I've read how complicated 3D acceleration is on a virtual system, so I just have a general information type question. Of course the game I want to play is not in the list of working games so I was wondering if anybody had an estimate of when 3D acceleration will be good enough to not be considered experimental? Is the delay due to the amount of work that needs to be done (time spent doing it) or information that still needs to be learned? I'm assuming the goal is to have 3D work on a virtual system just like it does on a physical system so individual games don't have to be debugged?

Thanks,

Larry

PS Technical answers would be wasted on me!
