encoding stalls a bit, but then starts, and constantly works, no pauses.
Using a Geforce RX 4800 (with 560.81 Studio drivers): VRAM usage ~10,8GB (video decode is running at ~70.90% and 3D usage is at ~90-95%)
Since I can't see the settings and you didn't post them:
What does the Vapoursynth script look like?
(side note: not enabling 'Scene change' is usually a mistake, unless your whole clip is just once scene)
What GPU are you using?
How is the CPU and GPU (VRAM/3D/Decode) usage?
What drivers are you using?
Is a virus scanner running in the background? (aside from Windows defender?)
Any hardware tuning tools running in the background?
How are the CPU and GPU temperatures?
(for me GPU is ~45-55°C and CPU is clocked at 5.27GHz and at ~70-72°C)
What is your RAM usage? (mine is 18-18.7GB running the above script and NVEncC as encoder)
=> not having any issues here
Wild guess is that something is interfering or bottlenecking the decoding.
Looking over at
https://github.com/styler00dollar/Vapour...cnn-Vulkan I see no changes in the past 6 months that should influence the speed.
This does not look like an issue with the rife filter itself, but either your system or your other settings.

Ps.: rife-app (
https://grisk.itch.io/rife-app) is something different from Hybrid.
