Question / Help Game capture running lower FPS than window capture

Not sure what my issue is and i wish i could get this to go away

When I stream CS:GO in game I have roughly 250 FPS, doesn't really ever drop below 200. All my encoding settings /etc are fine and I know to be good and working, but when I stream using game capture my stream looks like its about 15 FPS and its very choppy. If I change to using monitor capture (which I would prefer not to do), the streams FPS looks like its 45, where I have it configured and the chopy-ness seems to goes away. I notice no change in FPS in game between monitor capture and game capture but the stream FPS is higher and better looking when using monitor capture.

System:

Windows 10
i7-4790k
GTX 970 SC (2x sli)
z97 chipset
16 gb ram

Network isn't an issue, but heres the specs anyways:

100 MbPS down
75 MbPS up

All drivers are up to date on my system:

OBS settings:

bitrate: 3000
CBR padding enabled
no CBS
1920x1080 native
downscale 1.5
lanczos filter
multithreaded optimizations enabled
scene buffer time: 400 MS
x264: veryfast
keyframe interval: 2
use CFR enabled

^ pretty sure those are all the settings you could want to see

Log is attached. Please help, my stream is at a standstill without game capture working properly.

NB: If anyone has any other recommendations to improve the quality of my stream's video - I think I have some headroom on hardware so all ideas are welcome and I will try anything!

thanks.

I've just thought of something that might have an impact and might be of help to you guys:

My CSGO launch options configure the game to run on 8 threads and have a high process priority.

could x264 be having an issue using one of the cores of my CPU if CSGO is actually running on all 8?

csgo is very known to park / unpark cores and that event causes incredible frame studdering. Thats why i run those two launch options.
 
should i disable SLi and try to stream that way? why would this cause an issue - i dont understand the routing of game capture.

never the less - will disable SLi and try game capture again.;
 
looks like this fixed it... but now my game performs far worse than it ever did when streaming.

any ideas?
