Hi, I've been experiencing issues in which my obs preview and recording are laggy. I have two 144hz monitors (idk if this even matters), a gtx 1080ti and amd ryzen 7 1700 processor. Not only does the preview show extreme lag, but the resolution seems to be terrible as well. I've tried everything, any solutions?
Question / Help Obs Preview And Overall Recording Laggy?
- Thread starter Auclairo
- Start date
Basics:
* Settings -> Video, make sure Canvas and Output resolution are what you want
* I recommend using NVENC as your Encoder in Settings -> Output (for both recording & streaming)
Past that, can't do much without a log.
1) Restart OBS
2) Start your stream/recording for at least 30 seconds (or however long it takes for the issue to happen). Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.
3) Stop your stream/recording.
4) Select Help > Log Files > Upload Current Log File. Copy the URL and paste it here.
(Note: If you do not see an obsproject.com URL, you will need to update OBS Studio to version 22+)

Some suggestions based on the log:
14:40:24.024: YUV mode: 709/Full
Change that to 709/Partial. You're incurring more load while decreasing quality for most users, whose displays do not support 709/Full.
https://obsproject.com/forum/resour...t-color-range-settings-guide-test-charts.442/
14:44:07.523: [jim-nvenc: 'recording_h264'] settings:
14:44:07.523: rate_control: VBR
14:44:07.523: bitrate: 40000
14:44:07.523: cqp: 15
For most cases with NVENC recording you want CQP rate control, not VBR.
14:44:07.523: lookahead: true
14:44:07.523: psycho_aq: true
These two features incur extra GPU load. You may wish to experiment with turning one or both off, especially lookahead when recording high motion content.
However, bottom line is that 144Hz does not pulldown easily to 60fps, which will introduce judder. In addition, in Windows 10 using displays with different refresh rates can also cause stutter. The only known workaround is to set all displays to the same refresh rate. If you're trying to record or stream 60fps, you're better off using 120 as a refresh rate instead of 144.

I proceeded to change the recording settings to VBR, with the said bitrate and cqp level. In addition, I experimented turning both look ahead and psycho_aq off (or one). Both my displays are set to the same refresh rate (Tried 120 hz) instead. Still jittering and looks like my game is running at 30 fps.

Just to be clear: what rate control method you choose selects what ratings control quality. With CQP selected, the quality setting determines the rate, and the bitrate setting is ignored. With VBR/CBR selected, the bitrate is chosen and the quality setting is ignored.
The session in your log is only 30 seconds in length, but there's no reported dropped frames in it. This may indicate that OBS is working normally, but that the GPU load it is causing is reducing the game's performance. 1080p60 in single PC setups can sometimes be challenging.
In any case, the preferred method of capture for games is game capture. Display capture is less performant.

Sorry, I just realized that you were quoting what settings I was using before hand with the control quality. I recorded some of my game using game capture instead of display capture, still running into the same issues. (keep in mind although i didn't implement all of the settings that you said, I had already tried and received the same result).

Sorry for the spam, but in addition if you would like to see footage of what my recording WAS like before this issue began to occur, feel free to (this recording is not straight off when I WAS playing, but recorded using a replay system inside of the game). https://www.youtube.com/watch?v=qZ9VhUEzbEM

The issue is that RB6 is problematic in single PC setups.
16:38:11.711: Game Mode: Off
Try turning that on. It was broken in earlier Windows builds but is fixed now.
17:01:56.937: lookahead: true
17:01:56.937: psycho_aq: true
These incur extra GPU load. Lookahead in particular not appropriate with high motion content like FPS games.
Not seeing frame drop in the log but if OBS performance is causing the game to lag, the usual solutions are in-game frame cap, fidelity reductions, or retargeting to 720p60 or 1080p30 or 900p60.

I would like to clarify that OBS is not making my game lag as all, the problem is that the actual RECORDING is laggy on the preview, along with when I actually record the footage (same goes with streaming as well). However, I can run the game fine at 144+ frames constantly (The footage doesn't look like my game at all).

Recording 60fps while running 144 refresh rate will always cause judder.
OBS is not dropping any frames, (at least not within your 30 second test in the log) so it appears as if it is recording what it is receiving.
For a test, you can try switching to simple output mode, indistinguishable quality, and large file size and see if that looks differently than what you are currently getting.
