Question / Help massive frame drops with game capture, none with display capture?

When I run a game in fullscreen windowed and use display capture I get 0 dropped frames even when upping the quality heaps, but when I use game capture and run the game in fullscreen I get hundreds of dropped frames instantly even with much much lower settings, my cpu and gpu usage are both under 25% usage with either, is there some setting I am missing when setting up game capture?
 
I dropped like 500 frames in the first 30 seconds of the game capture stream, I was watchin on my laptop and it was visibly jittery whereas the other was nice and smooth
