Video Games Running Really Slow On New Windows 8.1 Laptop! Help?

[Sicarisan]

First off, thanks for reading.
I just purchased a Dell Inspiron, and I decided to play some games to kill time.
I thought for the price I paid, and the general specs of it, I could some of the latest games on it.
I tried Far Cry 4, but it was seriously choppy. Even games as old as Battlefield 3 don't run smoothly unless on the lowest settings.
My guess is that software is using the integrated Intel GPU instead of the dedicated Radeon one.
I know that my Radeon GPU has about 4 gigs of RAM, which should be enough for Battlefield 3.

But often, when I open up software such as Photoshop or even GPU-Z, I get a notification bubble saying the Intel drivers have crashed (and recovered), the reason for which is still beyond me.

Here are the specs from CPU-Z and some of the graphics card using GPU-Z.

This might help too.

And my GPU, which says it has 0 MB of memory, but as far as I know this is an error in GPU-Z.

Basic properties, just for good measure...

I tried updating drivers, but then I completely lost the option for switchable graphics, so I had to rollback.
I've had this problem on my previous HP Pavilion laptop as well. It seems like Radeon hates me for some reason. Do you suggest I take it back to the store?
Any solutions are greatly appreciated...

The R7 should be able to play those games which means it is not switching to it. Try changing it in the catalyst control panel.

Check if you are on power saving mode. When you are on power saving mode they normally switch to integrated graphics (intel Hd graphics). Switch to High performance mode.

To get there, Goto The battery icon in task bar and click on the icon. Then a little tab thing will pop up from task bar and you select more power options. Then a window tan will open and you check High performance.
