Question / Help No Constant FPS Possible ?

So i've been playing around with my settings quite a while and still i couldnt find any reason why i can't get a constant fps output on my stream. I don't frop any frames at all but still the fps in OBS randomly drops to 35 from 40 set fps, which causes lags. At first i thought it would help to turn of Mulitthread Optimization but apperently it didnt. I really don't know what causes this issue because on Xsplit i can stream at 720p @ 30 fps without noticing any possible lag on the stream while using same settings.

So if anyone knows how to solve or has an idea then please tell me ;)

You might have a faster frame render time if you don't use Monitor capture. Monitor capture is the slowest capture method...Can you use Game Capture instead?

Also, have you tried enabling CFR?

try creating a new scene that has game capture only and switch to that scene when starting your game play.
re enable multithreaded optimizations and put it on "high".

Oh i actually always use Game Capture just sended one Test when i tried to see how Monitor Capture works. However doesnt make a difference for me.

I thought CFR is mostly for Video recording and not really about the streaming.

I'll give it a try tomorrow

I use 2 Scenes already one for Monitor Capture and the other one for Game Capture.

I can try ti enable multithreaded optimizations again and i can put it on "high" but the problem existed there as well i think.

I feel like the problem is about the program somehow not being able to use my Cpu properly, just my guess ;)

Since i know Xsplit uses way more CPU than OBS and even if i have around 80% Cpu usage with Xsplit the stream is running smoother, sadly..

try it, and also make obs's priority on high from task manager.
looking at the log the frame time is fine even on monitor capture. post another log file from your game play. also post a vod so we can check the the actual fps.

So i did what you adviced me and i found the problem.

The first vod i started OBS when i was already in the Loading Screen of League of Legends, means i was already in the game. Then there would be constant FPS.

http://de.twitch.tv/thed5/b/379587611

The second vod i already started capturing my monitor and then switched the Scene to Game CApture as soon as the game started and it lagged. I don't mean really huge lags for Freezes just minor ones who in my opinion get really annyiong as viewer. Also my Ingame wasnt as smooth as when i did the first vod.

http://de.twitch.tv/thed5/b/379588394

Any Ideas how to fix it?

I mean yeah, it's fine but also i bit frustrating because the first vod looks better than the second so i know my system can do these settings without problems but i just cant get this constant :/
