I decided just for the heck of it id install Vista on a small partition on my hdd in my gaming rig. here are some specs. AMD Athlon 64 X2 2.0>2.5Ghz 1Gb Trancsend PC5400 DDR2 667Mhz 1x Maxtor 40Gb (WinXP) 1x Samsung 80Gb (Parttioned to 60Gb and 14.5Gb, vista on 14gb partition) ATI Radeon X700 Pro (upgrading, buts its till a decent card, Runs aero perfectly) Well for this test i ran rollercoaster tycoon 3, Americas army, and rome tw. I also benchmarked with 3dMark01. Heres the results: RCT 3: XP: Graphics Auto set at Very High Vista: High (wtf? same hardware) AA: XP: Auto set to High Vista: Auto set to Med. Rome TW: XP:Auto set to High Vista: Same 3DMark01: XP:12,000 3DMarks Vista: 14,000 3DMarks So im confused i get better 3DMarks under Vista, but Better graphics performance under XP. I even mixed it up a bit and mached graphics setting to the way they are in xp and the games performed horribly under Vista. So this kinda confuses me, but also proved performance suffers under Vista.
