Losing fps in minecraft when obs open

[MrRandomPVP]

I usually get 100-150 fps in minecraft but when i open obs it drops to 70-60 and when i record it drops to 30-40 which is kinda unplayable for me.
I have a low end pc and record in 60 fps
specs:
13-3rd gen
4gb ram
and idk

Try disabling the preview while you're encoding so your PC isn't wasting resources to display the preview in the OBS window. Otherwise you will have to tweak minecraft settings and encoder settings.
