DOOM 3 performance

Notes
Once ATI’s hotfix driver is installed, the RADEON X1800’s performance dramatically improves in DOOM 3. At 1024x768 with 4xAA/8xAF, the X1800 XT saw a performance improvement of 16%, while the XL board’s performance was improved by 15%. By the time the screen resolution is increased to 1600x1200, the progression is even more significant, with the X1800 XT running 28% faster once ATI’s hotfix driver is installed, while the XL card sees a 20% improvement.
Altogether, these improvements are astounding – this is the type of performance improvement you expect in a new product, not a driver release. The scary part is these are only ATI’s initial changes, they’ve acknowledged that there’s still room for further tweaking.
DOOM 3 is a game that’s been out for awhile though, the real question is, how does the new hotfix affect performance in a brand new OpenGL title like Quake 4? Let’s find out.
But is this enough for the RADEON X1800 XT/X1800 XL to overtake the GeForce 7800 GTX and 7800 GT in performance? Let's find out !
