A Phoronix reader that goes by the name dragoran has managed to achieve some success with the Quake 4 v1.2.1 SMP binary. Using a NVIDIA GeForce 7800GTX, 2048MB of DDR system memory, and AMD Opteron 170 (dual-core) overclocked to 2 x 2.7GHz he has managed to achieve an approximate 19.5% performance boost. The numbers he had reported to Phoronix was a 75.69 average FPS number with the single-threaded Quake 4, and 90.50 FPS with the quake4smp variant. Running on his system was Fedora Core 5 (x86_64) with the 2.6.16-1.2096_FC5 kernel. The demo used for benchmarking was playnettimedemo id_demo001. Even with the numbers reported, the 19.5% frame-rate improvement is no where comparable to id Software's stated 25% jump on Hyper-Threading systems and up to 87% on two physical CPU cores. We are still continuing our Quake 4 SMP investigation, and feel free to share any successes or failures with this game using our contact page.
