Poor BF3 Performance Help

[Faztastic]

Okay bf3 came out a while ago, i installed played all on ultra it was fine!

Got fed up with the rubbish maps so uninstalled.

Back to Karkand came out i wanted to feel if it has the bf2 nostalgia, reinstalled today.

Installed amd cat 11:12 with latest caps, i go into game try wake island and im getting really bad stutter/lag/pauses when im playing on auto detect graphics setting.

So i think ahh okay maybe VRAM so i turn down the resolution from 1920 too 1680.

Still same problem, then i think what the hell i used to be able to play on this fine.... at settings higher than this.

So then i drop everything down to medium, it is slightly better but im still getting mega freezes now and then especially when flying jet/helicopter... its unplayable.

Try Low and everything works much better. i mean come on has back to karkand really made it that more demanding? my specs are as follows.

i7 2600k @ 4.6ghz
ati 5850 in crossfire
4 gig corsair xms3 ram @ 1600
xfx 750w powersupply
asrock extreme4 z68 motherboard
windows 7 64bit.

Now taskbar only thing running is microsoft security essentials.
lucid virtue which ive disabled
catalyst cc

also this has been installed on a recently reformatted windows.

Any ideas

I think theres a issue regarding performance of the B2K maps. I noticed it strait away, There's a huge difference compared to 64p cq on caspian or any other big map.

Theres quite a few having these issues if you look on the bf3 forums.

Ill check now, i hope it is.

But its really bad this messing about i thought theyd of sorted it all out now. :/

i am still playing on low.

No one seems to be having problems with graphics lag?

Just lower frame rates... i have both.
