noOptimusFix
games on laptop internal screen while using external graphics adapter
Small utility to play games on laptop's screen when using external gpu device (like EXP GDC) and not having Optimus (gpu switching) technology support. Works only for games that can be started in windowed mode, like Crysis, and that choose gpu based on main display screen (most games).
Note: this is currently pre-alpha release and meant only for people who are familiar with c# programming as will generally require source code level adjustment to make it work on your particular game/system.
