Futuremark, developer of some of the most popular benchmarking and stress testing utilities around, has recently release a slew of updates for various versions of their software. 3DMark06, 3DMark05 and PCMark05 have all been patched or updated, the updates free to those who already have a license for the existing software. The updates bring support for Windows Vista, but 3DMark05 does not have a small patch, instead requiring a full download.
The utilities are still designed around Windows XP, though having Vista support will make them some of the very few Vista-compatible benchmarking utilities. Other updates include support for Internet Explorer 7, additional CPU and graphics hardware support and many unnamed bug fixes. You can get the patches from Futuremark's site.
