I also confirm that for RIFE v2 4K video looks like a pixel grid. v1 doesn't have this problem.

Just in case, I found the reason for the driver hanging. My GPU undervolting settings were not suitable for such a load. There were no problems at all in games, but when using RIFE, the driver started to fail.

I thought you might be running out of memory, but I'm running on a 3080 with 4GB less memory than the 3060. How many GPU threads are you using? With 8GB I've found that any more than 1 GPU thread takes up too much processing and memory. I assume that you are using the TensorRT engine? Also using rife v2 took my GPU processing below 90% while also removing the seek delays I had with rife.

I use 4 GPU threads. If I use only one, then my system starts to slow down. With 4 everything works smoothly. At the same time, I carefully monitor the GPU memory and the load on the GPU chip. No more than 1.5GB VRAM is used at 11-14% GPU load for 1080p video. The model version is 4.6 (v1). "rife_trt_boost" is enabled. According to monitoring data, GPU memory usage and load on it is not a problem. Of course I use TensorRT, but for example, when the MPV player is running, this warning is displayed:

vstrt: TensorRT version mismatch, built with 2135 but loaded with 2136; continue but fingers crossed...

I used v1 version models that come as part of SVP. I also tried the 4.4 model, tried to turn off the boost, but still after a while the video driver crashes.

Display driver nvlddmkm stopped responding and has successfully recovered.

Tried this new feature. I really liked the quality. Even on my not-so-new PC with RTX3060, it works in realtime with 1080 video. But I have a problem. After 30-60 minutes, the video driver freezes with the following events:

The description for Event ID 0 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

I tried different versions of video drivers, tried different players (MPV, MPC-HC, MPC-BE), the result is the same everywhere - it works well, but after a while it crashes.
