Switching between a GeForce 635M and Intel HD4000

[OinkBoink]

Okay, so I have a laptop which has both these GPUs. Games seem to detect only the Intel GPU. I've installed the latest nVidia drivers. I thought I'd disable Intel HD 4000 in the Device Manager, but doing this turned my monitor off. I restarted the system (the font size became really big on doing this) and now when I try to open nVidia's control panel, it tells me that I don't have an nVidia card attached to my display.

How do I run my laptop on the GeForce?

GPU-Z shows my core and memory clocks at 0 & 0 MHz respectively for the GeForce. Why is this so?

AnandTech did a right up about it here on Nvidia Optimus (what you have on your laptop):

PC Mag also explains it here:

I think it does it is automatic and there is "no manual way to do it" correct me if I am wrong... if you have a descrete Nvidia GPU you have Optimus - the software side decides if it is better to route the graphics rendering GPU in application intensive jobs (like gaming) to the Nvidia GPU and if it is not intensive it routes it to the HD 4000.

How do I know which GPU a game/application is using when it's running? Some games just detect the IGP (HD4000) and not the dGPU (GeForce).

Also, again, why are my GeForce core and memory clocks showing up as having zilch values on GPU-Z? The HD4000's clock speeds show up just fine.

Okay, enabling the HD4000 graphics ended up showing my GeForce core and memory clocks. But I still want to know how I can know if a game/application is using the IGP or dGPU and what I can do if the dGPU is not detected.

Please help me out here guys. This nVidia Optimus thing is a pain and many people are experiencing issues with it. Please try and address what I've asked.

Re activate the hd 4000 (try to set your notebook as it was before you started fiddling around with it).

Try opening nvidia control panel. If it opens then set it to use the "high performance nvidia processor".

Power options should be on high performance/balanced.
