Benchmarks: Civilization VI, Deus Ex: MD, DiRT 4
Civilization IV is another heavily requested title that I had ditched for my day one Vega coverage and you can see why from the results above: it's a bad game to test GPU performance. It's a great game to test CPU performance but as you can see here even with a heavily overclocked Core i7-7700K we are mostly finding the limits of the CPU. Again though, with 31 other games in this GPU comparison, adding Civilzation VI shouldn't skew the results.
Deus Ex: Mankind Divided is another DirectX 12 title but this one is far more GPU-bound and as luck would have it Vega does well here. This is of course an AMD sponsored title but even so it does show how well Vega can perform when a game has been optimized for it.
The Vega 56 came knocking on the GTX 1080's door here while the air-cooled Vega 64 model pulled ahead of the MSI GTX 1080 Gaming X 8G – the liquid-cooled version advanced well ahead.
Dirt 4 left me confused after my initial Vega 56 review but I have since been able to confirm these results. Vega does well using 2xMSAA and even 4xMSAA but tanks with 8xMSAA, though when I say tanks, I mean it drops down to the same level of the competing Nvidia cards. Using CMAA the Vega cards absolutely trash the GeForce 10 series in what is a completely baffling result. I've asked AMD about the various performance anomalies in this title with Vega but I've yet to hear anything back.
