Sure thing, glad we could make some improvements, and the form in which you presented the problems made it very easy for me to investigate (simple scene with download, clear demonstration of serious problems). Thanks to everyone who helped in this thread.
This is just a step in the right direction. Once you guys get 4.11 we’d like to know what the new primary limiting factors are for Archviz. We won’t necessarily be able to solve them all due to time constraints, but at least we’ll know what’s most important.
