Games are always late relases on Mac (well almost always), and I'm a pretty lagged player regarding new releases, but I finally finished Doom 3 today. I was running pretty well on my Intel iMac (20-inch, 2GHz CoreDuo, 2Gb, ATI X1600 256Mb) - steady 30+ fps at high details, 1024×768. Ultra-high requires 512Mb video RAM. Bloody hell… 512Megs.. :)
Since I'm really out of time lately, I tried to play several levels in a usual way, but in the end I have decided it takes too much time and also not very exciting so I just switched to god mode, gave myself full ammo, even clipping at higher levels ;) - and the game was done in I think 4-5 hours. Oh well I'm a happy camper again since I can concentrate on other things, without thinking about when I will have time to continue my descent to Doom's hell.
As for the game.. Aside for visuals, it's not very good. I'd say boring. Same stuff repackaged, same stupid enemies, almost no lights everywhere, and not my type of the game overall (I just hate these dungeon style maps..).
Looking forward for Quake 4 release for Mac on Feb 28th
