Change the last setting, "Duplicate frames removal" to "Do not remove" and try playing it.

I had a similar experience.

You're right! It significantly impacts the performance. I wonder why this option is even available, as it could easily confuse newcomers who might accidentally activate it.

I had a similar experience.

I don't know what to do here.

Fabian try to play around with the resize setting until it works for your system:

And please tell us at what value it plays smoothly for u

I'm using SVP with a license, and it works great for the most part, however I am having issues when choosing the RIFE AI profile. I have a NVIDIA GeForce RTX 3060 8GB. However I can't get this to work. Whenever I choose this profile, a command windows pops, and starts logging data, the video immediately freezes, after 5 minutes or so, it starts playing in 2-second chunks, then it freezes 1 second, and then plays another 2-second chuck. I don't know what to do here. This is a 1.3 GB MP4 file, it should be such a burden to reproduce.  I appreciate your advice.
