Lost Planet Performance
Since we are evaluating a DirectX 10 video card, the use of Windows Vista is a definite requirement, but we also need some updated DirectX 10 game benchmarks as well. One of the best is the Lost Planet performance test, which comes in both DirectX 9 and 10 flavors, which allow across-the-board comparisons against last-generation graphics cards. The benchmark is also extremely tough on the hardware, and the resultant scores can be quite hard on the mainstream graphics cards, showing unplayable framerates in many cases. Since this is a high-end DirectX 9/10 game benchmark, we've utilized widescreen resolutions from the start, choosing 1600x1000 and 1920x1200.
To say that Lost Planet is a demanding game benchmark would be the understatement of the year, as you can almost hear the system grinding as it completes the testing. The Gigabyte Radeon HD 3870 512MB does very well in this benchmark, and scores right on par with the GeForce 8800 GT and Radeon HD 2900 XT 512MB cards, and just back of the powerful GeForce 8800 GTS 512MB.
Lost Planet AA and AF Performance
Upgrading the already tough Lost Planet benchmark to 4X anti-aliasing and 16X anisotropic filtering yields another very brutal gaming environment, and all the scores drop a bit. We see the Gigabyte Radeon HD 3870 card do very well initially, before falling back a bit at 1920x1200.
Supreme Commander Performance
Supreme Commander is a high-end real-time strategy game, similar to a next-gen Total Annihilation, which combines killer graphics with top-level AI. The in-game visuals are incredible, and when there are multiple armored mechs in the same area, it can take a real toll on even high-end system configurations. This makes it a great benchmark for our high-end graphic cards, and while the in-game benchmarking program offers several different performance ratings, but for this market segment, we prefer the overall FPS score.
The Gigabyte Radeon HD 3870 does well on the Supreme Commander benchmarking, outpacing the Radeon HD 2900 XT, but is still not able to match the GeForce 8800-based 512MB cards.
Supreme Commander AA and AF Widescreen Performance
It's virtually the same story at the widescreen resolutions + anisotropic filtering and anti-aliasing settings, and the GeForce 8800 GT and GTS cards are still the class of this particular benchmark.
