between my WinXPpro 32 bit partiton and my Windows 7 Ultimate 64 bit partition, the Windows 7 Ultimate 64 bit completely blows away windowsXPpro....it gives my LCD monitor screen rez 5 more frames over WinXP
winXPpro- monitor max screen rez using 1280x1024 = 70 mhz
Win7Ultimate 64bit- monitor max screen rez using 1280x1024 = 75 mhz
windows 7 Ultimate lets me utilize my total 4 gigs of ram
windows 7 ultimate 64bit, Ah2 never sees a hicup and stays pegged with detail set to the new 4 miles, and all other graphic detail settings maxed out using 1280x1024 screen rez and the hires texture package
in winxppro 32 bit..when smooth shadow is enabled I experience a loss of 30 to 40 fps....not so in win7 ultimate........
I have it set up in a dual boot configuration , using the same computer for both OS installations

-Note one of the 320 gig HD's ( my main one I am using most often is partitioned as a Dual Boot with 2 OS's as follows:
1st HD partition has Windows XP Professional SP3 32 bit
2nd HD Partition has Windows 7 Ultimate 64bit (Enterprise MSDN Technet Legal Copy)
thru all the recent patches and new AH versions, I only experienced 1 problem in Windows 7, for some reason which might have been my mistake to begin with, it picked up my onboard HD audio, my Video Card HD audio and my Sound Blaster Fatality Extreme Gamer Professional Sound Card and they were all enabled at the same time, which caused my mic not to work in game..I noticed though it did the same thing on the Windows XPpro partition as well....a quick disabling of the Video HD audio and the Onboard HD audio fixed my mic issue I was having.......
in windows XP pro I experienced a few warps/stutters in I think patch 6 and patch 7........have not experienced anything of the like in windows7 OS.....
outside of the arena wide disco's/game freeze alot of us had back during the last Scenario and one of the FSO's.........
as Ghosth's posted,, I agree that Vista may take more hardware to experience the same or close to same as xp, but I disagree that Win7 will require more.........my personal experience has showed me Windows 7 utilizes a persons PC setup/hardware far better than WinXP does........
I have tested/checked out and used WIndows 7 since around November/Dec of last year, and in my view Windows 7 has been near Rock Solid since they released the Windows 7 RC candidate back in May of this year.......
YMMV.......
