Benchmark Results: 3DMark Vantage
To begin, 3DMark Vantage, which is a qualified application in all five supported rendering modes, demonstrates a Radeon HD 5870 and GeForce GTX 285 cooperatively generating lower scores than a Radeon HD 5870 on its own.
On the other hand, in A-mode, Lucid is able to achieve better scaling than CrossFire with a pair of Radeon HD 5870s in two of the three benchmark presets.
Then the reverse holds true in N-mode, where SLI on Asus’ P55-based platform consistently outruns the Hydra solution.
We bucked tradition and left the PPU option enabled for these tests, hoping that the GeForce card would be recognized in the CPU suite and used to compute PhysX-based optimizations in the benchmark. Unfortunately, when you follow guidance and use the ATI card in PCIe x16 slot one, you can’t even bring up the Nvidia driver control panel—much less employ PhysX in 3DMark Vantage. This is a known issue, according to Lucid, and being looked at currently.
