Shadow visual errors

[thetestgame]

I recently started experimenting with the render pipeline and noticed shadows do not seem to render correctly. They always have this weird look to them and are not just flat.

In some cases it is even fuzzy and moving

My machine has a 1080 gtx and a 3.40GHz i7. I am also using the latest build of Panda3D

Hm, this is weird, did you change the settings of the PSSM plugin? Otherwsie I can imagine that your driver is performing additional filtering. You could try disabling settings like "PCF" in your driver settings ..
The moving is perfectly fine, the shadows samples are randomized to provide a higher sample rate, however, it should usually not be that visible - but I believe this is related to the filtering issue.

Id did however resetting everything to default does not seem to help. What "PCF" setting would you be referring to? I was unable to locate anything in my driver settings.

This is pretty weird, can you try disabling use_pcf in the Pssm settings and see if it gets better?
Also, if you lower filter_radius to something very small, what does happen then ?

[thetestgame]

Disabling use_pcf does seem to help. Almost all the problems go away when that is turned off.

It seems that you have some weird driver, which is trying to "optimize" the shadows, but makes it just much worse.
I think the Application is called Geforce Experience or something like that, maybe you have some weird settings there?

I don't see anything that could be doing it. An out of the box fresh install of the latest drivers still has the same issues
