Question / Help Can't record 60 fps with NVENC codec.

techdawg667 · Nov 2, 2014

Hello. I have a problem where I can't record 60 fps video with NVENC enabled. I can record 1080p 60fps with x264, and 1080p 30fps with NVENC, but once i bump the fps to 60, NVENC just records the first second of gameplay (very shittily I might add) and then freezes the video. I have a GTX 780 on the latest stable drivers.

Also, I am recording, not streaming, if that matters.

Example vid of what I mean: https://www.youtube.com/watch?v=u4SMcCCYhcU&feature=youtu.be

Here is the log:

Change the NVENC preset, llhq is pretty demanding compared to other ones.

Thanks switching from Automatic to High Performance preset fixed it.

Question / Help Can't record 60 fps with NVENC codec.
