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."
Sounds like they are simply re-compiling with a new tool chain; nothing about actually changing the code base to take specific advantage of Opteron features. Still, kudos to their coders if their code base just works on 64 bit platforms; there'll be plenty out there that won't, despite availability of the SDKs and programming guides like this and this

32 bit x86 code will run natively and just fine on x86-64 systems. You're getting confused by how IA-64 runs x86-32 software.
x86-64 also supports SSE2, fyi. That link's a giant x86-64 FAQ.
x86-64 also gives you another chunk of architectural registers that the programmer/compiler can use. I'm sure this contributes to the jump in performance that is claimed along with the on-chip memory controller.

Yeah, but there's a lot of code out there that makes hidden assumptions about 32-bitness. This code acts up when you compile it for 64-bit architectures.
Immediately after Half Life came out, Valve were working on Team Fortress. After that was released, they continued releasing patches for the game. A bit later, they adopted CounterStrike and "helped" with some changes in the game, such as the new animations and netcode.
It's been leaked at some news sources such as www.ve3d.com that Valve are currently busy with Half-Life 2. One of the general theories out there is that this Half Life will have Team Fortress 2 included, or at least integrated with HL2. Most of us are also assuming that Valve has changed engines for the new games or are basically building their own.
At any rate, they're working on something, they're just taking their sweet time with it and not releasing any information about it. They've probably learned a thing or two from Duke Nukem Forever.
I run the servers for a washington D.C ~200+ player lanparty Capitol Punishment, and I know that we could use this kind of hardware. At the moment, we have to split our 10player counter-strike cs servers between at least 2 dual cpu boxes w/ scsi etc to excellent performance on lan. I know what I'm talking about, we are coming up on our 6th. Add to this various addons like adminmod, or in our events case, the wwcl plugin to make sure people arent abusing console variables, and you quickly need more horsepower to keep the pings low, and the choke low, so on and so forth.
To some it doesn't matter, but in a competitive environment, you want the fastest shit you can find. And spreading that across 2-4 boxes makes management a bitch. Not mentioning other servers for other games being run at the same time.
Now, the funny question, is what is the CPL going to do, since it's an Intel sponsored event. Although I won't disagree that some dual 3ghz+ xeon servers w/ scsi and dual channel ddr don't already make great game servers for my needs.

Hypothetically, you could use 64-bit integers to repleace floating point numbers in many places (think physics engines, graphics calculations, etc). You wouldn't have the same accuracy that you would get from using floats, but it's a nice middle-ground between 32-bit ints, floats, and double-precision floats. Generally speaking, dealing with integers is much faster than dealing with floats.
