Have an NVIDIA GPU + Integrated Card? Read this.

But other people don't.

Mine was on "Auto" for months, most decent games are fine and I never noticed.

Then I noticed some games which really shouldn't have had issues were just not performing very well - found out they we're just ignoring my GPU.

Good times :)

Why would you be nice to someone who helps the community? .____.

I heard that sometimes this just makes the performance worse because the main GPU downclocks/wait for the PhysX processor to send data

Haha, I have no idea :P I've never ran more than 1 GPU at a time!

A 9800gt paired with a 560 should be fine. If you had like a 670/680, then I wouldn't recommend having a 9800gt as PhysX. The more powerful your main GPU is, the more you have to worry about your PPU bottlenecking it. But with a 560, the 9800gt should be a nice pair. You can see here, when having a PPU that is too weak it'll drag down performance. But then there's a point where your performance increase somewhat tops out. Your PPU doesn't have to be THAT strong. I see people with dual 680s and a 560ti as a PPU, which is useless as the 680s are more than capable of handling that on their own.

name your CPU and I will tell you...

Device Manager -> click the dropdown triangle for 'Display Adapters'

Do you you have one item or two listed?

I suppose you could, but laptop users do have to consider battery. No use of running a GPU for everything when the integrated card can run non-3D tasks such as browsing.

This method is also much easier for most and can be done on-the-fly if need be.

I'm not sure if there is a Global Setting (there likely is but I'm not familiar with the panel).

You can try right clicking the .exe of the program you want to run and look for "Run with Graphics Processor", it may allow you to select your Radeon.

Hopefully someone else has more info for you :)

Not really, keep in mind this is ONLY for the 3D Settings (Hence the option being "Manage 3D Settings").

If you change the Global Setting to "High Performance NVIDIA" and apply it, then go back to the Program Settings tab, you will see non-3D applications (like your browser or iTunes) will still say Integrated Graphics.

This fix will not run your GPU at all times for all applications.

True, but then you would be using the GPU for everything rather than just 3D/gaming tasks. Either way works though.

Read my reply mtkyebra above, this will only kick in for 3D enabled games, not all apps :)

Unless you mean gaming while on battery, then yes it will kill the battery faster.

I don't have Optimus, yet I still had this problem :P
But yeah, only for laptops.

i know,when i tried playing it on a integrated chip(nvidia)it had a black screen but even with a dedicated nvidia gpu it still has the black screen.
