Deus Ex: Mankind Divided (DirectX 12)
We tested Deus Ex Mankind Divided with higher graphical settings than usual and also in DirectX 12 mode, where we normally use DirectX 11 mode. That’s mainly because it was one of the few DirectX 12 benchmarks readily available. That led to some weird quantization in our results, but we think the data is still meaningful. See for yourself.
DXMD was actually one of the very first DirectX 12 games, so it’s no real surprise that it behaves strangely. The specific effect we’re seeing in the 99th-percentile frame times is not a bottleneck, but instead has to do with the way early DirectX 12 applications handled screen updates. In effect, the game’s frame-rate isn’t being limited as it would with old-school vsync, but it still isn’t able to present new frames any faster than the screen will show them. Given that we tested on a 60-Hz 4K display, that means the majority of frames were being presented in 16.7ms intervals.
So the good news is that if you intend to play Deus Ex Mankind Divided on a 60-Hz 2560×1440 monitor, you can enjoy perfectly-smooth vsync’d goodness using a Navi-based Radeon or any faster GeForce. Surprisingly, the RTX 2060 Super actually comes in a bit behind both Navi cards. Still, considering the weirdness in this benchmark we might be careful to ascribe too much meaning to it. In any case, its performance is still excellent; rather than the RTX 2060 Super being slower than usual here, the Radeon Navi cards are actually punching well above their weight class.
Going by our “time spent beyond” charts, a few things stand out. For one, every single card dips below 30 FPS at some point. You can see this clearly in gameplay; Deus Ex MD is simply not a very smooth game most of the time, even when running on a Ryzen 9 3900X off of a fast PCIe 4.0 SSD.
The threshold charts also confirm what we see in our average FPS measurements: the Radeon RX 5700 XT is running right alongside the GeForce RTX 2070 Super, while its slower sibling is consistently ahead of the RTX 2060 Super. An impressive performance from AMD’s latest and greatest.
