With OpenArena 0.8.5, on the high-end AMD FX-8350 CPU the frame-rate was just around 19 FPS at 1920 x 1080 with the LLVMpipe driver. Using LLVM 3.2 SVN over LLVM 3.1 on the "bdver2" processor had minimal change in performance. The GeForce 8400GS graphics card on Nouveau was at 23 FPS, albeit when using the Nouveau driver with the Gallium3D driver that is also not consuming the entire CPU resources.

With the more advanced OpenArena 0.8.8 release, LLVMpipe on this hardware was running at just 5 FPS. Building Mesa with LLVM 3.2 SVN hadn't changed the performance for the AMD hardware.

World of Padman was averaging 20 FPS on LLVMpipe for the octal-core x86_64 processor.
