Question / Help Laggy local recording

[Fenwick17]

Trying to do some local recording with overwatch, my in game FPS will be around 100, or I can even cap it to 60 however the final recording is laggy as hell both video and audio.

Update: When telling OBS to downscale to 720p its fine.
So what can I change to allow me to record at 1080p 60FPS

Your CPU appears to be choking. Use the recording quality presets under Settings > Output (Simple output mode) or read http://obsproject.com/forum/resourc...lity-recording-and-multiple-audio-tracks.221/ (Advanced output mode) and pick one of the hardware encoders.

I am currently using x264 with 20CRF and Very fast preset.
Should I use NVENC? Or would other changes be better?

Both QSV and NVENC should be fine.

NVENC at 15000 CBR seems to be working fine. Any major quality differences between the types?
Also do you know what would cause the CPU Bottleneck? Figured an i7 would be fine

Recording at 1080p60 and the veryfast preset is still a lot of encoding work, plus the CPU is running a game at the same time. 15000 Kbps is probably a bit low and I still suggest using the recording quality presets or the linked guide instead.

Apologies did not see the preset.
NVENC at 25000 and High quality preset and x264 at Ultrafast also seems to work fine.
Do you have a recommendation on which to use?

If you're using x264 or setting a bitrate you're not following the suggestions that have been made.

The bitrate was in regards to NVENC.
When using x264 I have CRF set at 20.

Edit: Altered NVENC to 20 CQP

Goodness. If you're in Simple output mode and using a recording quality preset you don't set a bitrate. If you're in Advanced output mode and following the guide that was linked you should be using CQP as your rate control method for NVENC and don't set a bitrate there either.

Sorted. cheers
