Next up, we tried some OpenGL
benchmarking with good ole Quake 3 Arena.
The two GeForce scores trounce
the Radeon by 30+ frames per second at every resolution.
While at first the Ti4200 seems to be keeping up with the Ti
4600, we have to mention that at this 1024x768, it is more
of a limitation of the CPU than the graphics card. When we
get up to 1600x1200, the Ti 4200 falls behind by 30 frames.
Regardless, who would complain about 115+ frames per second
at 1600X1200 resolution?
Anti-Aliasing
Tests:
The general trend continues when
we apply 2x and 4x anti-aliasing settings to get rid of the
jaggies. Even at 1280x1024 with 4xAA, however, we get a
respectable 50 fps out of Quake 3 with the GF4 Ti 4200.
Anisotropic
Filtering:
Finally it is the Radeons
moment in the sun. While neither GeForce card could come
close to the Radeons numbers when Anisotropic filtering is
enabled, they arent too far off from each other. We would
like to offer one caveat; GeForce cards and Radeon each
handle Anisotropic filtering differently, and a 32 or 64-tap
setting for one card is not exactly the same as the others
way of doing it.
In short, ATi has a selective process of super sampling
textures that are most visible to the user and not other
textures that wont benefit much from the filtering.
NVIDIAs approach on the other hand super samples the entire
scene and all textures. Image quality between the two
methods however is very similar and this is a subjective
topic of discussion that we wont get into here.
