Vray Adaptive Image Sampler

Hellow mga Sir/Mam Ask ko lang regarding Anti-Aliasing issues, i know that has no exact values since they vary on the size and complexity of any Scene. Kaya lang baka meron kayong prang Thumb rule Values say for Min and Max subdivisions for the DMC sampler like for example for size A3 or A2 presentations. Nowaday kasi me mga Client's they prefer detailed results. Hope anyone could give me and Advise on this matter. Thanks a Lot
