What’s happening - or rather not happening - is that your textures aren’t loading.
You will always get the pink textures until they are finished loading – this is not a bug!
Dunno. Stuff on the screen seems to render in segments. Ground renders first, foliage with a slight delay, animals etc. last. I sometimes see that flash of pink outlines when a creature spawns, but not on the scale like in your screenshots.
Considering your hardware it shouldn’t be performance-related, even though I suspect CE can’t really benefit from the shiny features of RTX graphics cards.
This happens to me as well. I’ve noticed it for a while. When I started playing Age of Sorcery, it was there, so not something new to AoW patch. I just chalked it up to slow rendering and some new optimizations that were done somewhere along the line.
The pink is distracting, but honestly not a lot more distracting than slow rendering objects just appearing right in front of you. UE4 games are all crap at rendering, when you have larger builds.
