This article targets graphics cards of Turing (NV160/TUXXX) and later models. You can check your graphics card model with lspci -k | grep -A 2 -E "(VGA|3D)"

On the Linux platform, Nvidia drivers are divided into 3 types:

• nvidia/nvidia-dkms Nvidia official proprietary driver
• nvidia-open/nvidia-open-dkms Nvidia official semi-open source driver
• nouveau Third-party open source driver

The official drivers, whether proprietary or semi-open source, perform much better in gaming than third-party open source drivers. The difference between versions with and without the dkms suffix is that versions without the suffix are for the standard Linux kernel, while versions with the suffix are for other kernels.
