Well, my system pretty much hates beta 2. Almost immediately, the interface become so sluggish as to be completely unusable. Trying to set up the preferences for my audio interface was basically impossible.
I did manage to tell that AV sync (for clips with both audio and video) is still way off though.
I saved a log from the crash that happened on quit, and will forward that.
NOTE: Everything I tried runs effortlessly in Avenue 3 on the same system.
Looking forward to Beta 3.
