Extremely choppy game play in windowed mode + FPS decrease

[Gabriel Goldberg]

Hi, my name is Gabriel.

I'm a frequent gamer, and I have a pretty big problem. Whenever I play any games in windowed mode (not f11), my gameplay is super choppy! My monitor is 1920x1080 60Hz, but I use 1280x720 60Hz. In windowed it also looks a lot less smoother. Almost as if it's a 45Hz monitor! I play my games in 720p, (More fps) and in fullscreen f11 it's fine, but in windowed mode the FPS drops from about 200 (in minecraft) to about 120 which somehow looks less smooth. My drivers are all updated, I don't know what is causing this. Here are my specs:

Windowed mode gives the application/game a lower priority so can introduce input lag and/or stuttering, you should always play games in fullscreen when possible.
