The situation is as follows
Calamity
+
Fargo mutan and souls mod + calamity add-on mod

Work well.
If I enable Fancy lighting mod, everything still works fine.
But if I add Terraria Overhaul mod. That at especially intense attacks of mobs (destroyer for example, on maximum difficulty calamity+fargo.), causes terrible lags and performance drops from 60 to 5 fps.

If you turn off either of the two (fancy lighting or terraria overhaul.), then everything becomes normal.

I do not have a weak system and even more so for terraria
rtx3060 12gb
ryzen 5 5600x
32gb ram

So it's definitely not a problem with my computer.


The situation is aggravated if you add mods like Avalon or Secrets Of The Shadows.

Periodically, all sound in the game except music even disappears and it is not fixed until you re-enter the game
