When watching some 1080p/24fps films I still have slowdowns in some fast/complex scenes, it is always present when watching again the same scene.
It should not be related to hardware performance (3080Ti with only about 40% usage) and when the slowndown occure the load on the GPU decrease.
I think the RIFE filter just stop making interpolation for a few seconds that's why it can be perceived as a slowdown.
I tried to change the GPU threads number, from 2 to 4 but I see no change.
Do you have the same problem?
Is SVP going to update to the last release?

I also have the same problem when transcoding anime from 24fps to 72fps, there are slowdowns in fast or complex scenes.
There are also artifacts on vertical bars (eg. gates or fences) when the camera is moving horizontally. I wonder what causes that.
