Question / Help OBS Stutter/Freezes even in Preview mode

[gamingoodz]

I am having an issue with trying to stream using OBS.. I have put a lot of work into my channel and getting things set up to start streaming but one thing is holding me back from actually streaming..

While streaming or even previewing the stream the video will stutter or freeze off and on for maybe 1-4 seconds every once in a while.. It happens often enough that Its keeping me from streaming.

It seems to happen randomly or it might be when there is motion on the screen I can't really tell so I checked my CPU usage and its not capping out.. I also checked my Upload speeds Before I realized it was also doing it even in the stream preview and my upload is 10,000kbps or 10mbps..

I've tried lowering the Bitrate down to 2k with no success.. I've also tried changing the cpu preset to superfast instead of veryfast with no effect.

I've tried 32bit and 64bit OBS ( Im using 64 windows ) and both have the same issue.

I'm really stumped here and I'm not sure what to do to fix this..

Here is a Highlight from a test stream I did that shows the issue very well:

Here is my Log file from my last preview test: ( Using 32 bit OBS ) ( I'm on 64 bit windows but the issue happens in both version of OBS)

I would appreciate any help regarding this issue as it is the last thing keeping me from starting my streaming hobby :)

Thanks

It seems like you're using window capture, there's not two of them are there? That would be bad.

If not, then first could you try with game capture instead? I just want to verify that it's not window capture causing this (though it really shouldn't be). Very weird, haven't seen anything like this before from other users.

beside your capture methods ... for some odd reason 1st gen i7's have problem with 1080p@30 they tend to perform kinda bad.

720@30 shouldnt be a problem after you set some proper scenes

Im only using Game capture not window capture.

I really hope this is not true I have no interest in streaming then If I can't stream at 1080p that would be so sad :( .... I've looked at my cpu load while it was skipping and it was not maxed out.. It was high across all cores but not mzed , probably about %80 at the most

Also I tried turning the cpu preset on superfast instead of very fast and it didn't seem to help at all..

 

[gamingoodz]

Ok I just tried to downscale to 720p and even in the preview mode it was still stuttering / freezing just as bad as at 1080p.... I'm stumped... I might have to download the xsplit trial and see if its something on my end or on OBS's..

 

[alpinlol]

its a weird idea ... since you set everything correctly but give aero disabled a try and delete all scenes and try only a monitor capture scene (just as a test) and then get another scene with game capture and see if this helps in anyway it doesnt really makes sense but its worth a try



i hope you get 80% cpu usage while playing + 1080p streaming. its still quite high since games can spike quite a bit from time to time

also with your cpu you shouldnt really go with a faster preset it should be able to handle stuff with veryfast since the quality loss with super or ultra would be way too high if you are planning on 1080p

Weird I left all of my settings and scenes the same ( game capture ) but disabled Aero and in the stream preview it doesn't seem to be stuttering or freezing anymore....

That doesn't make any sense to me tho because the scene is in Game capture not desktop capture..Aero shouldn't effect it..

I still need to test it actually streaming tho , I don't want to get my hopes up just yet.. I'll try to stream really quick and see if it is still happening during streaming.

 

[gamingoodz]

Looks like somehow I switched it to "window" capture instead of game capture at some point.. Which probably explains why disabling aero fixed the stuttering lol.. Still trying to stream really quick and see if its fixed or not..

I didn't realize until I just started to stream to test it and opened raidcall and seen it pop up on my stream... I was like oooo ...

SO switching it to game and seeing if its fixed.

 

[alpinlol]

makes sure to use different scenes for game capture ... game capture as far as i have tested it performs the same with aero disabled or enabled actually the game itselfs gets like 5 fps more with aero disabled for kinda obvious reasons your gpu doesnt have to work on.

but yeah just make sure that game capture always runs in its own scene you can use obs scene switcher ... its somewhere in the forum its a plugin which will switch scenes if you switch into games

but make sure if you want to use window capture you have to turn on aero if you want to use monitor capture disable aero game capture works with both settings
