According to HardMac.com, Apple is massively underclocking the ATI Radeon X1600 graphics processor fitted in its Intel-powered MacBook Pro laptop PCs, the aim presumably being to cut down cooling fan activity - to reduce noise and extend battery life (by about half an hour, says HardMac).
However - and you just knew we were going to say this, didn't you? - the clever sods who found this out also realised that it's possible, when running Windows XP (see our recent review of the Apple Boot Camp utility that enables OS X/XP dual-booting), to download from ATI tools and drivers that let the GPU run at full speed, greatly increasing the framerates that can be achieved when playing games and benchmarking.
