The only issue I'm having with V2 is the peculiar movement of the aircraft shadows when panning around the aircraft when cloud shadows are enabled. This goes completely when cloud shadows are enabled, as seen here:
You have to watch the shadows at the shallow viewing angles angles seen above. Other than this, V2 is superb EDIT: Also forgot to mention, this does not occur in cockpit view even with cloud shadows enabled. Flying into the shadow of a cloud does not seem to have any effect on the cockpit shadows and the wings do not appear to be darkening in the shadows.
