LLVMpipe On Mesa 8.1 Performance

The old shader-less OpenArena 0.8.5 release can go above 60 FPS when at a resolution of just 640 x 480 for the Intel Core i7 3770K "Ivy Bridge" processor, but anything above that its OpenGL frame-rate quickly drops. At 1920 x 1080, the LLVMpipe frame-rate for this old ioquake3 game is just 25 FPS. There's no change in performance for this multi-core Intel processor with LLVMpipe between Mesa 8.0 and the latest 8.1-devel code from 6 August 2012.

With the latest OpenArena release, version 0.8.8, even at 640 x 480 the frame-rate is below 30 FPS. There's no performance improvement attributed to Mesa 8.1 / LLVM 3.1.

The World of Padman performance is also sluggish and unchanged with Mesa 8.1-devel.
