VDrift is not based off the ioquake3 engine like the previous tests and is technologically more advanced than the three previous games with its use of GLSL, etc. VDrift also utilizes the Bullet Physics Engine and has other features to further tax the CPU. Even at 800 x 600, the VDrift frame-rate was below 30 FPS when taking full advantage of this Core i7 processor. At 1920 x 1080, the Core i7 970 with the current LLVMpipe driver provided just 11 frames per second.
Warsow uses the Qfusion engine and it ended up being even more demanding on LLVMpipe and the Gulftown CPU than VDrift. However, the performance continued to scale with the number of cores up through six, but Hyper Threading again had little impact on the performance.
