NVIDIA's drivers activate Alternate Frame Rendering when Halo is invoked to provide multi-GPU load balancing of the rendering workload. Here are the results we obtained from our testing with this game engine.
|For many gamers, the release of Halo marked the end of a long wait because it was originally released as an Xbox exclusive a few years back. No additional patches or tweaks are needed to benchmark with Halo, as Gearbox has included all of the necessary information in its Readme file. The Halo benchmark runs through four of the cut-scenes from the game, after which the average frame rate is recorded. We patched the game using the v1.05 patch and ran this benchmark twice, once at 1,280 x 1024 and then again at 1,600 x 1,200. Antialiasing doesn't work properly with Halo, so all of the tests below were run with antialiasing disabled.|
GeForce 6 series cards have a distinct performance advantage in general with Halo, but our SLI-enabled results speak for themselves again. The game engine is somewhat CPU limited, but the fastest SLI score is roughly 26% faster than the fastest single card score, at 1,280 x 1,024 resolution and 36% faster at 1,600 x 1,200. With SLI and Halo, 1+1 doesn't quite equal 2 in multi-GPU performance for NVIDIA and the ASUS motherboard, but it does equate to a hefty performance advantage nonetheless.
