Hello, i have exactly the same problem. my laptop works with Intel core i5 M480 2.67GHz and AMD Radeon HD 6530M.
I have to set on low geometry, rest can be high, to start a map. with middle and high geometry it doesnt even start and crash immidiatly.
when everything is low, i can scroll into the map and it looks fine but then changing the view at some houses of a town let it crash again. at a wider look i can scroll over towns. but scrolling into them fails.
one more problem: at low resolution my window for my resolution options disappears, so that i cant change it again to higher / other ones.
