I didn’t use RIFE because it was unstable with my overclocked 4090 HOF @3060 1.1V 666W. When processing 1080p@120fps content, the video would freeze after one to three hours, while the audio kept playing. 4K 120fps video plays back without any issues when RIFE isn’t being used, and the graphics card is perfectly stable in all kinds of stress 3D tests and games. However, it turned out that once I reset the clock speeds, RIFE became stable—even with 720p/1080p 120fps content.
It’s funny that this is the only application that can behave unstably, even when the graphics card’s temperature is low (a maximum of 50 °C, thanks to liquid cooling).
