No warnings in log (if we're talking about those texts that show on the top left corner when the game becomes bugged). I haven't tried disabling GPU skinning, I don't remember ever tweaking with it. I've switched to Vulkan rendering ever since I downloaded A27 a while back, my GPU worked fine with it (I'm using a mac catalina). I really wish I was able to play A28, Delenda Est seems to be back, I think it's a great mod.

Do note that it reduces AO quality since the pieces take some space there

I'd really love to make them work like the Einherjar character from AOM.  

Yep. I think the Parthenon could use that treatment too.   And Greek docks.
