→Debunking the Myth (glxgears is a benchmark)
Your FPS numbers went up/down after you loaded the latest version! This is not because there was a change in the driver. Since the program is so wild and sensitive to load (since it barely uses any computational power), any 100+ FPS increase or decrease can easily be attributed to a music program or OpenOffice document you have open. You can also wildy change FPS in glxgears by simply unfocusing the window. Want a 1000FPS increase?? UNFOCUS THE WINDOW! Of course this is meaningless, since you can't enjoy Doom3 if you can't see the window.
