Those amd-optimized binaries weren't 64-bit binaries AFAIK (this is from before I started working on the linux ds), but rather were just binaries produced with gcc tuning settings set to favor the amd64 chips. With the orange box (and subsequently with l4d), we changed a lot of our compiler settings and versions and a lot of things about the way we optimize code had changed, and it was felt that after these changes, there weren't significant improvements from having separate binaries for intel and amd.
In our more recent dedicated server work, we've concentrated on optimizations that enhance performance of all platforms, and you can see it in the left4dead linux ds. This release had a lot of the linux-specific code rewritten, switch compiler versions, turned on higher optimization levels, and had a lot of linux-specific server features added, and is definitely the highest performing linux ds we've released for any of our games. -----Original Message----- From: hlds_linux-boun...@list.valvesoftware.com [mailto:hlds_linux-boun...@list.valvesoftware.com] On Behalf Of ics Sent: Saturday, January 24, 2009 11:47 AM To: Half-Life dedicated Linux server mailing list Subject: Re: [hlds_linux] AMD64 binaries Maybe 64bit binary was discontinued because it was harder to keep up many branches of the engine. Srcds_i486 runs fine on most machines. Thats the main purpose anyway, not "best performance" which some people here seem to be looking for. Their agenda may be commercial or out of interest but i dont think you will get 64bit binaries unless whole Steam goes 64bit among games. It must be discontinued for a reason. -ics Walton Hoops kirjoitti: > I admit I haven't dug into the scripts to see what is actually being run, > but whenever I start my server (using Ubuntu x64), I see: > > Auto detecting CPU > Using AMD-Opteron (64 bit) Optimised binary. > > This sounds to me like there already is a 64-bit binary.
