Yea the new version is pretty terrible, have you disabled game mode in windows settings and nvidia shawdowplay in Geforce Experience?
If yes and still lagging, try going back to an older version, that seems to solve the problem for now.

@DannyZ is all over it. Game Bar and Game DVR are interfering little things. You want to make sure that OBS is the only program that's trying to tap into your game, if there's more than one, they fight over it.

Also, if your game is maxing out your GPU, that causes problems too. It's strangely common. Lower your graphics and cap your FPS in game to make sure that the graphics card isn't 100% in use, you want it 90% or lower in the most complicated fight scenes. Once you've secured this, give OBS another whirl.

i made sure that shadow play and the windows thing are turned off and i did notice a lot better performance, however there was still a little, but it seemed to happen after a little bit of gameplay, i always run my games and the lowest possible setting because i play a lot of competitive so i wanna get the best fps i can, i will check the usage next time i am in. Danny also said about change back to an older version of obs because it is more stable. how would one go about doing that???and which version should i go back to to get the best performance?

P.s i am assuming i should cap my fps to my monitor hrtz?

You just need to cap your game fps to a rate that is a little lower than what it can achieve. For example, Overwatch has a hard cap of 300, but my monitor is 144. If my game will run uncapped at 180, then the 144 mark seems like a great solution. But if my monitor only gets to 150, and sometimes drops to 140 mid-teamfight.... Then there's a new problem. It means if I cap it to 144, during a team-fight I will get lag on the stream. So I'd cap it to 120 and take the performance hit to my gameplay, for the sake of the stream.

I do agree that v22 of OBS seemed to compete for GPU resources during the render phase a little better than v23 does. But I'm not 100% sure it isn't just because so many people are using the CUDA presets without realising what they're doing. So I don't know for sure. It's worth a shot, I don't know where to find it though. I have a copy of the installation still on my disk but I'm terrified of copyright laws.... :(

I can run Overwatch at 300fps not recording. My monitor is 165 hrtz. Should i just cap the fps to 200? or go the the hrtz of my my monitor, so 165?

i just had a look at it and tried to cap my fps.. i noticed that it keeps dropping below 100 to like 80....... but the it goes straight back to 300....... wtf

If you're hitting 300 I would normally think that 200 is more than enough of a cut. The reason for your sudden drops could be anything.... If your graphics quality in-game isn't set to the lowest, try lower it and see if you get the same fluctuation. I have an RTX 2070 and my monitor is 144Hz, but when I play without streaming, I leave it uncapped and it smashes 200, and sometimes drops down to around 160 or so that I notice. When I'm streaming, I cap it to 120 and it doesn't skip a beat.

Your mileage may vary.

Whatever is causing you to drop to 80 while OBS is not open, that is the thing you need to find. It could be the game itself, it could be something else running in Windows that is interfering.
