Add a perf test for pure draw call overhead #955

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
We can use the D3D NULL drivers to benchmark pure draw overhead on the D3D 
back-ends. Will have to investigate the possiblity of doing so with the GL 
back-end.

Add a perf test for draw call overhead.

These perf tests use the D3D NULL renderers to measure pure CPU
time, with no GPU limitations. Also fix our D3D9 SwapChain code
to skip creating a SwapChain for NULLREF D3D9 devices, and the
vertex decl code to reinitialize the formats when finding a
mismatch with the previous value.

Disable vsync for perf tests and don't report the total time.
