Actually NTSC tv's have a screen refresh rate of 60hz so games can run at 60fps, NTSC and Pal TV programs are broadcast at 24-30fps. Pal tv's have a screen refresh rate of 50hz and therefore can display only 50fps. But then theres Pal60 which runs at 60hz as with ntsc. Pal video is also of a higher resolution to NTSC vertically, something like 50 lines or something. Look at PC monitors, you be using a resolution of 1024x768 at 100hz and still get 200FPS ins some games. The monitor however cant display all of the frames and thats why you get occasions where one half of the screen seems to be out of line with the other. Thats where V-sync comes in. This limits the FPS to the monitors refresh rate so if its at 100hz you will only get 100fps and the image tearing stops.

Also, Doom 3 could well be just as good as the PC version graphically and just as smooth since the game will be re-written to take advantage of the hardware. The pc version will never be optimised as much as a console version due to the vast amounts of different PC configurations. ID have to contend with different CPU's, Memory, Mobo Chipsets, GFX and Sound cards, operating systems, to name a few. The problem they have is that they have to get the game to run on ALL hardware so its impossible to have it running optimally on each of them. With the XBOX version however they only have 1 set of hardware to concentrate on, so all their time can go onto optimising the game for that hardware. I cant see how a PS2 version will be possible though. Its a powerful machine but there just isnt the memory for the game without sacrificing shed loads of GFX quality. As for the gamecube, i'm pretty sure it could be possible but not as nice as the XBOX version.
Cant wait to find out though =D

MS today confirmed that more than 149,000 users have been blocked from the Live service. A spokesman for Microsoft said "Xbox Live Launch has been a complete success. Our plan to scam a further $50 from modchip owners has worked flawlessly. We hope to have another 300,000 Live starter kits ready for monday to cope with demand and to meet our target of 1,000,000 xboxes banned by christmas"
