Gon i know what Hardware t&l is btw Transformation & Lighting.
Well about on consoles they are 1 spec for each so they can optimize grafix and code for but then they have to worry about low memory and then too they are on the market for years.Example look at deus Ex 1 (i think its for mac too)The maps where pretty big looked not to bad for its age and used Unreal Torament engine and it was built for the pc.Deus Ex 2 was built for the xbox and it used a heavly modified Unreal warfare engine,looked pretty darn good over the frist one but then there was the small maps because of it working with less than 60mb of ram.Same thing with thief 3 small maps.When there selling games for mac/pc they gotta think about what does most of the market that would buy this have avg ram,avg video card,avg cpu.So givin that there is they gotta have modes like doom3 and hl2 or just 1 mode and pick what user system to make it for low,mid,high.
Doom 3 on mac is prime example where there targeting the market and hardware right now so far with the demo as it looks u lucky ppl with dual g5 1.8 and up with x800 or 6800ddl/GT be able to play it and anyone that has a new imac possably upriver without a paddle and the upper G4 users your worst off than the imac G5 users.
I know there more work to be done for doom 3 on mac.
Its the same with your's mac's its a control platform with 1 chipset maker,motherboard maker and even apple controls video drivers.With the software u have is optimize too the teeth or getting there.Pc market has many chipset makers,audio,ati,nv,3dlabs,etc. then there hardware makers the list goes on and it is a hard platform to control.Even with MS flaws it does not a bad job keeping all that hardware/software goin but is not always easy.
sunilraman u shouldn't throw stones at glass houses u know giving the fact the only way g5 got to 2.5ghz atm is because of water cooling.http://arstechnica.com/reviews/hardware/G5.ars/1
The bottom of the page he says the temp and u ppl that have this system post your temps to prove me incorrect.i would like to be proved wrong about it.
This is not to flame but with temps like that with water cooling the would of been no way in u know where apple could of done it with what they do with the dual 2ghz.
