can I play this with a 8600gt at 1280x1024?

can one  

hey, u can force AA via ur nvidia's control panel 

i'm playing at 1440x900 with c2d e6600 2.4ghz, 2gb ram, 256mb x1950pro...everything max running quite nicely. really optimized for mid-range pc. even tom clancy rainbow las vegas which also uses unreal engine cannot max the graphics option for a playable fps.

What sort of FPS would I expect?

care to elaborate? btw.. i was gogling some stuff up and i seem to find loads of therad saying when AA is enabled there are plenty of graphical corruption. such as dark area becoming light and testures not loading properly

has any of u guys experience this.

By default BioShock does not support any Antialiasing (AA) to smooth out jagged lines. The reason the game doesn't support AA natively is because it uses a form of rendering called Deferred Lighting, which is supposed to be incompatible with Antialiasing in DX9. It may be possible to allow AA under DX10 according to the developers of the Unreal Engine 3, but this will likely require a patch and if this occurs I will update this section accordingly. In any case If these 'jaggies' bother you, you can attempt to force AA to be applied in Bioshock, though note that you will experience a decrease in performance, and you may experience graphical glitches. The procedure is not completely straightforward, so read the following to determine how to do it for your system:

# Antialiasing can only be forced in BioShock through the graphics card control panel in both Windows XP and Windows Vista, but only in DX9 mode, not in DX10, and also only on GeForce 8 or ATI X1X00 series cards or newer. Note that in Vista, "proper" DX9 mode will have to forced via the -DX9 switch (See DirectX 10 Detail Surfaces further below for the reason).

# For Nvidia users, make sure to use the 163.44 Forceware or newer which are specifically designed for BioShock compatibility. In Windows XP you can force AA through the Forceware Control Panel as normal, but in Windows Vista you will need to go to the \Program Files\2K Games\BioShock\Builds\Release directory and rename the BioShock.exe to R6Vegas_Game.exe. Then right-click on your BioShock launch icon, select Properties and in the Target box add -dx9 one space after the end of the line and click OK. It should look something like this:

"E:\Program Files\2K Games\BioShock\Builds\Release\R6Vegas_Game.exe" -dx9

# For ATI users, you can only force AA in XP or Vista if you rename your Bioshock.exe file to Oblivion.exe, make sure Catalyst AI is activated in your Catalyst Control Center, and then right-click on your BioShock launch icon, select Properties and in the Target box add -dx9 one space after the end of the line and click OK, similar to the example above.
