Question / Help Poor game performance when OBS Studio is running

My machine has an i7-5820K (OC'd to 3.9GHz) and a GTX 980. When playing some games while OBS Studio is running, the in-game performance is very choppy with a fluctuating framerate (if it helps, this effect is most noticeable in Minecraft). I tried changing encoders (x264 and NVENC) to no avail. What is causing this issue? It makes competitive play very difficult and puts a strain on my eyes. It's gotten to the point that I'm seriously considering shelling out money to build a separate PC to run OBS.

If you need to know any other of my streaming settings, just let me know!

blod text means obs runs on nvidia card, but what your obs is running on now is a mystery

are you sure you have nvidia drivers working properly? id give DDU a go and reinstall
is your win10 fully updated?

your log is also incomplete. start stream, stop after like 10 min, close obs and post latest log
what i can suggest for now is to use 64bit obs, path is "C:\Program Files (x86)\obs-studio\bin\64bit\obs64.exe"
run it as admin, enable vsync in game, change camera format to MJPEG and make sure you have this isntalled https://www.microsoft.com/en-us/download/confirmation.aspx?id=35
