Just checked AF2.0 on my Windows machine and the layout has some heavy slowdowns I don't see on my Mac. I suspect the culprit here is the nested surface used for logo shadows, I solved it in the past with some tricks so I'm positive I can solve it soon.
- UPDATE - solved the issue with the slowdowns, I'll re-check it on the Mac and then post the update to 2.1
In the meantime I wrote my own blur shader, but I discovered that a single pass 2D shader, even if it only requires one surface to apply, is overall slower than a dual pass 1D shader, which requires two nested surfaces to work.
