I have found moving things is slower, also. May want to try tweaking your interactive render settings some higher opengl stuff can really slow things down. I have also been getting memory allocation errors. Need to look into that, could have more ram.Got a gig.A tree seems to do this.I am wondering about the parametric mapping. If I restart all is fine. Makes me wonder about leaks. I confess I like the new shader tree much better. Fits better on screen w/ long textures.I like vertex room much more, but I use hex, however if I go in there it is much easier.The interface isn't that much different just cleaner and more consistent. Try changing the colors to your prefs you might find it more comfortable.It can often take an adjustment period when your accustom to certain things.

No need to think outside the box....
