Square Enix set the tone for Thief by saying, "Garrett, the Master Thief, steps out of the shadows into the City. In this treacherous place, where the Baron’s Watch spreads a rising tide of fear and oppression, his skills are the only things he can trust. Even the most cautious citizens and their best-guarded possessions are not safe from his reach." The Thief series has been popular for years, not only for its interesting story lines and unique gameplay, but because the games have consistently featured excellent graphics and imagery and leveraged bleeding edge technology, like AMD's Mantle API, for example.
The Radeons R9 Fury X was able to outperform the reference GeForce GTX 980 Ti at 4K in this test, but the factor overclocked GTX 980 Ti cards remained at the top throughout.
