Topic: nVidia motion vectors grid setting of 4 px causes original frame rate

As the title says.

Using a 3080 and 9600k, so I can't see it being caused by hardware.

I tested videos of 720 through 2160p resolutions, and no matter what I try, 24p content looks like it's playing at 24fps. I've tried reinstalling to no avail.

Is this a known issue? If so, is there a planned fix?

Re: nVidia motion vectors grid setting of 4 px causes original frame rate

nvof_grid 4 px doesn't work properly even on my 5800X.

8 px is the lowest you can go with it working properly from what I've found. And it's definitely not a CPU limitation in my case.

Re: nVidia motion vectors grid setting of 4 px causes original frame rate

dunno, works with any video resolution for me (mobile rtx 2060)
however when playing 2160p the SVP index is low (0.8) and there're a lot of dropped frames in madVR

> causes original frame rate

any errors in SVP's log?

Yes, I can confirm my testing is all in 4K (2160p) these days. I do not consume any 1080p or 720p content anymore.

RTX 2070 Super for me, with a 5800X CPU.

The original poster is using an RTX 3080 too.

Re: nVidia motion vectors grid setting of 4 px causes original frame rate

"low index for 4k" is different from "videos of 720 through 2160p resolutions ... playing at 24fps"

if there's no errors in the log and SVP index is ~1.0 then it may indicate the old issue with 30xx series

edit %APPDATA%\SVP4\override.js
insert line:

smooth.nvof.cost = 0.7;

restart SVP
see if something changed; try different values below 1.0 - 0.8; 0.9.

No errors in the log, tried the change you recommended but same thing. Massive frame drops, even though GPU and CPU usage is low, and SVP index is ~1.0

I use 2070 Super, not even RTX 3000 series.

Check picture below (1 is dropped frames, 2 is GPU usage, 3 is svp index):

Only happens with 4 px by the way.
