I can t update my driver

You have some options now. 1) Install another Linux system as @Aravisian said 2) install previous Zorin OS (15.3) 3) Use your Zorin 16 as it is, but no 3D gaming.

You need to install browser extension and install Gnome extension app from software store

but why?

It's how it works with Gnome extensions.

like what it does?

It monitoring the heat and fan of your video card.

while playing?

It will sit in the panel next to the clock monitoring all the time and yes also while you're gaming.

On browser only right

you need Firefox addon called Gnome Extensions and after that you need to install Gnome Extensions from Zorin Software store. Afterwards it may require that you log out.

I m gonna do it tomorrow because i m gonna sleep now

And wdym with log out?

Log out of your Desktop, so the changes can take effect.

So u mean reboot

And will 384 work?

(Check the reply)

A reboot can also do. But a logout will take you to the screen where you login to your user.

So its like reboot

No. It's where you can change to a different user if needed.

And will 384 traditional package work?

Its like 390
