Just did a small test:
Just 4 passes
GI/AA: 24
MSI: 10
You need to unlock the sampling pattern
Elemtents: Beauty, CGeometry_NormalsShading, CShading_SourceColor (Albedo?!), CShading_Shadows (VIS?!)
(Not 100% sure if these are the best passes for the AOVs)
Rendertime: 1:40 min per image
Filtering Time: 43Sec
Edit: tried to process a 4960x3508 Image, but there is not enough ram on my gtx 970 und the CPU-Mode does not work for me...
