WTF happened with loading screens? Is this performance patch or something? For what reason exactly changing sanctum rooms now takes literally 5-7 seconds loading time? Toilet-size rooms 5x5 meters exactly? I don't understand... It was almost instant before... Now my run literally takes x2 time with loading screens after EVERY room

Okay so it takes exactly 6 seconds to load to another sanctum room, do you even imagine how it prolongs the run? My friend reports the same. No way im playing the game in this sorry state. Performance patch xddd
