Now to my problem, i have returned after a year break and wanted to stream again, the new Path of Exile season. The problem is when i have the Streamlabs OBS application open (and while streaming) my game gets choppy, i get consistent 80-100fps but every 2 sec it drops to like below 20 for 0.2-0.5sec. this makes it very unconfortable to play. My GPU is rarely over 90% usage, and cpu rarely over 40%
CPU: I7 6700k
GPU: gtx 970

If you are getting lagged frames, then this would be an indication of an overloaded GPU where you can then try to reduce the in-game quality, limit in-game FPS (perhaps with v-sync), reduce render resolution if available and also disable Windows 10 Game Bar if enabled.
Skipped frames would indicate an overloaded CPU usually in combination with x264 encoding, consider using NVENC, AMD, or QSV if available instead.
Dropped frames would indicate a network issue, try restarting both your modem and router and manually select the closest or second closest server to stream to in Streamlabs OBS Settings > Stream.
