Image Quality - Performance
I've used UT2003, with our custom High Detail demo, to compare performance at the IQ settings that each card provides. I've missed out plotting the 6XS Go5700 mode for some commonality and ease of graph creation. The NVIDIA 8X MS+SS mode goes up against the ATI's 6X SGMS mode instead, with them being most comparable in terms of subjective quality. The 6XS mode scored 28.230 frames per second.Both GPUs share similar dropoffs in performance, until the NVIDIA GPU's super-sampling mode kicks in at 8X.
Some synthetic performance tests now.
