I can confirm, Max Til 8 helps. Master diese now at 474 from 512. It's ok for a 2 minute rendering, but as Thanu said, for heavier scenes it is still a problem.
I'm glad you guys looked into it in a more specific way. Though it's a little frustrating to know i brought this topic up weeks ago.
Anyway, lets hope it can be fixed in the main SDK. Can you keep us up to date in this thread, bepe?
