Benchmark Results: DirectX 10 For Nvidia 3D Vision LCD Glasses
Let's have a look at the performance impact of choosing the DirectX 10 version of the game. Remember, the only advantage that DirectX 10 offers with Resident Evil 5 is the ability to use Nvidia's GeForce 3D Vision LCD glasses, so there's no need to benchmark the Radeon cards--the glasses only work with Nvidia cards.
Fortunately, for GeForce 3D Vision users, the performance impact is extremely minimal.
Editor's Note: Bear in mind that running in DirectX 10 mode is simply a requisite for GeForce 3D Vision compatibility. You can't actually use the feature until it's enabled in your driver panel. And, at that point, you're looking at a much more pointed performance impact than what we've seen here.
With a Core i5-750 machine armed with one GeForce GTX 260, we got 76.2 frames per second at 1680x1050, all details set to high, and 4xAA enabled. Turning on GeForce 3D Vision yielded a drop to 34.8 frames per second. So, if you're looking to actually play the game with GeForce 3D Vision, your safest bet is to divide any of the results above by two. Clearly, running high resolutions with lofty settings and an immediate halving of performance is going to require serious graphics horsepower--more than the GeForce GTX 260 tested here is able to provide.
