Below are the comparisons between DX10 & 11 and DX11 Demo.
This is a comparison between DX10/DX11 gameplay set in the Jungle and
DX11 Demo for comparison. There is an improvement in DX11 architecture
over DX10 in rendering and a reduction in hardware intensive tasks due to MSAA and texture
mapping (one pass sampling) producing a balance between cpu and gpu load.
Althought there are no frame rates included, it is showing the difference smooth
gameplay in a realalistic situation as compared to the demo version.
