Need help! Triggering a perk like Idiot savant or picking up cap boxes cause stuttering like 0.3 seconds.

[aegesrhrtgyhyhj]

My game gets stuck for about 0.3 seconds every time one of these animations appears on the ui (Includes perk animations like reaper's sprint).

I've found that eliminating some animation packs and related patches can greatly alleviate this situation (especially UAP). But when I asked other players, they didn't seem to have the same problem as me by installing the same mods.
So I feel confused. Can someone help me please?
Anyone else in the same situation? qwq
