animation flickers

hi !

i`m rendering an technical animation. the szene has a high number of polygons (about 2 million). i tested some settings and the best i get are:

singel frame (object motion)

First bounce
-3/-1
Clr thresh 0,3
Nrm thresh 0,3
Dist. thresh 0,5
Hsph. subdivs 50
Interp. samples: 20

Secoundary bounces
Direct Computation
Subdivs 3
Depth 5

the main problem is, that GI flickers between the geometries :cry: and the rendertime is about 30min by a dual MP2000 (960x540) !

doese anyone have an idea :?:

please help…

re

don’t interpolate glossy reflections…set the subdivisions to something inbetween 10 and 20
