When running Nexuiz, the performance at 1024 x 768 on both Ubuntu 10.04 and Windows 7 was very close at just over 60 frames per second, but when upping the resolution to 1600 x 900 to put more load on the GPU, the ThinkPad W510 ended up doing better on Windows 7 Professional. While the proprietary NVIDIA drivers were similar on the two platforms, Windows 7 was faster by 9% over Ubuntu Linux.
The ioquake3-based OpenArena game is the least GPU-demanding test we ran in this gaming round up. When OpenArena was running at 1024 x 768, Ubuntu 10.04 LTS was faster by about 3%, but both Windows and Ubuntu Linux were running at nearly 300 frames per second. When the resolution was increased to 1600 x 900 the frame-rate was still above 200 FPS, but this time Windows 7 Professional wound up being 10% faster than the open-source operating system.
With Lightsmark, a popular OpenGL lighting benchmark, Windows 7 Professional was much faster than Ubuntu 10.04 LTS at both resolutions. At 1024 x 768, Windows 7 was faster by 28% and at 1600 x 900 it was faster by 41%.
