I did some more phone calls and it turned out that I have to wait a bit before I can run the WDM driver. I did install the vxd version of it and it runs very nice at any resolution. When you scale smaller than 240 there are similar aliasing effects but not as pronounced as with the FreeBSD driver. Unlike FreeBSD where the Ximage performance is acceptable you only get smooth picture quality if you use the overlay surface. Bottomline, today the FreeBSD driver looks better. Next round when I get the WDM driver to work, which is probably in 4 weeks.
