VRaySun Nitrous shadows

[Shimakaze]

I've been experiencing some difficulty on large scale scenes with VRaySun and realtime shadow display.
When setting a daylight system to mr Sun the shadows are perfectly crisp, but when setting it to VRaySun they become very low res and blurry with stepping and artifacting.
Is there any way to fix this, as I now find myself switching back and forth between the two between working and rendering.

Can you post a scene for this? In general we have very little control over what happens in the viewports. Still, it might be possible to make things better.

Ok, thanks - will see what can be done about it.
