Doom 3
AFR mode is the default for Doom 3 again with 6600 GT in AFR mode. Benchmarks are done in High Quality and Ultra Quality modes.High Quality
At the initial setting without anti-aliasing, the pair of 6600 GTs match a single 6800 Ultra for speed. Thereafter however, they fall back to match a single 6800 GT. I'll examine the performance increases in more detail soon.
In the Ultra quality mode, with uncompressed normal maps abound, initial performance is excellent, outstripping the single 6800 Ultra without issue. A subsequent settings, it matches or slightly lags behind a single 6800 GT. The framebuffer size of the boards, and their memory interface, conspires against them in that race for GT or Ultra-matching performance.
