Graphics chip makers have now had plenty of time to get to grips with the new driver model and the performance gap has been slowly closing. Today, there's precious little in it.
Our verdict
It's tricky to capture with benchmarks the sort of subjective glitches and slow downs that anyone who has used Vista as their main operating system for an extended period will be all too familiar with. Anecdotally, at least, Vista installations seem particularly prone to growing fat and wheezy.
Certainly, Windows Vista is packed with all sorts of subroutines and hidden processes - such as file indexing, application caching - that are ostensibly designed to improve performance. But the same measures can also induce an enormous amount of what seems to be entirely unnecessary disk activity. It's not unusual to find an idle Windows Vista box making a noise that sounds uncannily like the hard drive chewing a brick.
Nevertheless, there are one or two areas of real interest from our objective benchmarks. Firstly, SP1 has solved Vista's previously feeble zip file handling. It's now on a par with Windows XP in that regard. SP1 also remedies a small but worrisome shortfall in memory bandwidth compared with XP.
However, a particularly popular gripe that SP1 does not address is Windows Vista's piggishly resource-hungry nature. If there's a single figure that sums up the perceived bloat it suffers from, look no further than Vista's memory usage at idle.
787MB is an absolutely ludicrous amount for a system to swallow from a fresh boot of a new installation. Windows XP squeezes itself into just one fifth the space.
In the end, SP1 is undoubtedly better than the original RTM build of Vista. Windows We're glad to see Microsoft at least attempt to address the criticisms that its latest operating system has attracted. But it's probably not enough to prevent Windows Vista from going down in history as marking the beginning of the end for the Windows project.
