What settings I can use to speed up the process?

[abrahamford2]

(Noob here) What settings do you recommend for me to speed up the process using just a GFPGAN (and sometimes just a mask)? Most of the things i'm playing with are very short videos and with no high quality/resolution, so I don't need big results. Lik,e does the codec, format, quality matters? if so, which settings can i pick to speed things up?

hi, in the settings tab, you may lower the Max Number of threads to 1. Regarding Masking, Xseg is way faster than Clip2Seg.

Hi. Why does lowering the threads lead to speeding up? This is counterintuitive, as threads are used for parallelizing the task.

As far as I can tell, increasing threads uses more VRAM. It does generally increase performance, but by only a bit, until VRAM is exhausted. When that happens, performance tanks. Therefore, lowering threads helps a lot in VRAM constrained scenarios (low VRAM, hi res, post processing, etc.) as 1 thread with all assets in VRAM is WAY faster than 2 threads that are swapping to system RAM.

I've also noticed the NVIDIA driver will swap VRAM to system RAM before the VRAM is exhausted which also tanks performance. That can be disabled in the latest drivers "Prefer no sysmen fallback" is the option, but it may cause crashes if you do actually run out of VRAM.
