Your Graphics Card Sucks
I know that there are plenty of people out there that will vouch against what I am about to say, so if you are one of those, feel free to leave your thoughts in the comments.
While running Windows XP Professional, my graphics card performed as a Radeon 9800 Pro (I actually have an ATI Radeon 9800se – the card that ATI knows nothing about). Thanks to a software modification, I was able to have my Radeon 9800se function as a Radeon 9800 Pro, and boy what a difference did it make! Staggering frame rates in all my games, including Half Life 2 and associated games! Needless to say, I was happy I had been a cheap skate, and bought the 9800se from eBay. Up until installing Windows Vista Ultimate, and a couple of games, my 9800se reborn, was “the ownage” in my little world. Come now the days of my Windows Vista adventure, and my 9800se reborn, plays games the same games like a 16MB Voodoo 2.
In other words, my graphics card now totally SUCKS the big one!!!1111. Even though I downloaded the Vista software modification, the resulting increase in performance was only that of a slight percentage, and for the first time (in regards to my graphics card), it caused my system to become unstable, and even blue screen! Yes! Vista has blue screens!
It seems that Windows Vista, really claims a lot of your video memory, just to run Windows, especially with Windows Aero enabled. Which is interesting, considering the same effects, in fact, even cooler and better effects, can be run on a 16MB voodoo 2, on a machine running Fedora 7, with Beryl/Compiz installed.
