Microsoft uses 3DMark to show DirectX 12 benefits
“3DMark  on Direct3D 11 uses multi-threading extensively, however due to a combination of runtime and driver overhead, there is still significant idle time on each core. After porting the benchmark to use Direct3D 12, we see two major improvements – a 50% improvement in CPU utilization, and better distribution of work among threads.”
With DirectX 12 game developers will be able to create richer scenes with more objects by better utilizing modern GPU hardware. DirectX 12 also introduces a set of new rendering features that will dramatically improve the efficiency of algorithms such as order-independent transparency, collision detection, and geometry culling.
I’m excited to announce that we are creating a new 3DMark benchmark that will demonstrate and test the full capabilities of DirectX 12.
