NVIDIA 381 Linux Beta vs. Linux 4.11 / Mesa 17.1 Radeon Comparison
Radeon does fairly well with ET: Legacy.
It's a pity the Radeon R9 Fury isn't more competitive in Metro Last Light Redux.
With Tesseract, however, the Radeon stack is competitive with the NVIDIA 381 Linux beta.
RadeonSI also does well with Tomb Raider.
