LLVMpipe Still Is Slow At Running OpenGL On The CPU

Unfortunately, even with the updated Mesa/Gallium3D/LLVMpipe code, OpenArena still is barely playable even at 800 x 600 with this software driver even with eight logical CPU cores. At 800 x 600 on the Core i7 920 setup the frame-rate averaged out to just 28 FPS. This is actually a drop compared to using the older software stack where as in our last LLVMpipe article on the same hardware it was at 35 FPS. Meanwhile, even the GeForce 8400GS using the Nouveau driver that is not nearly as well optimized as the proprietary NVIDIA driver (as yesterday's numbers show), was able to put out 71 FPS. At 2560 x 1600, the LLVMpipe driver was churning out only four frames per second.

With World of Padman it is pretty much the same story using the LLVMpipe driver: even at 800 x 600 with a high-end Intel Core i7 920 CPU the ioquake3 game still is only on the brink of being playable.
