Doesn't this game have an ingame AA-option? The game also looks too dark, especially in the cut scenes. I'm using a radeon 3750.
For AA rename the executable in the "Binaries" folder from MassEffect2.exe to UT3.exe.
Then go to the CCC (Catalyst Control Panel) > Advanced > 3D > AA > Use Application Settings
Since it is based on the Unreal 3 Engine you can do this with ANY game based on it, including ME1 & ME2.

doesn't seem to work. how does renaming enable AA? is the AA in ut3 on by default? I can enable it in the ccc but it costs too much framerate. what about catalyst a.i., on or off?
Catalyst AI to Advanced (All Tab) and under the AA tab you can select the AA you want. The AA performance hit will be larger on HD3000 & HD2000 cards than on the HD4000 & HD5000 series.
It's not massively noticeable though, even at 8xAA, The Narrow Tent option does seem to look slightly better though. Catalyst 10.2 is most likely to have Mass Effect 2 profiles included but in 10.1 you will be able to modify profiles for the first time. If you look on the Rage3D forums you will find links to the 10.1 beta but it may be buggy so use at your own risk.
Unreal Engine 3 (UE3) uses a Deferred Rendering method that is incompatable with most AA which is why you have to force it. The next couple of Catalyst driver releases may make it much easier to get AA in UE3 games like ME2.
I don't get my ME2 until today/tomorrow (it's on the way already) but it works in ME1 with an old 4670 & a new 5850. Also, apologies for the long winded reply.
