I gave up playing it on the VAIO as it has a Geforce 9300M GS with shared VRam.
I then tried it in my main PC with an ATI FireGL v5100 and it crops up with shader issues stating that I need shader model 3.0 or higher, wheres the v5100 has version 4.0 :-\
I know this working in the 3D rendering industry :-\
