Maybe when AMD/ATI will release new driver (Catalyst 11.10) something will change, but for now the date of final realease is unknown. The most recent version is "Preview 3" and you can find it at http://support.amd.com/us/kbarticles/Pages/GPU124AMDCat1110PreDriverV3.aspx.
[support.amd.com] Just in case: remember, that by installing preview drivers you can damage your system and you're doing it only on your own risk.
Some features mentioned at the time of first preview's release:
"With today's launch of the Battlefield 3 early beta, AMD has released a preview build of their Catalyst 11.10 drivers specifically for Battlefield 3. The Catalyst 11.10 Preview driver improves BF3 performance on the Radeon HD 5000 and 6000 series for both single-GPU and CrossFire configurations, and adds support for 5x1 Eyefinity."
However, I don't know if it'll also include some improvements for Radeon HD 5xxxM/6xxxM..
Which cards do you use - ATI/AMD or any different? On which system do you work - x86 or x64? Which version of drivers do you use?
Ps. Yesterday I've noticed that the game crashes when I try to set gfx settings to Ultra (I've done this only for testing purposes).
Apart from this, I've managed to finish the entire campaign on "Auto" gfx mode (textures autmoatically set to "Ultra") with only one crash.. but after reading several threads, I should rather say "I'm a really lucky guy!" anyway ;)
