my GPU tasks have started to freeze they are still technically running but my GPU is at less than 5% usage and that percentage completed is barely increasing at all I have an RTX 2080 super with a Ryzen 5 5600X on windows 11 it seems that in some periods in the work unit the GPU is being used but it goes though phases of 0-5% usage with random spikes

We're aware of some issues with Windows 11 performance when using nvidia GPUs.

We don't have any windows 11 systems to test against at the moment, and given the known issues with the windows 11 scheduler and Ryzen (MS really screwed it up), and the extremely complex nature of nvidia cuda and how it interacts with the host operating system, I'm inclined to wait until NVidia and AMD get some time to clean up MS's mess first, before we start looking at things we can do on our side, since there's really not much we do other than make calls for pytorch to use the GPU instead of the CPU (this is not hand-tuned cuda).

I know it's not a satisfying answer, but given that we haven't even released an updated v0.90 GPU client for windows yet (It's coming, was trying to get the linux version out first, but that's giving me more issues than planned), figuring out windows 11 performance issues are low on the priority list.

would it be better if I ran it on linux instead of windows 11?

I’d say that’s definitely a better choice than win11 atm
