With the slowest gfx settings, the game "ARK: Survival Evolved" starts on my
computer though it's too slow to be played.

That said, the logs is repeating these 2 errors:
steam.desktop[23285]: EE r600_shader.c:158 r600_pipe_shader_create -
translation from TGSI failed !
steam.desktop[23285]: EE r600_state_common.c:766 r600_shader_select - Failed to
build shader variant (type=1) -1
