But as far as your origional theroy about your gpu using the intel part of DX its it would be impossible as the way intel and nvidia render direct x are different.

ah well.. did say it a bit wrong. Just tried to say that the gtx680m is a full directx11 and though dx11 is backwards compatible with dx9, there are always dx9 parts/coding that dont work as optimised on dx11-only cards compared to cards that also can use dx9 (which is about 100% of the desktop cards and 90% of the laptop cards )). Though alot of it works perfectly fine, its just very small parts that arent fully 100% co-oping. Its like using a pen to draw a picture... sure its possible, but a pencil will always work better :P
