How can I fix obs lagg

[FireBuster12]

Hello Tomshardware,

I play every day minecraft with 200fps ingame, but I want to record it.
I have looked for a good recording program, and I found: "OBS"

If I go to the window obs then I have 30 fps in obs and in minecraft 120fps (I can see that by a preview window). When I go to minecraft and want to record then i have 1fps in obs and 120 fps in minecraft

How can I fix this? When I go to minecraft that obs have 30fps and in minecraft i have 120 fps?

Specs:
CPU: AMD a10-7870k temp: 68C
graphics Card: AMD Radeon r7 graphics (Integraded cpu graphics card) Temp: 19
Ram: 8gb

While recording!Go to task manager find "Open Broadcaster Software" right click on it and select go to details right click on it again(now it's obs.exe) and select priority and put it to real time.
That will insure that obs always uses as much cpu as it needs to get the recording you set up no matter how much it has to slow down the game.
