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!

Is there a way to get shadow map shadows to stop flickering even when

This is what I have tried to no avail.
On the spot light (cone angle less than 90):
Resolution up ( and down).
Softness up and down.
Samples up.
None of these make any diference to the flickering.
On the render panel:
I've played around with the antialiasing and jitter.
On the shadows page I've clicked off rebuild.
If you view your scene from the light is there an extremely large
depth to the objects? In other words, are the closest object to the
light and the farthest object from the light extremely far apart? This
can lead to ZDepth (used for shadowmaps) presision issues in some
renderers.
This is often the case if you have a huge ground plane.
You may be able to exclude some objects, to help, or make smaller
versions that catch shadows.
