"When running the Lightsmark OpenGL lighting benchmark, which is more advanced than the ioquake3/Qfusion-based games, the Linux performance is horrific in comparison to Windows. The Windows 7 x64 Professional SP1 performance is far better than Linux and the open-source Mesa driver stack. If averaging the frame-rates from 800 x 600, 1024 x 768, 1280 x 1024, and 1920 x 1080, the Windows average is 55 FPS while the Linux frame-rate is just 15 FPS. The Windows performance is 3.66x faster than Ubuntu. Windows 7 started out at 82 FPS at 800 x 600 while Ubuntu 7 was just at 21 FPS. This performance difference is devastating."
LIGHTSMARK is a multiplatform OPENGL benchmark/demo in which real time global lightning and advanced shadows are rendered. This benchmark is designed to simulate typical workloads in real time rendering.
