Question / Help Low CPU load, but low FPS.

Hello,

am trying for a while now, but still cant figure it.

My problem is my low FPS in CSGO - without OBS i have 180+ FPS. together with 144Hz monitor. With only CS, my CPU is sitting on <30%.
With OBS, regardless of setting i have under 80%(even with medium preset), but my fps starts to dip under 144fps, which causes problem with screen-tearing and unpleasant feel in competitive game like CSGO.
Is there any hint or way to know, what is bottlenecking my FPS in-game?

Examples of CSGO+OBS with CPU load in left top corner. If you find any extreme dips in fps, thats when i connected to PC via teamviewer - i was doing these tests from work remotely.

CSGO with "veryfast" "high" "film" "vbr" "CRF 20" "bitrate 2700" "720p downscaled from 1080p"

CSGO with "medium" "high" "film" "vbr" "CRF 20" "bitrate 2700" "720p downscaled from 1080p"

Log from "veryfast" attached

EDIT: Forgot to mention, my CPU is OC´d to 4,3GHZ(which is not showing in log. GK is GTX 1070 and is NOT bottleneck, as with CSGO 40% load is rare.
