Im guessing either we need DX11 hardware or DX11 games to really see something.
From Wiki:
"The Direct3D 11 runtime will be able to run on Direct3D 9 and 10.x-class hardware and drivers, using the D3D10_FEATURE_LEVEL1 functionality first introduced in Direct3D 10.1 runtime. This will allow developers to unify the rendering pipeline and make use of API improvements such as better resource management and multithreading even on entry-level cards, though advanced features such as new shader models and rendering stages will only be exposed on up-level hardware."
But when we see the touted backwards compatible DX11 performance benefits and features (multithreading,etc). Will those require new drivers, or do games need to be patched to take advantage of them?
