AMD almost nailed Linux support with the Radeon RX 90 series — excluding FSR 4
Quoting: Gaming on Linux with AMD's RDNA 4 GPUs is a blast —
Gaming on Linux is now viable enough that there's little reason to keep Windows installed unless there's an app or service you absolutely must run on Microsoft's OS. The various Linux distros offer impressive gaming experiences, especially on AMD and Intel hardware. AMD recently launched the Radeon RX 90 series, and I played around with the RX 9070 XT using Fedora and version 6.13.5 of the kernel. AMD's Linux drivers are baked into the kernel itself, so nothing else was required to enjoy the latest and greatest AMD GPUs, aside from FSR support.
