Later this year Microsoft will release its next major desktop operating system, Windows 7. After deciding now was the time to expand my hard drives (because I really need 3TBs of space), I took the opportunity to install the "release candidate." The release candidate of Windows 7 is just that -- it's a version of the operating system that while still in development, has all the bells and whistles, and is essentially the exact same thing that'll be sold on the shelves.
The installation and configuration of Windows 7 went very smoothly. For the technically inclined, my computer has four gigs of RAM and operates off of two dual-core Intel Core2 processors. I have an nVidia GTX 260 graphics card, which is the latest generation. There's a bunch of other bells and whistles that I have as well, but those are the big things relevant to what I do every day here at WoW.com and how I play WoW.
Prior to installing Windows 7, I used Windows Vista updated to the latest patches. I got about 60 FPS on average, with a maximum of around 100 while idling in some far off place with not a lot of traffic; and a minimum of about 50 while in some of the more graphic intensive raids / battlegrounds. After installing Windows 7 I was running at about 75 FPS average, with a maximum still of around 100. However more importantly my FPS during raids / Wintergrasp shot up to 70.
