Hi. using google translator here.
this problem appears when I try to run the game on windows 7. I managed to solve using an application to configure shaders called RESHADE. when I opened RESHADE, I added the pillars of eternity executable to the selection screen and chose the directx 10/11/12 option. I didn't check any more options. when confirming the selection, I closed the reshade. so the game worked normally. I can't explain well why this worked. maybe some expert could. maybe it works for you.
this is the link where i got it: https://reshade.me/.
"just for the record, my drivers were up to date and direx was up to date."
