Scroll down to 4/29/00 and Carmack explains exactly why we need 64bit color(far too lengthy to cut and paste here).
Unreal/UT looking better in different APIs- Epic svcks. That's pretty much the whole thing, they are absolutely horrible at making games. Unreal is how old now and the thing still only runs properly in Glide. Horribly broken after years of time to patch it. I refuse to buy UT until I can play Unreal properly on a non Voodoo board. OpenGL is the ugliest mode, that is for sure, but it also plays the smoothest on my DDR or TNT(hardly any difference whatsoever) by a wide margin. Flyby only averages in the 40FPS range versus high 50s with D3D, but none of the Epic type gameplay(very slow and jerky, unbalanced and headache inducing). They need to hire people who can write better code then what they have now. My current rig is significantly faster then the best available when Unreal shipped and the game still doesn't run at what is associated with playable FPS. Epic svcks, and badly at that.
"Oh OT - yeah 9x is 16 bit program that runs on Dos which is 8 bit base code"
DOS is 16bit, Win9X is 32bit. Windows is not a program, it is an OS. Win9X still has plenty of 16bit code, but it is not a program that runs on top of DOS.
PC gaming won't be dead in a year, it never has been alive. I think that is something most people don't realize, PC gaming always has been and more then likely always will be a very small niche market. Consoles have owned the gaming market since the beginning, most PC gamers are just blind to the fact. More developers going console? They don't need any and it is highly unlikely that they want any outside of a very small handful(Blizzard, id, Valve etc, only the best). Most PC developers would be laughed out of the market after their first release. PC gamers are used to dealing with third class buggy software, console users have much higher standards and would not tollerate such things. PC gaming will survive, and I doubt too many will jump ship to consoles, it is a completely different type of environment, people worried about having fun over supporting the latest features and such, gameplay over useless complexity. As PC gamers we see things differently, but we are a 
very small market in comparison.
