Windows 7 vs Windows Vista ATI & NVIDIA Driver Performance

@ 2009/03/25

Whilst averages do get a kick, what's happening with minimums is more interesting, since often those were regarded as chinks in the 4870X2 dual-GPUed armor. We have a hunch about what's going on and why we're seeing these numbers, but we'd rather investigate further and have an educative exchange with the driver guys before detailing. At a glance, it would appear that the resource management part of the drivers has been overhauled/improved for Win 7, since more often than not, minimums were caused by resource swapping taking place.

results for XP and Vista are also changing , even now, so nothing new there either

Wasn't usually the case from past comparisons I looked at. Either way, it means the results are definitely going to change again regardless.

This is why it is premature to look at Windows 7 graphics performance just yet. Different codebase that is going to be changed yet again.

well i have not read the article yet. I hope the 64 bit systems are included, as we know how the drivers are not as good as the 32 bit XP/Vista etc.
