How do I fix Chromium-based browser lags

Is it through chroot?

Yes true but I changed to nomodesetting before I saw that post that day. But I guess I could try it again through the temporary Grub settings

Edit: So I actually don’t know where to ad this nomodesetting (so I asked in the other post on how to do this) but regardless if it failed without changing it in the grub settings, I am sure it will fail if I did this through grub, so in other words I need to have modesettings.
