In other news, Valve has delivered to the world 64-bit versions of Half-Life 2 and Lost Coast via its Steam content delivery system. This development is obviously prompted by AMD, whose Athlon 64 FX processors are pimped in the press release. Add these games to the list of 64-bit entertainments, which now include Far Cry, The Chronicles of Riddick, and (in a rather muted release) Unreal Tournament 2004.
Of course, we’ve also seen the release of dual-core and 64-bit video drivers from ATI and NVIDIA. The CPUs to benefit most from all of these updates may be Intel's 64-bit Pentiums, because they are currently a little bit lackluster in gaming performance. The Netburst microarchitecture does relatively better with code generated by newer compilers, struggles with x87 floating-point math (which is exchanged for SSE in 64-bit Windows binaries), and can take advantage of multithreading with even a single core thanks to Hyper-Threading. Interesting times, these are.
