I made a small demo based on the crowed of the 3dgs folder. I used the original code from Crowed.c, shadows.c, vp_pssm.fx and vp_depth.fx.
Here is the File:

PSSM Test Demo

On my system (and other systems) with nvidia graphic card:
source code: WORKING
published exe: WORKING

On my second system (and other systems) with radeon graphic card:
source code: WORKING
published exe: NOT WORKING - the engine crashes without error message.

I hope we will find the Problem and can fix it...
