Transparency Antialiasing Quality

We took screenshots in two popular shooters, Far Cry and Half-Life, to see the effect of the new full-screen antialiasing methods.

no FSAA	no FSAA
FSAA 4xS + TMS	FSAA 4x
FSAA 4xS + TSS
FSAA 8xS + TMS	FSAA 6x
FSAA 8xS + TSS

Alas, we couldn?t find any great differences between ordinary FSAA and FSAA with enabled Transparency Antialiasing in Far Cry. Well, yes, there is a difference, but it is so negligible that you can notice it only after a careful examination of each screenshot.

Half-Life 2 is quite another story: Transparency Antialiasing makes the image much better in this game. We mean the Supersampling mode, while the Multisampling mode brings a less impressive picture, even though of an improved quality, especially in combination with FSAA 8xS. The most beautiful picture can be observed in FSAA 8xS + Transparency Supersampling mode: even the smallest details are drawn almost ideally. So, the new feature of the GeForce 7800 GTX ?Transparency Antialiasing ?can really improve the quality of certain details of the image, especially if combined with FSAA 8xS, but how does it tell on the speed of the card?
