I find that it takes multiple attempts in order to speak with NPCs, pick up items, and use items in my inventory such as EXP cards or equipping new gear. At times quests seem to fail to accept or turn in entirely despite having gone through the menu and interacted with the NPC, etc.
So far this does not extend to combat, but it makes it difficult to enjoy the core systems of the game like questing and loot acquisition. I also want to emphasize how inconvenient the issue with EXP cards is, since it lags for each one, if I’ve accumulated lets say 13, it can take a great number of clicks and attempts to use them all.
