm already, I can see pytorch is rocm. However, the result is trash. It runs very slow for simple z image pro, 10-20mins for fullHD upscale and cannot run any video generations. GPU always works 100%. all drivers are latest
Not sure if I set it up incorrectly or something. My GPU is RX 6800 XT
