Drops of FPS on high resolution

[Heavy_Volt]

Spec.
CPU Intel Core i5-4670K 3.4 GHz (boosted to 4.2)
RAM 8 GB
GPU NVIDIA GeForce GTX1080
Windows 10 64 bit

Since Update 24.3.0 my fps went down on high resolution and sometimes it's even lagging for ~1 sec. Problem occurs in all game areas, but it's most noticeable in high speed move (also in GPU drivers panel at right upper corner). Also recording eats over 40fps (since it's high resolution recording) and ~20% CPU (it never goes over 85%).

I know that minimum requirements for game has jumped up but everything beside CPU is not older than 2 years. Before update I was playing at 3620 x 2036 resolution on 144 fps and high graphics quality, so i instantly noticed that hiccup and didn't seen it in other games (even Monster Hunter World working at 60 fps ,witch is max for this game, is smooth).

So my questios are:
Is it natural for game now to do something like this ?
If it's not than what should i do to fix it (or at least get rid of that ~1sec. hiccups, I cant hit eidolon with this X( )
