Captn,
I hadn't considered a fully double buffered approach like you suggest, I had it in my head that xv will give me a screen and I draw to it.
It seems obvious in retrospect and could yeald additional performance benefits (especially for the lower cpu modes).
When I next dip my head into the engine I'll take a look around and see if theres anything I can do.
Thanks for the tip, it very likely may be useful.


Why haven't you got a tablet?
