Your information on the AMD Linux drivers is a few years obsolete. First off, even mentioning RadeonFB/DRI is out of date. Several years ago was replaced with AMDGPU-KMS/DRI for newer cards and RadeonSI-KMS/DRI for older cards. (The two are slightly different variants of the same driver. The two drivers use an interdependent codebase but now duplicate the code between the two drivers.) I would recommend the newest stable Mesa (Currently 13.3.3 as of this writing) and a minimum of release 13.x. This is the recommended requirements for Valve's SteamPlay. This should be the same for all Mesa based drivers. For an alternative driver, AMDGPU-Pro and AMDGPU-Open should be also recommended. They are both good drivers released directly by AMD. I have not kept up completely, but currently they have a few key features that the Mesa drivers don't have, but their performance isn't quite as good. The AMDGPU-Mesa is by far the best driver right now as of performance and reliability on OpenGL 4.5 applications. Additionally, there should be a note on experimental drivers that should be generic for all platforms and denote that any bug the slightest bit related to graphics should be checked without overrides, experimental options or unsupported drivers before reporting. I know that the Linux graphics driver development has accelerated drastically over the past few years, so it's no surprise if you can't keep up if you aren't personally following. I don't blame anyone for that. It's just what happens when technology moves fast. As a final note, you might want to discontinue the 32 bit binary and mark 8GB of memory as required, and 16GB recommended. This is actually getting quite common these days. I know it's better to fix all the memory leaks and hope that brings it down, but you'd still have 16GB recommended, and I doubt anyone is using the 32bit binary anymore.
