I'm not sure what is going on, but when I try and rotate in room view, it doesn't work about 80% of the time or lags WAY behind the moving of the mouse cursor. Shift+Left+Click drag, nothing, repeatedly. Then uncontrolled rotate to some arbitrary position.
Could this be because I have a kitchen that is to complex? 38 cabinets, 3 110" walls connected together in a U shape, and 2 42" half walls for islands.
Yes, I have the most up to date video drivers per my video driver board manufacturer (not Windows).
