The pre-battle load time is about 1 second which isn't bad at all.  The game does do a camera shift at the beginning and the end of each round, then there's an after battle victory screen which takes a couple seconds, then a one to two second load to get back to the map.  It's noticeable but wasn't really annoying for the 15 minutes I played.  Graphics are decent enough, music seems good.  Unless I don't like the rest of the game I can live with it easily enough.
