More on 64-bit Gaming

waytoomuchcoffee writes "Valve has announced "immediate availability" of a linux 64-bit dedicated Counterstrike server, designed to run on AMD's upcoming Opteron. This follows on the heels of Unreal Tournament 2003, previously reported on Slashdot. Gamespy has a related story up on a presentation of the future of 64-bit gaming (sponsored by AMD) at last week's Game Developers Conference. As Intel is in no hurry to make the jump to 64-bit desktops, this leaves AMD to court the gaming market."

      it's a nice middle-ground between 32-bit ints, floats, and double-precision floats

      Absolutely wrong. Anything that is going to be scaled or rotated (think matrix transformations, vector multiplication, and physics calculations) needs to have floating point representation, unless the processor architecture is incapable of it (the Gameboy Advance or other embedded platforms, say). You can have pseudo floating point with ints (last x bits are behind the decimal, say), but the software needs to do extra work: there's special cases for multiplication, etc. Most processors these days are designed to do floating point operations as fast as anything else, so adding unnecessary overhead that ignores basic funtionality would be stupid.

      If you have a 64-bit cpu, use 64-bit floats instead of 32. 64-bit floats are superior for games because of increased dynamic range for lighting (less color banding with scaling) and other values, and of course less floating point round-off errors (less matrix drift).

      Game servers do no graphical calculations, so there's no advantage there, but some of the physics could be done centrally to prevent the clients from making up their own and cheating.
