Question / Help Preview windows and recordings are choppy

[arc111111]

I have a decent PC, but I noticed that when I'm recording, streaming, or just testing my stream, the preview window on OBS is choppy. I've set my FPS to 30, but every seconds there's a mini-freeze. At first I though it was only on the preview window, but it does it on stream and in recording too. It's makes them really painfull to watch when everything stop and jump foward constantly.

I've tested many settings, but it looks like none of them are changing anything, even changing my FPS to 60 doesn't fixes it.

here's my log file. Anyone can help me out?

I'm not sure on this so don't take my reply as the only opinion but i'm thinking that your old CPU and GPU (while still enough to game) does not have the supported libraries or enough speed to stream.

Your bitrate and buffer speed are quite low. If that's the highest you can go with a slow connection you may not be able to stream anything with viewable quality. Do you get a red message at the bottom of OBS saying "taking too long to encode/skipping frames" by any chance?

Nope. I have a slow-ass internet connexion, but I can stream some games just fine (usually 2D games or games that doesn't involve a lot of movements or green colors).

Weird, It only does it on OBS, not xsplit. And I honestly don't want to go back on Xsplit because it's really slow and a pain to use.

EDIT: I figured it out guys, apparently if I use "game capture", I shouldn't play game on fullscreen. I switched to windowed and it's all smooth now.

Kind of a bummer because windowed is a lot smaller, but I'll live with it.
