Well my first impression: WOW! Scarey! Alone in the dark the sounds and lighting are quite spooky.... The G7 With Radeon Z950 (ships when the X800 comes as a stock card from apple replaginy the Y900 which replaced the 9600XT) will suit this game well! Sigh - after being a poster child for the positive... my 2+ hours on this game are impressed but dissapointed. While my Mac is top of the line it was not bought for games - but I admit I was really looking forward to the bragging rights it would give me with Doom 3. For starters - there are screen 'jutters' even on 800 X 600 High settings no AA. Door openings in coradoors seem to be the big culpret. There is NO support for 5.1 optical sound - the game proudly boast this will be supported in future patches. There is NO support for the wide screen format on my Apple 23 inch screen - well at least not on any of the resolutions I tried (all of them to the best of my knowledge) But I admit I will continue to play it even though I know I have to choke down the fact that I'm only getting 50 to 60% of the graphics potential and that nothing I can do short of buying a windows machine will help that. It will probably get shelved like Warcraft III did til I bought my G5 (old b/w G3 did not bode that one well). Then in a few years... My big question is WAHT hardware did they use to test this on? Someone had to test 1600 X 1200 on 16X FSAA and Ultra settings... my guess it was 'Da New Guy' - give the rookie this job.... So that is my first take of Doom 3 on my 'wussy' system. Drivers? 10.4? or a G7. All of these will probably help this game out. Iriejedi PS - I did pick up Tron 2.0 for $9.99 at Comp USA - an amazingly fun game for under $10!
