After many years and my memory dulled I bit the bullet and went from 2000 to XPMore or less went O.K. and everything is workingBut FS2004 never finishes loading and PSP7 etcare as slow as a wet weekHelpI also see a program ??? Rundll saying it cant find NvQtwkHelpAny ideas ??Thanks in advance.Tas

Did you do a fresh install or an upgrade install?I always do a fresh install for a new OS. I dont trust the upgrade path.However, you can always re-run the XP CD and hit the "Repair Installation" option. This may or may not fix the problem.

NvQtwk is a nVidia Graphics Library Module. Re-install the lastest version of DX and download and install re-install the latest graphics driver for your card (of course now for WinXP. not 2K).Good luck,Pat

O.K.It is really strange as PSP7 rotated a 20 mb image in about a minuteacross both monitorsRhino2 loaded in a 120 MB file I have and only took a couple ofminutes to do the pretty basic render .Flight sim seems to go fine loading scenery/terrainbut at 68%/adjusting scenery objects it good as stops.But it does get there and is very slow and the mouse is almost stopped untill it is in one of the drop down windows where it is fine.Never quite seen anything like it.Tas

New OS, new chipset and mobo drivers, new sound drivers, new graphic card drivers, new install of latest version of DX9. Even if they are the same, reinstall them.If you've done all these things, then a good defrag is on the cards, as the hard drives will definitely be fragmented by an O/S installation. Allcott

Just a second, you're trying to run FS9 with a graphic board from 1999? I guess we found your problem.:-hmmm Pat

Well they worked worked O.K. in Win2000And they are working O.K. now as FS9 has finally decided to go to the default drivers.A bit slow but I am not going to buy a newsystem now as one would have to be madwith some of the price cutting that will begoing on soon.Any how I am a developer not a flyer.Tas
