I recently built a new pc and since I switched from Windows to Lunux (Kubuntu) I got an amd gpu (6700 XT). Because people told me it is less of a hassle than Nvidia. It works fine out of the box, but the choice of drivers confuse me. For gaming is the default amdgpu good enough? Is amdgpu-pro the same as the official Radeon drivers from amd? Are they better for gaming? Is Mesa yet another driver or something in addition to a driver? Why are there no settings/gui anywhere (using the default amdgpu)?
For gaming, it works out of the box. You don’t need to install additional drivers. The other drivers are only necessary when dealing with things like machine learning and AI. They don’t offer better gaming performance and will only introduce problems similar to Nvidia.
Not only will the performance not be any better on amdgpu-pro, the performance will most likely be worse. Even AMD recommends that people who don’t need to do machine learning or AI work, use the built-in driver.
