Comanche 4	Source: Novalogic

The Comanche 4 benchmark demo is a unique test as it represents a real-world gaming experience. It contains the single player "Eagle's Talon" mission from the game as well as a detailed cinematic. This DirectX 8.1 benchmark demo will measure your system's performance in the standard frames per second format. The benchmark was run with audio disabled.

Epox 8NPA SLI (NF4 SLI 200/400 7800GTX SLI)	65.65

Comanche 4 does not put the Epox 8NPA SLI motherboard in a good light and SLI degrades performance all around.

X2: The Threat	Source: Egosoft

A completely rewritten 3D engine based on DirectX8 encompasses many visual effects such as volumetric Nebulae (gas clouds) that have a real impact in the game (you can hide in them) and many new engine, shield, weapon and explosion effects. Objects cast real dynamic 3D shadows! Dynamic DP3 bump mapping allows a previously unseen level of detail.

It is rather surprising to see SLI drop the X2: The Threat frame rate so much, the benchmark was rerun a few times with the same results.
