Talk about eerie. I request the name of the model ... I have it. :) I haven't had any problems trying to use it, or the bump map with it, but I'm a PC user. Definitely not your processor, that's more than sufficient to handle it. RAM might actually be part of the problem, then. Not sure with a Mac. Something else. The model does say PC only. Did you do anything special to convert it, or are you trying to use it straight out of the box? If it's a conversion problem, there are a LOT of Mac users in here that might be able to help out now that we know what you're running.
