Hi,
I've noticed big improvement post-patch, getting avg 30fps over London and 50 over water with custom settings (1680x1050 mostly medium, buildings low, trees off, shadows off, grass on, roads on), game still looks awesome quite smooth gameplay stuttering completely disappeared when I disabled Aero desktop in Windows 7 (!!) but there are micro freezes little bit which I assume is my GFX bottleneck however the game is playable for me
Anyone noticed the MP server browser is now working?
Btw. I think this game needs latest GFX like GTX580 or eq ATI singlecore (until they figure out SLI / Crossfire support ) with lots of mem so not sure why people complain about performance. It was playable for me before beta patch and my rig is 2 years old (already?

)...so an upgrade is worth to do - will need it for BF3 anyway
A friend has similar results with his intel quadcore @ 2,5GHz (not sure about the type) and ASUS MB with same GFX like me, W7 64bit
the rig:
Win 7 64-bit
Q9650 @ 3,6GHz
4GB DDR3 @ 1066
ASUS Striker II Extreme
GTX280 OC 1GB x2 (no SLI for CoD

)
OS and CoD on 60GB SSD
Thanks and keep up the great work
