Not too old, and one of the better cards, if I remember correctly.

@ the developers: Maybe, you should start the game in mode without shaders? Not sure weether this is the reason, that it doesn't run on firoball's system.

On the wired camera move, if you make the stairs as a tilted surface (not sure, wether this are the right words), you got rid of this effect, and when the guy is walking down the stairs, he want change into fall animation. To make stairs in that way is common, Max Payne among others (maybe Rayman 3D too, to mention a cartoony game) had this sort of stairs.
