Now I will admit that BG3 doesn't quite match ESO in terms of long looonnnngg I mean really looonnng and annoying loading screens, but it's up there.
If they are going to be this long, please add more shots. I rotate through all of them, then half again more every time.
Suggestions:
More pictures/more variety
Use screenshots from our game history (something like Fallout 76 does)
Very slightly lengthen the time per picture
