Comparison
Method : BUCKET PT+HD
by tests carried out, the result was as follows:
casuistry
a) for negative values of AA greater noise
for positive values of AA minor noise (uniform effect in relation to Ath.)
b) AA>=Ast. 0,15 <Ath.> 0,02
c) with values of 3 <AA> 2 and Ast.= 2 required minimum 5 Passes
with values of AA= 4 and Ast.= 2 required minimum 3/4 Passes
d) with values of AA>= 4 and Ast.>= 3 required minimum 1 Passes (Passes> 1 the higher the rendering time)
List, I report the comparison of some selected values on a base Size 1920x1080 :
A = AA 5 Ast. 3 Ath. 0,04 | Time: 1:19:22 | Passes: 1
B = AA 6 Ast. 3 Ath. 0,05 | Time: 1:34:16 | Passes: 1
C = AA 4 Ast. 4 Ath. 0,02 | Time: 1:58:57 | Passes: 1
D = AA 4 Ast. 2 Ath. 0,09 | Time: 1:37:03 | Passes: 3
E = AA 9 Ast. 3 Ath. 0,08 | Time: 2:01:09 | Passes: 1
Of course, the times are always in function of the hardware in use and the size of the rendering and setting GI secondary
