Yes, in fact there's only two big differences between DX 10 and 11:
- The draw methods are in device context instead of device
- The resource map method
I see some papers from DICE (Battlefield Bad Company 2) that they ported their engine from DX 10 to DX 11 in only three hours. You are right, these are little differences, don't justify stop all work.
So, go on!!!!!!!!
I will keep everybody informed.
