I've just installed the latest drivers from Microsoft website. That didn't seem to much. I'm downloading build 10130 hoping to god that most of these issues would be fixed 

You are probably running with the basic "microsoft basic display adapter" drivers, look for updates, restart it and check device manager.

I can't really say I recommend windows 10 on a surface pro 3 now, but it's definitely not as bad as you are experiencing.

Hello, I foolishly installed windows 10 preview build thinking that it would work better than windows 10.. Boy was I wrong. Everything is extremely choppy (we're talking like 10fps).. Does anyone know of a fix or how go back to windows 8.1?

(This is build 10074)

Windows 10 on Surfacr pro 3 i3 lag?
