What you think about adding an SSAO Compositor to Iris2? Of couse you could turn it off.
SSAO adds more realistic Shadow-Lithhnting to a scene. The famous german Game Crysis uses the the technique

pros:
Compared to other ambient occlusion solutions, SSAO has following advantages:
* Independent from scene complexity.
* No data pre-processing needed, no loading time and no memory allocations in system memory.
* Works with dynamic scenes.
* Works in the same consistent way for every pixel on the screen.
* No CPU usage – it is executed completely on the GPU.
* May be easily integrated into any modern graphics pipeline.
cons:
* Rather local and in many cases view-dependent, as it is dependent on adjacent texel depths which may be generated by any geometry whatsoever.
* Hard to correctly smooth/blur out the noise without interfering with depth discontinuities, such as object edges (the occlusion should not "bleed" onto objects).
