All of the games that we tried playing, over 12 titles in all, were retail games that we purchased with the most recent patches. In case you are wondering about pirated versions working on Vista we don't know because ours were legit. The purpose of this article was to see how the drivers from ATI and NVIDIA are doing and they are coming along. Neither are what we would call shipping-caliber as both companies lack a ton of features. The NVIDIA drivers don't offer overclocking, GPU temperature monitoring, SLI graphics and many other features that I would call required. I'm a gamer and if my games play ~20-30% faster on XP Professional then you wont see me switch operating systems till the DirectX 10 titles come rolling out.
