If you can REALLY see any difference on a 19" LCD I'll be amazed
You might be right but I reckon it looks much nicer on HD content, just more fluid and less tearing etc. On MPEG2 SD you might not notice.
Hmm.
Esp on HD content I cannot imaging where the difference in PQ should come from. If you have 1080p content displayed on a native 1080p display there is no scaling and no deinterlacing involved. If colorspace mapping works correct what else will have any influence on PQ?
I noticed that on Vista with EVR CPU load seems to be a bit lower than on XP with VMR but where is the point if CPU load on playback on all content never raises above 40% at all on XP.
I just ran the Vista setup for over a week now and currently I'm restoring the XPSP3 image. As I said no difference in PQ which should be noticably on a big display. What is also ugly that I have occasional hiccups on playback. This does not happen very often (one or two times an hour) but I do not get this on XP and so I'm back to it. If Vista SP2 is out (scheduled for April AFAIK) I will give it another try.
