Insalling additional drivers will ensure that you have the best performance and compatibility with your games. See here for more information.
Nvidia
yay -S nvidia-open-dkms nvidia-utils lib32-nvidia-utils nvidia-settings vulkan-icd-loader lib32-vulkan-icd-loader
Note: nvidia-open-dkms supports Turing (GTX 16xx / RTX 20xx) and newer GPUs. Pascal and older cards need the legacy nvidia-580xx-dkms package instead.
AMD

Intel
yay -S lib32-mesa vulkan-intel lib32-vulkan-intel vulkan-icd-loader lib32-vulkan-icd-loader
Note: for Intel integrated graphics users: Only Skylake and newer Intel CPUs (processors) offer full Vulkan support. Broadwell, Haswell and Ivy Bridge only offer partial support, which will very likely not work with a lot of games properly. Sandy Bridge and older lack any Vulkan support whatsoever.
