I Just upgraded to Ableton Live 8 about 25 min ago. Before I got to loading one of my old Live 7 sessions I had been working on, I noticed how slow ableton was performing. CPU is 3x higher then normally in Live 7, and everything is running horribly slow; Tabbing between Session and Arrangement view, loading/deleting tracks, visual representation of audio levels render slowly on screen, etc. I even deleted the session down to two tracks to see how it performs and nothing changes. Poop!
