OBS Making The Whole PC and Game Lag


New Member
Hello, I couldn't find a thread so I created one.

I'm not a computer expert, but I know a lot about them, same goes with the software. My PC Is a beast, and when I want to stream a game or record it, I always get
Stutters or lag spikes. Example: GTA runs in 180 FPS, when I fire up OBS, it goes down to 40. Fortnite runs in 500 FPS, with OBS open, it goes to 60 or less.
If I need a log to attach, I'll need further help with that since I don't know how.

I really need help because I'm a youtuber and a streamer so I need to fix this. Here are my PC specs:

Ryzen 9 3900X w / Stock Cooler
RTX 2070 Super Gaming OC
Asus TUF X570 Plus
16GB HyperX 3600MHZ w / DOCP
1tb Kingston 2200 NVME
4tb Toshiba X300 Performance
Corsair TX850M PSU

DISCLAIMER: I assembled the PC myself 2 months ago and It had no problems until now.
