i was fighting infernum dog when my game dropped to fucking 10fps when he did any attack involving lasers, didnt happen at all before. the only difference was the new calamity update and i also disabled core isolation. once i re-enabled it it ran perfectly fine, even when he did the massive laser wall attack.
not multiplayer, windows 11, 32gb ram, rx 7800xt and a r5 7600. let me know if anyone needs a log file
