Problem Details:
In the cutting edge build, ticking the "full screen" option doesn't appear to work as intended, I think. It feels more like borderless window - alt-tabbing from the game is incredibly quick, my FPS is the same as if I was using borderless window and I still experience the infamous lag of Windows 8.1. I'm not sure if this is an intentional change or something solely to do with my system but on stable, Fullscreen works as intended (no lag and it takes a few seconds to alt-tab out of the game).
