Since Windows XP Pro 64-Bit was released, there has been a lot of speculation of whether it would help current gaming or anything else in general. I put both versions of the OS through a round of benchmarks to see if the 64-Bit does indeed offer any advantage.
In the next tests, I benchmarked two custom tests, in the C17 and Canals levels. Don’t pay attention to comparing the colors here, because they are seperate from each other, as they specify the resolution and nothing else.
The biggest differential here is in the Canals level at 1024*768, with an increase of 14FPS. Throughout all the tests though, the 64-Bit version of Windows made the game perform better.
For Doom III testing, I just used the built-in demo1 that everyone knows so well. The first run on each resolution was ignored, and the score from the second and third runs were averaged out to get the final FPS. There is virtual no real performance increase here, although it is still better, albeit slightly.
