i had problems getting alias running, with oxygen gmx2000 on win2k, it was very slow to refresh and rotate simple geometry. At best guess there is still alot of teething problems with win2k, especially if it is a new line of video diplayer. your cards drivers havent been qualified by microsoft on win2k yet, as was the one i have. i had to return to NT and my problems were solved.
