Quake 4 patch promises performance for SMP systems

Activision has released a beta 1.0.5 patch for Quake 4 that reportedly increases performance with dual-processor, dual-core, and even Hyper-Threading systems by between 25% and 87%. There's no word on how the patch distributes workloads between multiple physical or logical processors, but it's encouraging to see developers working to take advantage of idle cores. This won't be the first time Quake has run on multiple cores, though. John Carmack tinkered with SMP for Quake III Arena, although real-world performance in games never quite measured up to expectations. If you're curious to see whether the latest version of Quake makes better use of multi-core systems, you can grab the beta patch over at FileShack.
