Getting crashes

Before I begin, I know we are talking about a Beta and yes, I know it's a beta for a reason. 

On the good, it's like a new game.  When I played my first large scenario, I was getting slowdown all over the place...

Now it's like a new game!

But on the downside, I am gettings some freezes and crashes...I have an ATI raedon x700 for my card.

Any thoughts...or just wait for an update?  Version is 1.09[b].038
