In order for anti-aliasing to work, geometry gets scaled up to double their resolution in GPU memory. An old card, running at 1080p with anti-aliasing is absurd.. It was never done then, and no gamer is going to do it now on an old card because the framerates produced are too low to be playable and it has nothing to do with the GPU chip or the driver.
What are you on about? Oh really? Then why where these cards tested with games like Quake 4 on ultra with 4xAA and 16xAF @ 2048x1536 and still managed to get playable framerates? http://www.firingsquad.com/hardware/...0xtx/page7.asp You always max out everything you can when benchmarking as you are again maxing out the card and driver's abilities. If the case of this old Radeon hardware we KNOW what the hardware is capable of, so what we're seeing with these tests is what the Gallium3D drivers are capable of making the card do since we are still far off from what the hardware is known to be capable of.

The vast majority will run the game at their LCD's native resolution with all settings maxed that they can get away with before looking at what they can do with AA settings. your goal with AA is to reduce jagged edges, if you are lowering the resolution and using lower detail levels on the textures then even with AA turned up it's going to look like crap.

Performance tuning though would be playing with the settings of the usual biggest performance impactors like soft shadows, dynamic lighting and AA settings since AF settings are almost free on GPUs from the last 5-6 years.
