The Nano averaged 30fps in Dragon Age Inquisition at 4K, 6% slower than the Fury and 7% faster than the R9 390X and GTX 980.
At 4K in The Witcher 3: Wild Hunt the Nano was good for just 27fps, 4% (a single frame) slower than the Fury, 17% faster than the R9 390X and 23% faster than the GTX 980, which is surprising as we tested with HairWorks enabled.
