vLite can help, but in the end there is only so much that can be done and Vista will never be as fast as XP. I wanted to watch a video on Hulu.com and it skipped and stuttered on 480p video to no end on Vista (w/ DWM/Aero Glass disabled and using Windows Standard theme). So I ditched it again for the n'th time and put XP back on. XP plays as smooth as butter even on 720p... and I don't even use nLite at all. I will give SP2 a try when it is finished but it'll probably still be disappointing.
Note that this would have less to do with Vista and more to do with the video driver, unless you were using 1GB or less of RAM (in which case the behavior you state would be something I would expect with 1GB or less of RAM - only Home Basic has a minimum requirement of 512MB of RAM, and all other versions state 1GB, and running "minimum" requirments gets you "minimum" performance).
People tend to complain about Vista being "slow" on 512MB or 1GB RAM machines compared to XP, and that is true - but one has to remember that the XP codebase is much closer to the original NT codebase than Vista is, has fewer features (yes, these do use resources), and the code is 8 - 9 years old in most cases - it is leaner, and runs faster (it's also less secure and has fewer features, but that's the trade-off). That versus Vista's codebase, which is circa 2005/2006 code (and it could be argued Vista SP1 is the "real" Vista, circa 2007/2008). Regardless of how you feel about it, running Vista on an older CPU with less than 2GB of RAM *will* likely end in frustration.
