So I installed a trial of Crossover and used it to install the Windows version of DDO. Actually got it running (using a couple different tips in this forum). Unfortunately, it was all jittery. I tried lowering the graphics quality, but that didn't help. Different resolutions didn't help, either. Kind of bummed. Thought I had it. Looks really nice on my ultra windscreen monitor, too.

If anyone else gets in running smoothly, please post.
