Question / Help Having some problems with stream...

Hi guys!

I am having some weird stuff going on at my stream.

First, I was streaming 3500 bitrate 720p and 48FPS. Stream was running good! Then I decided to lower my bitrate that more viewers could enjoy my stream. I decided to go with 540p 48FPS and 2000 bitrate. That didn't quite work out, since i was having some weird FPS drops on my stream. I tried 2500kbps and I still get those FPS drops. Weird?

Can someone help me out, what I am missing here?

Custom crf values are ignored when the rate control method is set to CBR so that wouldn't really cause a problem.

Please be more detailed about what you mean by "weird FPS drops". You mean ingame performance? Or the stream's video on Twitch? Does a local recording exhibit the same problem?

I am not sure about the local recording, but definetly the stream has some mild fps drops.

The drops are really visible when "surfing" in CSGO (Don't know if you know surfing :D). The stream looks really smooth, and for couple seconds the FPS goes to somewhere around 10-15.
 
So the FPS ingame is what drops. Are you using either vsync or fps_max to limit your ingame frame rate? If not please try it and see if it helps. You can also run CS:GO with the -high param to give it higher process priority.

Oh sorry I think I wasn't quite clear enough!

The ingame FPS is awesome, mostly hitting +200FPS. It's the stream that is having some problems :/

Also, I have 144Hz monitor, is that a problem?
 
Letting the ingame FPS run uncapped means it eats up a ton of extra CPU and GPU resources, possibly not leaving enough left for OBS to run the way you want.

Is this a bitrate issue? Could I go with 2000 kbps and these settings in your opinion?

BTW thanks a ton for your help (and others help) so far! This response has been amazing!
 
No, unlikely to be a bitrate issue unless the problem is visible only while watching the stream.

Edit: For a 144 Hz monitor, if you don't want to enable vsync, try adding +fps_max 144 (or 150 or something in there) so you aren't rendering a bunch of extra frames your monitor can't display anyway.

Ok so it seems it's not that bad (I didn't notice any fps drops) in local recordings. Going up in bitrates seems to ease the problem a little (Tried 540p 48FPS and 3500 kbps). Do I really require that big bitrate?
