SLI AA & AF - HL2: Episode One & Riddick
Half-Life 2: Episode One
These images are unresized 1920x1200 each, showing you the image quality difference between 0xAF/AA, 8xAF/8xS AF & 16xAF/16xS AA
Setting the 16x settings in Half-Life 2: Episode One resulted in a ~45% drop at every resolution. In other words, the game was very consistent and remains barely playable at 1680x1050 with the SLI AF & AA enabled.
Chronicles of Riddick
These images are unresized 1920x1200 each, showing you the image quality difference between 0xAF/AA, 8xAF/8xS AF & 16xAF/16xS AA
The drop in Chronicles of Riddick was around 50% across all resolutions, but only the lowest, 1280x1024 remains playable at these settings.
