Hi Apophis,

First for you performance problem, check this in the options settings :



- Unchecking the 'add detail to inflections' will boost MoI.

I don't think MoI is multithreaded for the moment, so you should have mostly the same speed as in the video (quad 3.0 here).

For the fillet problem, it's a question of sequence to respect :



The edge you're pointing should be filleted before the side surface.
(You can still correct it, I can create an other quick video this evening)

For the offline video, I have to check how I can do that using the screencast service.
