Deus Ex: Mankind Divided DX11 Video Card Benchmarks

Deus Ex: Mankind Divided Graphics Memory Usage

Using an NVIDIA GeForce GTX 1080 8GB Founders Edition graphics card we ran the games built-in benchmark to see how much memory (frame buffer) was being used at various image quality settings.

Deus Ex: Mankind Divided Image Quality Settings

For this section of the article we’ll be looking at high, very high and ultra preset we disabled VSync and left MSAA off. The differences between each image quality preset setting can be seen in the second screenshot above.

We’ve seen on Steam that many gamers are reporting performance issues when playing Deus Ex: Mankind Divided on Very High/Ultra settings with MSAA set to 2x, 4x, or 8x. This game title is very demanding with MSAA turned off. If you are experiencing performance issues, here are a few workarounds you can try out for now:
– Turn off MSAA
– Turn off Contact Hardening Shadows
– Keep Volumetric Lighting to on or off
– If you have a 4GB GPU, keep settings up to High
– Keep resolution to 1080p
– Enable Exclusive Fullscreen
Deus Ex Mankind Divided Frame Buffer Usage

As you can see from the frame buffer usage chart, Deus Ex: Mankind Divided has pretty decent memory requirements. When using High image quality settings we see that it uses a full 2GB of frame buffer at 1080P and moving up Ultra image quality settings used close to 3.6GB of memory. The good news is that most recent video cards have over 3GB of memory on them. For example the NVIDIA GeForce GTX 1060 3GB has enough frame buffer to play Deus Ex: Mankind Divided at 1080P at high or very high image quality settings without issues. If you play on a 1440P display you’ll want to have at least 3GB of video card memory and ideally 4GB. For the 1% of gamers that have a 4K gaming display you’ll be used over 5.5 GB of frame buffer with ultra image quality settings. Most of the AMD and NVIDIA flagship video cards have 6-8GB of memory on them, but there are cards like the AMD Radeon R9 Fury X that have just 4GB of memory.

Since we tested three different image quality settings on the NVIDIA GeForce GTX 1080 8GB Founders Edition graphics cards we might as well show you the benchmark results as well. Here you can see that the GeForce GTX 1080 FE is best run with ‘Very High’ image quality settings in Deus Ex: Mankind Divided as the minimum frame rate never dropped below 60 FPS. This is a very demanding game title as the GTX 1080 could barely average 60 FPS with the Ultra present on a 1080P display.

When moving up to the popular 2560 x 1440 display resolution you can see that the NVIDIA GeForce GTX 1080 8GB Founders Edition can’t average 60 FPS on the top three image quality settings. You can average 60 FPS on medium settings, but there is a pretty significant difference between low/medium and high/very high/ultra. You buy a high-end card like the GeForce GTX 1080 to crank up the image quality settings and not run games at medium IQ settings!

Running Deus Ex: Mankind Divided on a single GeForce GTX 1080 8GB graphics card with the reference clock speeds will give you 30 FPS with high image quality settings. Here is an example of a game title that a single NVIDIA GeForce GTX 1080 can’t handle at 4K with decent image quality settings. You’ll need to run a multi-GPU SLI setup or reduce the image quality settings to low to be able to run this game title at 4K resolutions.

Now that we know more about the frame buffer needs of Deus Ex: Mankind Divided, let’s take a look at performance of a handful of cards at ‘High’ image quality settings. We picked to run just ‘High’ image quality settings due to how tough this game title is to render and we feel that most gamers will try to target this setting.

    Seems like AMD cards are having a much easier time with this game, even in DX11… fishy. I’d understand in DX12, but not in DX11. I expect the gap to widen even further in DX12 between the 2 vendors.

    I just installed GTX1080 and I when I did benchmark and saw 51FPS on 1440p on Very High I was 100% sure that something is wrong and those results can’t be true.
    I’m glad I came here before changing pci slots and reinstalling all the drivers etc. but it truly is terribly optimised game..

    • Nathan Kirsch

      Yeah, could just be a bad port. Really excited to see what the DX12 patch will do for PCs. Open up GPU-Z when you are bored… You’ll see it performance capped for pretty much ever reason possible.

  • Barnassey

    What a shitty review. You included a 780 Ti but not a 970?

    • Nathan Kirsch

      Sure don’t want this to be a shitty performance review, so I added a GeForce GTX 970 for you!

      • VelvetShadows

        I laughed, but I’ll give you credit for running all the tests on an additional GPU just to appease someone who insulted you.
        The 780TI is usually a pretty good proxy for GTX970 performance anyway, they seldom perform much different

        • Barnassey

          It really shouldn’t, the compute difference between the two is rather large. I owned one and i can say that with a good deal of confidence.

      • Barnassey

        Well I feel really stupid now. Thank you for adding the 970.

        • Nathan Kirsch

          No problem! Always happy to add a card if I have one here. I know the GeForce GTX 970 was the most popular card of the 900 series, so it makes sense to include it.
