Even without AA/AF, turning on the “Optimize for SLI” setting brought immediate performance benefits to both the NVIDIA, and even ATI cards. At 800x600 alone we saw a 15% performance improvement for both the GeForce 6800 GS, RADEON X1600 XT and RADEON X800 XL, while GeForce 6600 GT’s performance improved by 13% at the same resolution. The margins begin to tighten up though once the resolution is increased.

Notes
Once again we saw tangible performance improvements by turning on the SLI setting, even though we’re running single-card configs here. You’ll see the best improvement at lower resolutions though.
