Comanche 4
Comanche 4 is the next test to examine the cards' performance.
There's literally nothing between the cards at 1024x768x32. That's a sure-fire sign that the test is system limited, again.
There's not much of a loss incurred when placing heavy image enhancement into the mix. That's a testament to the architecture of the cards and the prominent role played by antialiasing and anisotropic filtering.
The trio close up again at the harshest of settings.
