64 bit processors

[Crix]

Will Doom3 benefit from the Clawhammer's 64 bit capability. I mean to say, will the Doom code need to be written in a certain way to make use of the new chip architecture or is that unnecessary? I'm gonna hold out for a ~2.5Ghz x86-64 Clawhammer with .13micron die. I'd like the .09 but that's second half 2003. May be too pricey still.

Carmack has stated there is not likely to be a 64 bit executable for DOOM III, as it would generally have worse performance than the 32 bit executable.

Umm, I think that should be lower performance.

[Mastaba]

Well, isn't lower performance tantamount to worse performance?

[Lord FlatHead]

Well yes, but saying worse implies that the 32 bit exe was already bad. Nevermind.

[Crix]

huh, that's interesting. I wonder if a 16 bit executable would run doom faster. Then again, I don't know much about how this stuff works.

I think you'd probably have difficulty making a Doom 3 executable.

So no.

/me renames Doom2.exe to Doom3.exe
I MADE A DOOM 3 EXECUTABLE? I didn't? Oh, Goddamnit!
/me mutters and walks away

They're having that in mind for the planned SNES port.

Oooooooo, GOODy!

Isn't the dos Legacy executable named doom3.exe?

Yes it is, for some reason (that I can't understand).. :/

[Psyonisis]

Isn't it weird that doom legacy uses doom3.wad, AND Legacy was the name of the video that was released?! for doom 3?!

Doom is 32 bit and always has been. Thats what DOS/4GW (you see the splash screen for it when you start up doom) does.

LOL!!! Hm.. that would be cool though.

Speaking of which, how's the Doom2D game coming along?
