Bug Report FPS issues when game is in focus, but when the game is clicked away OBS runs fine

[OG See OH Zee]

I have discovered this problem which is only present in Windows 10 (since I upgraded last Summer) but the problem isn't in Windows 8.1 that OBS has been causing framerate issues when focusing on a game with GPU usage at max, but when I click away from the game window such as the video being posted, OBS doesn't have the framerate issue, even if the game is using all GPU.

Video showing evidence with an FPS overlay on OBS Studio: https://www.youtube.com/watch?v=_NWXqNZpUJU

EDIT: Turns out the GPU usage is only 95% when OBS Classic/Studio shows the framerate issues when I ran the game Depth while it's in focus. Depth alone used all 98-99% on my setup. VRAM isn't an issue because it showed that I only used 900MB out of 2GB

The 'game' is ran in Windowed mode. Set the game to Full Screen and this should fix the issue. With a game being fullscreen-windowed or windowed, I don't know of a way to set the gpu to focus on active window.
