Graphics Support - Slow and lagged performance

I recently flashed my Windows 11 with Chimera and noticed that the screen lags frequently when playing games which was not an issue in Windows 11. I'm thinking the graphic drivers for my NVIDIA RTX 3060 need an update in Chimera. I tried the following commands but it did not work.

sudo pacman -S nvidia (Cannot find root password anywhere to run the command).

What else can I try to update Chimera, Graphics drivers and Steam Client?

I have an MSI Trident 3 12th (i5 12400F) , RTX 3060 12 GB, 16 GB RAM.

Start with the reported MSI Trident 3 hardware, ChimeraOS installation, and the failed `sudo pacman -S nvidia` command. Investigate the graphics-driver, ChimeraOS-update, and Steam-client behavior described in the issue; done means identifying and documenting a reproducible fix for the reported game lag.
