Generation much slower on Linux than on Windows

[Serallan]

Hi! Is there anything I should pay attention to when installing and running A1111 on Linux?

I installed the GPU, CUDA, A1111 on Linux and it runs without errors, but I'm seeing dramatically lower speeds than on Windows on the same machine. The same generation done at 3s/it, 3min total runs at 30s/it, 30min on the Linux install.

My system also has an iGPU but it's running on the Nvidia GPU by default and the automatic launcher won't even allow me to try to select another GPU id, so I think it's running on the correct card.

My Windows install uses a previous A1111 version, plus different GPU driver and CUDA versions. Do you think the performance drop is down to the versions differences alone? Or there's something wrong with my install or OS config, some common mistake I should try to fix before trying different versions combinations? Any tips on how to debug that?
