Hi,

I wish to stream GTA 5 on Twitch. I have finally finished adding everything I want into the sources, and I am ready to start streaming. However, despite me getting very high FPS in game, OBS can only muster ~18 to ~23 FPS, as the FPS indicator on the bottom right reads. I would think that even that would be smooth, however it is not. The stream is pretty choppy in the preview, it looks like it's lagging. And, of course, when I do a test stream, the choppiness carries on to the stream. I have tried literally all recommended stuff to no avail and I am pretty frustrated, so if anybody could help, it would be appreciated!

(Specs and log file for one of my test streams included below. I run OBS on my second monitor to see the preview whilst I am streaming, btw.)

Any help would be much appreciated! Thank you in advance!

P.S My friend, who has a a slightly worse set up than me, can stream the game at 720p 60 FPS with out a single issue, and the stream is super crisp, so I assume it must be a settings issue?
