Nvidia Optimus- GPU switching problem

Less than "Optimu(m)s"

Hi Guys,

I felt I should register just to post this as I have spent an entire afternoon trying to get and ASUS K53SC i7 to switch to the Nvidia GPU (Geforce GT 520MX) when playing games / Nvidia Demos.

After reading the above posts I decided to remove the Intel drivers (which at this time are the newest available) and let Win 8 just install what ever it wants as the Nvidia drivers (also the most up to date) support Optimus.

Win 8 1st just installed a Microsoft HD3000 driver and then a few seconds later got a new driver, see below:

Intel 9.17.10.2932 with driver date 2012-12-12

Since then Optimus has been switching to the Nvidia GPU as it is supposed to.

I suggest try this and see if does not fix the issue for you.

I tested this by enabling the " Display GPU activity...." setting under "Desktop" in the NVIDIA control panel. This allows you to see how many apps and which apps are using the Nvidia GPU.

I then ran the Nvidia Heaven Benchmark as well as Stone Giant (not full screen so that I can see the taskbar) and the GPU Activity indicator then shows 1 App running.

Best of luck...
