At the maximum detail setting, we are treated to shadows and 4x anti-aliasing (AA). Let’s see how this affects performance:
We're not seeing 100+ FPS anymore, that's for sure. This setting cripples most of the graphics cards, and it's likely due to the stress of calculating shadows for scores of asteroids. The Radeon HD 4650 is unplayable at this level of detail, and the GeForce 9600 GT can just handle 1280x1024. Even the Radeon HD 4850 can only reach 1680x1050. For the newer Radeon HD 5770, this resolution might be considered playable, but it is providing less than the ideal 30 FPS we'd like to see.
At 1920x1200, the playing field is reduced to the GeForce GTS 250 and GTX 260, while the Radeon HD 4890 and 5850 hang in there, too. Once again, we're seeing the GeForces stand up well to the Radeon competition.
At 2560x1600, none of these cards are playable. The GeForce GTX 260 might be passable for folks who can accept 25 FPS, but it's not something with which I'd be happy.
