If it is showing 1 CPU on default, go to settings, click on default group, and put the slider to 0 (zero).anonymous defaulteam wrote: ↑Fri Dec 26, 2025 11:10 pmMildly interesting observation; after splitting cpu and gpu into different resource groups, the info page of GPU WUs show them using 0 CPUs while on default group it showed them using 1. I assume it still uses the one logical cpu core per gpu.
It must show zero CPUs in every group, except CPU related group.
User must not assign CPU cores manually to the GPUs. User must just leave free cores for the GPU. Free means unused by anything FAH related.
So if a user has 16 CPU threads and 1 GPU on the PC, CPU group should have the slider set to 14 or 15, leaving 1-2 threads free for the GPU to use. GPU group should have the slider set to zero.
If user has 16 CPU threads and 2 GPUs on that system, CPU group should have slider set at 12 or 14 (leaving 2-4 threads free for the GPUs), while both GPU groups must have sliders set to zero.
The reason I mention 1-2 and 2-4 threads left for GPU is that some might argue that 1 virtual thread per GPU might not be enough, and performance hit might be significant, so 1 real core (2 threads) could be better. This is on AMD, more than nVidia, since nvidia users just don't fold on CPUs, as it takes away performance from GPU.
