Topic: Bug: NVOF limiting to 90fps when 4px and less than 3 CPU threads

When I set the motion vectors grid to 4px and use less than 3 CPU threads, SVP only goes to 90fps. 
This happens on different resolutions (480p, 720p, and 1080p). Likewise, my cpu and gpu are not showing any signs of being unable to keep up.
The problem disappears when I use 3 or more CPU threads. The bug appears regardless of using ffdshow, avisynth filter, or native avisynth.

At 8px and 1 CPU thread, I'm able to easily maintain 120fps without stressing my cpu or gpu.

Specs: i9-11900k, 3080ti, 32gb ram.
Software: Potplayer 1.7.2630, Windows 10 21H2.

Please let me know if there's anything else I can provide.

why?

obviously, with 4 px grid SVP need at least 3 CPU threads to go higher than 90 fps big_smile

Re: Bug: NVOF limiting to 90fps when 4px and less than 3 CPU threads

I'm using a capture card with video game consoles to add motion interpolation. So I'm trying to keep lag a low as possible.

Is it possible to use more CPU threads without increasing the framebuffer? Or to get SVP to work with 4 px grid and 1 CPU thread?
