well theres really nothing there except:
and this lag didnt happen on non arch distros?
hmm, it could be related to nvidia… try adding the ibt parameter:
open this file:
sudo nano /etc/default/grub
and inside this line: GRUB_CMDLINE_LINUX_DEFAULT inside the quotes add this parameter:
ibt=off
dont remove anything, just add it to existing parameters, save the file with ctrl+x, update grub:
sudo update-grub
reboot and see if it helped
