Mostly I just use min -1 and max 2. and box filtering 1 or sometimes I
use triangle 2 for a softer effect.
I output a string of 852 x 480 bmps to my clients and then they mpeg it
somehow and wack it up on big plasma screens. They never complain. When
they want stills for print I just render a frame out huge (3000+)but
leave the antialiasing the same.
If it's for telly I do HD res. If it's to be comped with live action I
ask what anti aliasing they want.

Samples 20 is a bit low. I generally put 64 as soon as I set up the
shadow map.
What do you mean with "standard antialiasing"?

OK. I dragged the spotlight in closer to the scene elements and it seems
to have stopped all the flickering! It wasn't that far away, but now it
is almost close enough to make my character sweaty. I also scaled down
my ground plane a tad.
Just using 1024 res and sample 20. And bog standard antialiasing.
So very BIG THANKS to all who replied!
