"After first being introduced on Windows years ago, and then
FreeBSD and ReactOS support added last year, this week finally marked
the release of TitaniumGL for Linux. TitaniumGL is self-described as a
"freeware driver architecture" and carries a goal to support OpenGL on
graphics cards with broken, bad, or missing OpenGL hardware drivers.
Here are some benchmarks of TitaniumGL compared to NVIDIA's binary GPU
driver and the Mesa/Gallium3D LLVMpipe software rasterizer."
