The reason keeping me from switching over to Linux is because I have a low end laptop GPU (AMD R5 M300 series) and every drop of OC is vital to me, I used MSI Afterburner on Windows and I don’t know what to use on linux that actually work and user friendly if possible
No matter which distro you actually use, the ArchWiki has a detailed section on overclocking AMD GPUs, including manual OC as well as a list of several CLI and GUI tools.
That said, I’ll second the recommendation of corectl if you’re looking for something user-friendly.
