LinuxQuestions.org - OpenSuSE Tumbleweed: AMD Radeon RX Vega 64 [3D graphics hardware acceleration]

I own a mid-2017 AVA Direct pre-built gaming desktop PC intended for Microsoft Windows 10 Pro 64 bit and I recently installed OpenSuSE Tumbleweed 64 bit GNU/Linux as my sole desktop operating system. I chose the BTRFs for the /root partition and EXT4 for my separate /home/wellywu partition because I have an Intel 6000p 512GB PCI-e NVMe SSD and the default XFS will cause input/output errors for my personal folder.

Here is a code dump:

As you can see, 3D hardware acceleration is "turned on" using LLVM 5.0 and usage of the VMWare software graphics vendor. I posted a thread on the OpenSuSE community forum and nobody replied so I got frustrated and I decided to post here.

In a nutshell, how do I turn on true 3D graphics hardware acceleration so that I can play my SteamOS + GNU/Linux PC game titles?

Do I have to add my wellywu account to the video group?
Do I need to modify my X.Org configuration file?
Do I need LLVM 6.0?

In plain English, how do I get true 3D graphics hardware acceleration to just work?

Thank you.
