interesting, have you tried starting Xorg without a configuration in 
place?  on my intel systems not having a config in place has Xorg 
utilize the modesetting driver, which gives me full hardware 
acceleration.  i believe this should also work on amdgpu as well 
(although i'm less familiar with that GPU).  you may have to remove the 
xf86-video-amdgpu pkg to see if it can load modesetting.

also, with your current config does "glxinfo" show support for the 
missing extensions?  interestingly enough I do not see support for 
GL_EXT_shared_texture_palette nor GL_NV_register_combiners on my intel 
system.  it' been a while since i've done any 3d work so I'm not %100 
sure of the criticality of those last two extensions are.
