I've been working with tech support this morning. Started a new project in X7 this week and have been experiencing delays when in 3d view waaay beyond what I'm accustomed to in X6. Edits that force a rebuild floors/walls take 5-10 seconds to appear on screen, where in X6 they were nearly instantaneous. I'm running a very high-end system (specs below), so this is a surprise. No clues from tech support so far, but if speed is your thing, it might be wise to avoid early-adopting X7 for now.
