It seems ok however I experienced my first crash ever with cubase after installing and working on a previously created project, seemed ok the rest of the session but I did have a couple instances where it completely froze my computer for about 30 seconds and the session was not huge nor is my computer under powered. The point is I have never seen that before.
I also still have cpu spikes from 60% immediately to clipping thru out out the session even though I froze any tracks using cpu. This only showed up when I moved to 7. Guess I have some digging still to do.
