Question / Help Local Recordings for game play are not smooth

[Lehsyrus]

Hello all, I am new to recording gameplay, and have been trying to get OBS Studio to work for a few days now, and can't seem to figure out this issue.

I am trying to record at 1080p 60fps, ingame everything is smooth as normal (typically CS:GO), however when I playback the recordings it looks choppy, almost as if the fps is significantly lower than what I am recording it as. The quality also seems diminished no matter what settings I use. I've tried x264, AMD HEVC x264 and x265. I've also tried tinkering with the bitrate from 3000 to 60000. Lastly, I have it running as administrator, have tried compatibility with Windows 7, and tried changing the priority to High and Realtime. I'm stumped at this point.

My rig is as follows:
CPU: i7-6700k
GPU: RX580
Mobo: Z170x-UD5
RAM: 16Gb G.Skill Ripjaw

Thank you for your assistance

If you're just recording, you have 2 options:

1) x264 encoder, "CRF" rate control set somewhere between 16-23 (lower values= better quality but larger filesizes) and keyframe interval set at 0;

2) H264 encoder, "Indistinguishable" preset, "Balanced" Quality Preset. This is the simplest solution, as far as hardware encoding goes.

If you get any rendering lag, I recommend using Radeon Chill as a FPS limiter, as you will get no input lag compared to other ways of limiting FPS.

For clarification, when recording, you should aim for a fixed quality setting, not fixed bitrate, as the latter (usually) only applies to streaming services due to their cap on max bitrate.

Thanks for the reply. Your suggestion on changing CRF helped a bit with the choppiness, now it just looks like the textures smear a bit when turning the player/camera. It almost looks similar to motion blur. I've uploaded a video to vimeo: https://vimeo.com/353503245. The quality is diminished from vimeo's compression but you can still see the weird smudged look that appears when i turn in game. It's easiest to see when looking at the player models.
