+==============================
+    The interesting "what is a bottleneck" experiments are
+    (from back of 3D pipeline to front):
+    - Disable blend (= disable related dst reads)
+    - Binding 1x1 / NULL texture instead of real ones [1]
+    - Using simple pass-through pixel shader instead of real ones [2]
+    - Use kill / discard pixel shader instead of real ones
+    - Use 0x0 / 1x1 scissor rect
+    - Front+backface cull
+    - Disable draws
