i got several engineers, and all of them suffer from a slight to a extreme lag -that usually ends in either the game crashing or me having to shut it down manually- each time i learn a slot skill.
the different race’s slot skills are not affected and don’t cause lag, but stuff like kits cause a mayor lag, i have other professions as them and even when some may cause some slight lag, no other profession freezes the game on this.
mind you, the lag is random, it can go from 5 seconds to 2 minutes, after that the game stops responding
not sure if anyone else gets this, but i tried several races, profesions, areas, graphic settings, and it just burst on engineer slot skills for me
