NVIDIA Windows Vista Forceware enables 16xAA wrongly for 8800 in some games

It has been found that some games running under Windows Vista enable 16x coverage sampling anti-aliasing (CSAA) when 4xAA is selected in the game menu, resulting in deflated performance on Geforce 8800 cards. The problem occurs with NVIDIA Vista drivers 100.54 and later. The same effect will occur in future “Release 100” Windows XP drivers. Affected applications found to date include Battlefield 2, Battlefield 2142, Sin Episodes, Half-Life 2 and Half-Life 2 Lost Coast.

games running under Windows Vista enable 16x coverage sampling anti-aliasing (CSAA) when 4xAA is selected in the game menu,
resulting in deflated performance on Geforce 8800 cards. The problem occurs
with NVIDIA Vista drivers 100.54 and later. The same effect will
occur in future "Release 100" Windows XP drivers.

Affected applications
found to date include:

Battlefield 2

Battlefield 2142

Sin Episodes
Half-Life 2
Half-Life 2 Lost Coast

To set standard 4xAA
in these applications, set 4xAA in the game, and also enable
“Enhance the application” anti-aliasing mode with a 4x anti-aliasing
setting in the NVIDIA graphics driver control panel.
NVIDIA is working with
developers to implement better in-game CSAA support. You can see
CSAA menu selections in Half-Life 2: Episode One and Supreme
Commander.
