Hi Ulfbritt, glad you like it!
I'm currently working on some new features to make it a little more usable. Hopefully I'll have a release within the next few months.
Were you able to get it working with the GPU?
Be sure to consult all of the documentation on fractorium.com
If you have a certain question, just try typing some of the terms into the main search box below the download buttons and you ought to be able to find what you need.
If you still can't find what you need, you can always email me. My email is on the contact page.
