I feel like I'm getting performance below what I've been getting on windows for the same games when I'm booting in Linux. Top of the head example is COD WWII, the gameplay and cutscenes stagger a lot but runs fine on windows with the same hardware. I've checked that my graphics card is being used by Linux but I just feel like I'm missing some settings that would optimise it.

I'm running Linux mint with a NVIDIA GTX1070. I know there's some issues with NVIDIA and Linux but would that be the full reason?

Question about moving from Ubuntu to Debian - Package updates and security updates...

On Ubuntu, I seem to get notifications almost every week about new package updates. (Through the apt UI)

On Debian, I don't see this.

I can run apt update and apt upgrade

On Ubuntu, I see this pull a bunch of package data from various package repo URLs.

On Debian, I only see this pulling package data from two or three repo URLs at debian.org

Mainly I am concerned about security updates and bug fixes. Do I need to manually add other repo sources to the apt config files? Or does debian update those repos regularly?

[interview question]

Assuming a user is a root, can this user create a file that couldn't be read or deleted by other roots? ....by the same user?
