Question / Help OBS running in general causing FPS drop?

[kyle17of09]

Currently when I play CS:GO I obtain over 300+ FPS with no problem at all. With that being said I could be just playing CS and if i open OBS i notice my FPS will just instantly drop to under 100 and skip between 100ish to around 40's which is totally bizarre and annoying. So the problem isn't with encoding or anything because I'm not even streaming or recording!

My Specs

• GTX 1080 8GB
• I7-4790k 4.0 Ghz
• Ripjaws 16gb ram
• 2x Asus 144 HZ monitors

OBS running in general causing FPS drop?

In short yes, you can turn off preview and maybe reduce the effect a littlebit, but getting rid of it is impossible on a single pc setup.

Yes, the GPU will render the OBS scene, even if you are not recording.
Btw: Why using over 300fps when only 144Hz are visible to you?
Keep in mind, that you stream will stutter, when you do not cap your fps.

More FPS reduce input lag in a certain way which is obviously the most limiting factor in an FPS

Ah okay, I thought the human player is the limiting factor, when he tries to react to the <8ms delayed picture, he sees. ;-)
Maybe <8ms is still way too much...I'm just a casual player that wants smooth gameplay+video.
Nevertheless, the video/stream will stutter without a fps cap.

Well im not counting the human player into the calculation here :P

I do cap my frames at 300, which is never a problem and I always hit the max. Even if i was to cap it at 144fps when having OBS open it'd still stutter and constantly go from 30-100 frames constantly.

Ok, then we have to wait for the log.

Idk if i can close this forum or not, but I've resolved the issue. Whenever i run OBS with a game Full screen windowed it causes extreme lag and fps drops. I simply just activated full screen mode and my frame run at a constant 200+. I apologize for the stress. It really was quite simple. If anyone has this problem again I guess we will know for future reference running a game at full screen windowed causes fps drops.... Sorry!

Hey guys I have the same problem but with warzone. I play 144 no problem. But as soon as I turn obs goes down to 60-70. If I disable preview goes up to 80-90 but I can't get 144 and also sometimes makes my game skip but my stream would be fine.

I run a single pc
2700x cpu
2080gpu
16gb ram
144azus monitor.
Can anyone help me out please . I would not mind the frame drops to 100 but it sometimes drops in a way that I can't play the game like feel so choppy to play thank you in advance

I always just set my common FPS value to what my source is and OBS just works. If I want "30" FPS then I set my source to 29.97 NTSC and common FPS value to 29.97. If I want "60" FPS then I set my source to 59.94 and common FPS value to 59.94
