Running slow

I've updated to v.6 It seems to run really slow. For example, I have to layers I make a simple change, like select a new formula. the status bar at the bottom will run for up to a minute while it calculates. I don't remember this happening on v. 5.

I had the same problem initially. You need to go to View > Preferences > Defaults. Where it says 'Anti-aliasing' uncheck the box marked 'Enabled'. This makes a huge difference to the speed! UF6 is actually much faster than UF5 once you do this.

I will just add that it is also possible to turn anti-aliasing on or off on a per image basis on the fly if a wholesale Off setting is not wanted. There's checkbox on the Fractal Properties > Image tab for this. From my experiments I believe the on/off setting is saved with each image.

I like the flexibility of this - you can temporarily disable the AA preview while you make adjustments to an image, for example, to speed up the re-drawing process. It can then be re-enabled just before committing to a long render to get a better idea of the final outcome. For simple, more "lightweight" images it can just be left on.

thank you Otto and Velvet for the informative and quick replies!
