Sometimes when use shotgun there is an fps drop, not always sometimes it can be smooth but often there is significant fps drop.

yes same prob here too , when i use handgun and shotgun white light appear and fps drop , if i do this many time is totally stable no fps drop .

Have you tried to turned off networking/WLAN?

[Lemoncak3]

Nope not working, have turned off networking and still have same issue. I think it's not related to networking, but i do try it in multiplayer and same fps drop happen. So maybe something else..

Pretty similar to the FPS drop issue in Final Fantasy Type-0 (#13464) where it goes down to 23-24 fps when performing a one-hit KO.

I know that there is an issue on Kingdom Hearts Birth By Sleep when using the "Vanish" command using Vulkan.
It will lag the game.
I only saw that being on reported on Android though.

I am using OpenGL though not Vulkan, i rarely use vulkan on my device.

May be the cache kicked in that's why it's no longer lags with repeated usage.

Could you try to disable texture upscaling and see if it help?

[Lemoncak3]

Texture upscale level? I have turned it off but the lag still there..

Game is probably doing something like raycasting. In the case of the shotgun, multiple ones maybe.

Can confirm though it only happens when caching. After that, speed doesn't get affected.

maybe the problem fixed . plz try and inform

This is likely the same as what happens on the first hit in Tekken 6, which also stalls - the lighting environment changes drastically so the game compiles a bunch new vertex shaders to handle the new lighting setup, this causes a stall.

This is an area that I plan to improve, both by using lighting "ubershaders" on modern hardware, and parallel shader compile on Vulkan.
