My system is an AMD Thunderbird 1.2G with a PCChips M/B and the SiS 730 graphics chipset. Windows Update (I run W98SE) just offered an SiS driver update from 4.13.01.2000 to 4.13.01.2011 which I installed.
Benchmark results (from PerformanceTest3.4) showed a slight drop in 2D performance, but the ManyWorlds 3D test went from 51.8fps to 163.6fps - more than *triple* the speed.
Has anyone else seen increases like this? Seems almost too good to be true, not that I'm complaining...
