Hi, I thought this might be informative for those still tweaking their graphics performance or for those who is planing on upgrading their system.
REAL WORLD APPLICATION ONLY! no graph nor statistical bs.
feel free to also post resources here to improve performance.

TIPS: in the game, press ` (next to numeric 1) to activate console. Use the command Render.DrawFps 1 to show current frames per sec)

Average FPS on 64 player servers: 33-35 FPS, dips lowest at about +-29FPS on heavy scenes. Stable & smooth enough for me.

This is not autodetect settings, I pushed it higher until it gets noticeably laggy then I dropped it back down to somewhere comfortably smooth.

Going to autodetect settings at some high some medium gave me 45 FPS.

So yes, you don't need to spend so much to get a good enough rig. RM 440 for this performance at only 31% of the cost of a dual SLI Rig for 6870 or only 18% of the cost of a high end 6990.

All medium @ 1600x900 average 35 fps during multiplayer.

Single player is smoother, average 45 fps.

how do you think if i ran this game on the same spec except the proc is i5-2410m 2.3ghz and I lower the resolution to 1024??
can still get over 30 fps?

Intel Core i5 760 2.8Ghz

The graphic in Battlefield 3 is seriously imbalance, the FPS can sometime go up and go down very quickly.

if lower to 1024, can get more than 40fps

Specs as in sig

Resolution: 1680 x 1050
Texture: ULTRA
Shadow: ULTRA
Effects: ULTRA
Mesh: ULTRA
Terrain: ULTRA
Terrain Decor: ULTRA
Antialiasing Deffered: OFF
Antialiasing Post: OFF
Motion Blur: 70
Anisotropic: 1x
Ambient Occlusion: OFF

Average: 75fps - 200fps depending on scenery

Looks like my dual GTX 580 under perform compare to your dual GTX 570?

Lower resolution and I turned off MSAA which is an FPS killer in this game. So in a way it balances out. Also this game uses quite a lot of memory, so you might see an improvement with another 4GB in your rig

But now I am very satisfied with my current setting, having average 100fps in 120Hz monitor, very smooth gameplay.

If I set the resolution that is lower than 1920 x 1080, then I will lose the Full HD.

Yeah. I mean i am running on a lower reso since that is my native reso so my vram usage is lower

AMD Opteron 180
3GB RAM
Vista 32 bit
ATI HD4870

All low, FPS 15 to 20.

Windows 7 64 bit SP1
Intel i7 2600K @ 3.40GHz
8GB RAM
Samsung Spinpoint F3 1TB HDD
GeForce GTX 580 1.5GB SLi
Driver version 285.62

Average FPS on 64 player servers: 85fps - 150 fps @ 1920 x 1080
Settings : Ultra

Looks like both of us have the same specification in our rig.
