Higher quality != higher lag?

I just tested something with my video card. Normaly I play JK2 at 800x600 at medium quality and I get around 90fps. I change the resolution to 1600x1200, changed the quality to the very max then turned on aniso filtering (the in game option, not the display settings one) and I got around 60fps.

My computer is an AthlonXP 1700+ with FX5200 (non ultra) video card.


Today I was reading the latest article at anandtech and some benchmarks hit me as being weird.

In these benchmarks, Nvidia's NV38 got the same rate regardless of whether AA/AF was on or off. FX5900 was the same. Radeon 9800XT was pretty much the same. On the other hand, the Radeon 9600 Pro got slapped real hard when AA/AF was on. I'm assuming the FX5600 Ultra being faster with AA/AF than without is some sort of error.


How do these cards not slow down too much when the demand is increased so much?

The difference would be the 256bit pipeline. The R9600, FX5200, etc have 128bit pipes, so AA/AF squeezes it real fast.
