RE: flicker amd drop out

it's not the right angles, it's the fine detail. Thin lines are the worst. Unfortunately there's often no real cure other than to switch off the adaptive sampling.

I'm working on architectural shots right now, probably the worst anyone's likely to get for aliasing. I'll keep you posted and if you want to nudge me in a couple of weeks then that's fine, but for this kind of work I'm pretty sure:-

 

min/max: 1,2 or 2,2. at 1,2 set threshold to around 0.1, less for fine but contrasty detail is probably not going to get you much and at 2,2 the threshold is irelevant. And Chris is right, turninng on dithering will amke a big difference.

II had my aliasing settings at 0 and 2 with the default threshold and .the Mitchell filter.  I did a quick test of Chris Marshall's suggested settings (thanks Chris) and there was a definite improvement but still noticible tearing with that chaser light effect on many edges. Do I try a higher threshold or min max setting?

 

Thanx in advance,

You need to play with this, but a lower threshold, maybe .025, and maybe a min max of +1,+3.
Try changing the min max first.
Like Kim said, architecture is always a pain!
