Anisotropic performance hit?

[rogue1979]

I see all the benchmark tests and I see what some of the members post here. I have a Geforce 2 Pro and a couple of Radeon 32MB DDR's. When I enable anisotropic filtering to 16-tap I do not see a performance drop in 3DMark or any games. This doesn't seem normal, I tested several times and no difference. Looking at other people with comparable systems, my benchmarks seem on par with everybody else. Am I doing something wrong?

Are the early radeon's capable of 16tap? and are you sure it is being used within the tests?

I am using the 9050 for the Radeons, and the 23.12 for the Geforce Pro. Perhaps the anisotropic isn't supported or enabled?

i know some of the earlier drivers had broken AF...so even if you "enabled" it, it didn't really do anything

Yes, all Radeons are capable of 16x (128 tap) anisotropic filtering and all Radeons have a minimal performance hit when it's enabled. If in doubt, try enabling it in games and then looking for the increased image quality.

OTOH pre-GF3 cards are only capable of 2x (16 tap) anisotropic and have quite a large performance hit sometimes.
