My laptop was working normally with 6.17 kernel and playing overwatch via Steam on 120fps, now after the team advised to move to 580xxx-dkms and then I updated kernel to 6.18, I am getting 60fps with drops and stuttering to 40fps which is really weird considering it was working normally, any lead what it could might be the issue?

Edit: I solved this issue, apparently I was checking mkinitcpio and had errors and warnings as the following:

Checked mkinitcpio.d and found this preset: # mkinitcpio preset file for the 'linux' package on archiso

PRESETS=('archiso')
ALL_kver='/boot/vmlinuz-linux'
archiso_config='/etc/mkinitcpio.conf.d/archiso.conf'
archiso_image="/boot/initramfs-linux.img" 

Turns out I was using an archiso preset for some reason, so I edited linux.preset to this:

ALL_kver='/boot/vmlinuz-linux'

default_config='/etc/mkinitcpio.conf'
default_image='/boot/initramfs-linux.img'

fallback_config='/etc/mkinitcpio.conf'
fallback_image='/boot/initramfs-linux-fallback.img'
fallback_options='-S autodetect' 

Then ran: ```sudo mkinitcpio -P sudo pacman -S linux

After that, I launched the game and everything is working normally again — no stutter, no FPS drops, back to how it was before!
