Question / Help FPS in game fine but on OBS recording review dropping

[LastWitcher117]

First my log file: https://obsproject.com/logs/fAjTluvyEfb_XYqR

I had 2 1920x1080 60hz monitors and I could record easily but since I bought new 2540x1440 monitor I can't record anything with OBS, first of all in game I have a lot of fps in games but still there are some strange lags while obs is open (when i close obs everything is smooth) then when I start to record in game fps are fine but on OBS in the right down corner it shows that they are dropping to 23-34fps and so is my recording after this.....I've tried a lot of things can someone finally help me??? :)


EDIT: I disabled preview in obs and those lags in game have gone but still recording droping frames....

The extra load of the larger display is putting you over budget both for GPU rendering and encoding.

15:09:54.163: - source: 'Przechwytywanie ekranu' (monitor_capture)
15:09:54.163: - source: 'Przechwytywanie gry' (game_capture)

Game and display captures should be kept in separate scenes; they can interfere with one another and degrade performance.

Rendering lag due to GPU overload.

Encoder lag due to encoder overload.

You may wish to reduce your canvas resolution slightly, perhaps as far as to match your output resolution. This will reduce both rendering and encoding load. Either that, or drop to 30fps.
