Obs game capture stuttering

[andybeech]

Hi I'm currently having issues with obs and in fact xsplit they both seem to stutter or lag when capture pc games using the game capture feature. When capturing consoles using my avermedia it's fine but when trying to do pc games it lags. I recently built my new pc i5 7500 gigabyte ga-b250-hd3p 8gb ddr4 corsair vengeance lpx 760 gtx sound blaster z avermedia capture card 120gb ssd 500gb hdd  as I thought it might be my amd fx6100 that I was using so upgraded. Tried reinstalling programs, adjusting some settings. 

Any more suggestions thanks

What frame rate are you capturing at? Try lowing it to 30 FPS, this is common if you are attempting to capture at 60 fps.

First things first OBS settings please ... 

 

Over all ... is OBS very CPU taxing due real time it's encoding (since it's meant to be a broad casting software), don't try to record at high compression rates ergo I recomand to use the "very fast" x264 preset and don't set the bitrate to low but also not rediculously high. This is because if the storage can't catch up at the same time it might cause stutter, too (especially if the storage device is used simultaneously by another software).

 

It is also possible that your game you play is taxing the same threads than OBS does (OBS is more or less using all available threads) you can try to run the game without recording software to watch which threads the workload get spread and after that you can set priority/affinity for OBS on the unused threads (I think OBS has a setting or option for this now but you can use the taskmanager for this, too)

 

 

But for further information please give us some more info on OBS settings.

 

PS: do you want to make high footage for youtube for example? For the best quality you record with a more or less highest bitrate possible (at a level your storage can handle it and maybe is taxed 70%) and than upload it as uncompressed as possible, too. it will take -especially with a slow upload rate (RIP my own abysmal 1,2Mbit at this point)- forever but the YT compression itself will be faster and the resulted YT compressed video will have better quality.

If you want just some OK to good quality footage for yourself you can use a lower bitrate, this can also be uploaded with OK quality to youtube but the bigggest advantage for sure is that the video file size is only very huge and not GB chewing huge.

yea im streaming at 720p 30fps did try 25fps when I had my AMD cpu as that was quite a week chip.

Thanks for the very detailed reply with the recording side of things I tend to forget about what bitrate im using its just set to 5mbs mp4 its mainly the streaming side for Twitch and youtube im looking at currently as thats the main issue im having. I have been streaming at 720p 25fps or 30fps currently at 3mbs bitrate as got 21mb upload and 222mb download with 9ms ping.

Tried both the x264 and nvenc encoder cant use avermedia while capture with it, mainly that applies for console but console only seems to work well.

Also noticed get some heavy cpu usage with the i5 7500 too and some crazy bitrate and frame drops in xsplit.
