Hello, i have a problem with my laptop not switching to my graphics card when I play games. My specs are...

8 gigs of ram
GT 640m
i7-3632QM 3.0 GHz

The things i have tried are going into my Nvidia control panel and setting my default PhysX processor to my 640m. I also manually made sure that each program and game I used was set to "High-Performace Nvidia processor". Also before i launch the game i right click it and run it with the right GPU. Yet the games still run on the on-board. I heard that this might have something to do with Nvidias Optimus?

Here are some examples...

Baldurs Gate II: EE (Even though the game ran fine, it's just an example)

Any suggestions would be great!

Hate to state the obvious, but have you installed all the latest drivers for your hardware (both graphics, chipset, etc...) ? It's possible that simple driver updates might fix the issue

 

From Invidia's website:

Using NVIDIA's Optimus technology, when the discrete GPU is handling all the rendering duties, the final image output to the display is still handled by the Intel integrated graphics processor (IGP). In effect, the IGP is only being used as a simple display controller, resulting in a seamless, flicker-free experience with no need to reboot.

 

Is it possible that the 640M is actually being used, but only appears that the IGP is doing the work?

 

I've never used that hardware and Optimus before so I'm not sure how it's status is reported to the user. Maybe someone who has this setup will chime in with a more accurate explanation.


After the game, the King and the Pawn go into the same box...
