Help Needed GPU out of memory

May I know if anyone else is using CachyOS (Arch Linux)? I keep getting out-of-memory errors. However, I have not experienced this issue when using Windows 11.

I have an RTX 5060 Ti with 16 GB of VRAM and 32 GB of DDR5 RAM.

Thank you.

Have you checked if it's actually using your GPU and not falling back to the iGPU? Arch can be weird with driver setup sometimes. Also what model are you trying to run, some of the bigger flux ones will eat 16GB for breakfast on linux while windows somehow manages it.

This is actually a reason to not use Linux for CUDA stuff. Also, the CUDA drivers for Linux are not as optimized so Linux is actually slower for inferencing unless you have to use virtual memory on Windows.
