I just got a brand new Vista computer with plenty of RAM, processor speed and the DirectX 10 -- I have enjoyed playing Luxor and Luxor 2 on this machine -- but the most fun looking of all (Luxor 3) doesn't seem to work?

I have only played a trial version but it is PAINFULLY slow -- the graphics are halting and it takes the coins about 10 seconds to fall from the top level... the particle effects are so slow you can count the dots. I saw a YouTube of the game and it's just as fast as all the other Luxor series games.

PLEASE -- has anyone else had this? I've run in compatibility mode, run as Administrator, -even did a restore of my OS -- nothing has worked and the game is so slow it makes me too frustrated to play.

HELP
