I've selected NVENC HVEC as hardware acceleration, but the majority of my recordings (both regular and TimeShift) still end up being recorded with H.264/AVC. Only every now and then does a file appear to be truly encoded as H.265/HVEC.
Video settings are as follows:
- File format: MP4
- Video size: Original (Issue occurs with 1920x1080 and 1360x768, different screens that are swapped often. I will have a new, permanent monitor soon.)
- Video framerate: 60 fps VFR
- TimeShift: 4 minutes, output to 4GB RAM
- Video quality: Normal
- Bitrate (MP4): 100%
- Input range: 0-255
- Use multicore recording: enabled
