The image shows the problem. As you can see at the left edge of each screenshot, shadows in Standalone are better, so maybe they are the cause of better looking Standalone version…
But where can I set to make PIE appear the same as in Standalone? Graphics quality settings are already set to Epic.
It looks like post process AO difference. Is PIE window resolution the same as standalone? This kind of difference may occur if they are different.
Yes, resolution is the same. The most visible hint for me is the shadow near the left edge (on top of the white box) - in Standalone is crisp, but in PIE it’s almost invisible, blurred…
OK, I got it - scalability settings was set to Epic, but ‘Monitor Editor Performance’ was resetting this in PIE. Unchecking this option helped.
