All of the newer games I used supported 1440x900, or I forced them into that resolution by using custom parameters. This is not an issue, as they run fine in XP under 1920x1200, a much higher resolution. As for the older games, most of them were in 1024x768, as a lot of them don't have options for custom resolutions. Even so, they still performed better at 1600x1200 under XP than 1024x768 on Vista.
Hmm... I was just about to order Vista, but you make me unsure!!!
Anyone else got such bad exp. with Vista under Bootcamp?
