Windows 7: GTX 460 stagering in BF3! help/advice!

Im not even sure this the right section for this,kinda new here (1 post ) but here goes.
My BF3 staggers a LOT,whenever i do something new and mostly just randomly,i cant even freaking walk in a straight line without the frames droping to less then 15fps.The problem is very severe and its ONLY happening in Battlefield 3. No matter online MP or offline SP its there. The frames drop to 1-2fps even. I have the latest drivers.
I have tried it on all resolutions my moniter can support which isnt many since the max is 1280x1024. Also tried all settings,medium,high,ultra,custom with no AA whatsoever.
Any and all help will be appreciated and again,ive played more then 5 games like Darksiders 2,sleeping dogs with good FPS and no problems at all. Only in BF3.

You might consider increasing the amount of RAM for your system.
2GB is the bare minimum for a 64 bit Windows 7.

what is your fps for sleeping dogs and in what options?

Try updating to the latest video drivers and also adding more ram memory like make it 4gbs would give the game and windows a boost.Also make sure the game is updated to the latest patch if it has any.
EDIT:Another idea I would like to add is check your nvdia panel settings try setting those settings to performance.

I agree with the guys above 2gb may be the real issue.. You should consider upgrading to 4gb at least.

Recommended system requirements for Battlefield 3

• OS: Windows 7 64-bit
• Processor: Quad-core Intel or AMD CPU
• RAM: 4GB
• Graphics card: DirectX 11 Nvidia or AMD ATI card, Nvidia GeForce GTX 560 or ATI Radeon 6950.
• Graphics card memory: 1 GB
• Sound card: DirectX compatibl sound card
• Hard drive: 15 GB for disc version or 10 GB for digital version

i get 40-50fps average at full settings (everything) except AA.

the game is ALWAYS updated otherwise i cant play it,and in the nvidea panel i have it in the middle (b/w performance and quality,i will try it again on performance.
And as for everyone else,i know i know abt the ram,every person i know tells me to upgrade but its running perfectly fine all other games and i simply dont think this the problem. Plus i have soo many other things id rather upgrade like a good casing and half a dozen LED fans

I notice no fps increase when switching from Ultra to High. Biggest fps difference is when I turn off AA.

ummmm yea sure..ok.....i didnt say there was big FPS difference when switching from high to ultra,i just told him what FPS i got.
