ATi Radeon 4000 Series Anti-Aliasing Investigation
In a past article, I compared the image quality of ATi’s and nVidia’s latest hardware, but since there’s a lot left to cover with each vendor’s anti-aliasing, I decided to investigate the issue further.
This article will focus on the ATi 4000 series of cards (whose anti-aliasing algorithms are identical to that of the 2000 and 3000 series), while a future installment will cover current nVidia hardware. For this particular article I will use my trusty Radeon 4850.
