@deprecated_ii@eee Most likely the problem is some shitty coding where game actually does some check "map is opened" perpetually, when its opened. Or its some shitty engine which cant handle realtime resource loading, and map was deemed non-essential, so its slow. Some unity engine devs advice to use 8*8 textures, because engine cant load anything.
I am more annoyed when typing prompts kill framerate to single digits. Its clearly some bug, but why bother fixing it.
