Gallium3D LLVMpipe On Mesa 9.0
The Urban Terror frame-rates for the LLVMpipe Mesa 9.0 driver ranged from 24 FPS to 14 FPS.
The Qfusion-powered Warsow game was stuck running about 8 FPS the entire time when on the Mesa 9.0 LLVMpipe driver.
The individual data points for these LLVMpipe driver results can be found on OpenBenchmarking.org.
While LLVMpipe can handle a basic Linux desktop like Unity or the GNOME Shell if on a recent x86_64 CPU with multiple cores and modern instruction set extensions, even with the high-end Intel Core i7 3960X CPU it's still not viable at all for running old, visually-unimpressive OpenGL games. At least LLVMpipe also serves a purpose for Mesa/Gallium3D driver developers with having a slightly faster software-accelerated driver than Softpipe/swrast when it comes to debugging driver issues in being able to test problems on a hardware-independent driver.
