Battlefield 3 and a GTX260M need help with settings

I've been playing the BF3 beta a lot lately and i'm constantly switching my video card settings up as i'm having issues getting a decent frame rate. Now I've tried to customise the settings as i want to get the best play out of this with out using pre set.

I have an Alienware M15X that uses the GTX260M and has a i7 intel quad core.

If anyone is able to help me with the issue please do!

I'd set the following settings up as an aid:
- Performance manage mode: Prefer maximum performance

- Texture filtering - Negative LOD bias: Allow

- Texture filtering - Trilinear optimization: On

- Threaded optimization: On

But unfortunately with any mobile-grade GPU you shouldn't be expecting very good performance in a game like Battlefield 3.

Where do i edit these settings?

In the NVIDIA Control Panel's "Manage 3D Settings"

battlefield 3 runs fine on my "mobile grade gpu"

Different definitions of "fine", I suppose.
