Battlefield low FPS

BF3 will seriously tax GPU's. Have you tried bringing the settings down a bit and turning off AA? I found that reducing the settings on BF3 didn't really make it look that much worse but it helped the performance.

Make sure you're Nvidia driver is a recent one too. BF3 was not good on the Dell version of the Nvidia driver when I started playing it. Make sure you get it straight from Nvidia.
 
I find that i can keep the settings on high if i reduce the resolution.
Dropping it a couple of bars down should put a little less strain on the GPU.

Other than that, I found the latest version of Nvidia drivers not the greatest. I rolled back one version and all was ok.
 
It's not that your laptop doesn't "support" the game, AA (anti aliasing) since it's inception has been the killer of performance. Even high-end machines will drop in frame rate if to many settings have been turned off. A good way to prevent performance lowering settings is to know which settings affect games more the others. From my 15 years of experience of gaming and being in the computer performance world I have found the following settings are almost always responsible for low frame rates.

Lower Frame Rates
1. Anti Aliasing
2. Post processing effects (HDR rendering, bloom (not so much anymore), per vertex lighting)
3. High quality shadows (can makes certain games unplayable if set to high)
4. Vertical Sync (throws away partially rendered frames to eliminate page tearing, only good if you computer can render a consistent 60+ fps which is the RR of most monitors)
5. View distance (especially if you have AA, post processing or HQ shadows turned on)



Things you can crank and will have little to no effect on performance
1. Texture quality
2. Anisotropic filtering
3. Decal quality and quantity (provided you have a GPU with a good amount of memory)
4. Radial Blur or Depth of Field.

I hope this helps. When I play a new game such as Batman: Arkham City I begin by setting texture settings high and resolution to my native 1080P then play. If the frame rate is good I slowly start changing settings such as AA and light/shadow settings up until the frame rate begins to drop then I stop. That way that game looks as good as it can without having to sacrifice frame rate (playability).

Hope this helps.

On my experience with BF3 on my M14X, I can play on High settings on most maps, but on more 'graphical' maps with dust in the air and such (I can never remember map names) I have to turn down to Medium settings. The reason the performance is lacking with the machine is because of the GPU's capability, specifically the core clock speed. Grouchomarxx summed it up pretty well. With having too many settings up and then playing at high resolutions, the GPU will reach it's max potential and not be able to handle the settings at playable frame rates. That's the sad limitations of laptops. But hey, we look awesome while playing on them while we're on the go, eh? :]
