I can only conclude processor management has been improved, and that’s the only area in which it performs better (on average) than it’s predecessor. However, on the graphics field, it seems Windows 7 is even more demanding on the graphics card. An important remark is these tests are taken with the first Beta build of Windows 7 against Service Pack 1 for Vista, so these values might be more improved in the final version.

Though I must say, Windows 7 did seem very responsive in my test, and I’ve heard good things about it’s performance on lower end systems. I think it’s safe to assume that a pc that runs Vista will run Windows 7 equally well. Also, while gaming, I’ve barely noticed a difference in framerate between Windows Vista and Windows 7. I guess we’ll just have to wait and see what the future brings.
