In the spider cave it took the 30 spiders about 10 minutes to finish each one of their turns but I guess the combat is too slow.... Hi welcome to the BG3 forums have you even played it?
Curious point, none of those spiders were using reactions beyond opportunity attacks, this change will not affect the time it takes for the spiders turns.
Also you are right, they need to improve the lag between enemy turns (optimization), and the spider phasing animation it’s a little bit too slow.
