"Released a little over a week ago from id Software was the Quake 4 v1.2.0 patch. The patch addressed the monitor issue that had initiated an immediate recall of the v1.1 patch at the end of March. One of the issues, however, that has been lacking from the Linux version of Quake 4 has been SMP capabilities. Quake 4 within Microsoft Windows has supported SMP and Hyper-Threading Technology since the v1.0.5 point release, while the Linux feature was non-existent. This feature allows Quake 4 to take advantage of Hyper-Threading Technology in Intel Pentium 4/D processors and other multi-core systems. Systems with multiple cores should notice significant performance gains when running Quake 4, permitting no other hardware bottlenecks. According to id Software, systems with a single physical core but those capable of benefiting from Hyper-Threading Technology should experience a 25% performance boost. Systems with two or more physical cores should see up to an 87% improvement. The true benefits may vary greatly depending upon the CPU and GPU limitations as well as other factors..."
