Metro Last Light Redux

Metro: Last Light is a single-player post-apocalyptic-themed first-person shooter video game with stealth and survival horror elements, developed by Ukrainian studio 4A Games and published by Deep Silver for Microsoft Windows, OS X, Linux, PlayStation 3 and Xbox 360 in May 2013. Just like the original game, Metro: Last Light is played from the perspective of Artyom, the player-character. The story takes place in post-apocalyptic Moscow, mostly inside the metro system, but occasionally missions bring the player above ground. Wikipedia

Both Metro 2033 and Metro Last Light have a built in benchmark utility which we used for both games.

  • Quality – Very High
    • SSAA – On
    • Texture Filtering – AF 16X
    • Motion Blur – Normal
    • Tesselation – Very High
    • V-Sync – Off
    • Advanced Physics – On
  • 3 Runs – 1 Scene

mll_fpsClearly this game with these settings is just too much at 5K resolution for any of these setups.  As any PC gamer will tell you 30FPS is not acceptable and even a fourth GPU wouldn’t boost performance close to 60FPS.

At these low frame rates though we would expect scaling to be quite good:

mll_scl

As usual Nvidia’s 3 way scaling is lower than it should be while AMD’s is close to perfect.  Let’s take a look at VRAM – with such low frame rates it might be easier to hide a VRAM problem:

mll_vram

Nothing to worry about here – what’s interesting is just how much more efficient AMD is here for memory usage.

Now let’s take a look at GPU usage.  We’d expect this to be consistently high:

mll_1f mll_2f mll_3f

As we can see although AMD’s gets its usual dropouts in utilization, they don’t always correlate to low FPS.

mll_1t mll_2t mll_3t

As usual the Nvidia plots are cleaner – at least for the first two setups.  Once 3 way SLI hits we see a lot of inefficiencies – interestingly the low utilization of GPUs does correlate to low FPS.  If the SLI performance was improved here Nvidia’s minimum FPS would no doubt be a lot better.

Clearly Metro Last Light Redux is going to need some settings turned down to play at 5K – even three Titan X’s can’t handle it in a playable fashion.

  1. To be honest, I started reading this article with a thought that “well, how good can it be? ERs are watercooling guys so, nah! can’t expect too much”. But after reading the whole of it, I have to say, This is by far the one of the best comparative reviews I’ve ever seen, and really met all my expectations. Hats off to you guys!

    Say, FuryX did have the claim in its pre-release rumor to be a TITAN X competitor, but then AMD shrunk that note to 980 Ti. So I think comparison with 980 Ti would’ve been better comparison (and seat clenching brawl) than this, and the clock-to-clock performance metrics but nonetheless, this is wayy too good also!

    About capping the vRAM on FuryX in few games there, it also suffers from similar performance degradation on 4K and downwards. And as you may have seen on other reviews, FuryX does worse in sub-4K than the competition and even worse in 1080p. I’ve dug through every review out there yet haven’t found the reason behind this. What could be the reason?

    And that scaling on nVidia – you know nvidia does claim that their SLI bridge isn’t a bottleneck, and so it is proved here :P. When AMD did introduce XDMA, I had this belief – AMD took the right path, bridges will suffer from less bandwith sooner or later, and PCIe already has the room for accommodating the data of the bridges. So XDMA did (well, now it is “do” :D) makes sense!

    But it’s sad to see AMD not delivering smoother experience overall. If they could handle that thing, this should certainly deserved the choice over any of those higher average FPS of Titan X. But I think AMD is working on Win10 & DX12 optimized drivers and trying to mend it with bandages for now.

    My only complain was the choice of TitanX over 980 Ti and clock-to-clock performance, but other than this, this is a very great review! Hats off to you again!

    • Agreed with Frozen Fractal. I was more than pleasantly surprised with the quality of this review, and I hope you continue to do these more in the future. A 980 Ti would have been nice to see too given the price.

      Keep up the great work!

    • Thanks! I agree the 980 TI would have been a better comparison – then prices would have lined up. “Sadly” we only had Titan X’s and we weren’t willing to go out and buy another 3 GPUs to make that happen. However if anyone wants to send us some we’d gladly run em haha. I was simultaneously impressed with AMD’s results while saddened that after all the work on frame pacing that things still aren’t 100% yet. Hopefully

  2. Question…you overclocked the Titan X to 1495MHz which is “ok” for a water cooling build. I won’t complain…though I’m surprised at why that’s all you were able to achieve as I can pull that off on Air right now (blocks won’t arrive until next week). Main question though…why wasn’t the memory overclocked? A watercooled Titan X has room to OC the memory by 20%, bumping up the bandwidth to 400Gbps, which brings it quite a bit closer to the 512Gbps of the HBM1 in the Fury X.

    • Although we didn’t mention it the memory was running a mild OC at 7.4Gbps up from the stock 7gbps 6gbps – so yes about the same as your 20% 🙂

      • This is what concerns me about your understanding of overclocking. The Titan X memory is 7GHz at stock. At 7.4GHz you’re only running a 5.7% OC on the memory…

        • Hah you’re right, I was looking at titan stock memory settings not titan x. Yes it could have been pushed harder. Still though single Titan X was really good compared to Fury X – the issue it had was scaling. So unless scaling is significantly effected by memory bandwidth then I don’t think it changes the overall results much. When we re-run with overclocked furies we’ll spend a bit more time on the Titan X overclock too.

          • Don’t get me wrong…SLI scaling is definitely an issue and will still exist regardless. But you’d be surprised how important memory clocks can be depending on the test you’re running. I found this out when I was running the original GTX Titan Tri-Sli in the overclock.net unigine valley bench competition and came in second place. Leave the official redo for your next review of Fury X OC vs Titan X OC, as you mentioned. But to satisfy your own curiousity, try a higher memory clock and see what happens. If you were looking to squeeze out every last ounce out of your Titan X, you should check out http://overclocking.guide/nvidia-gtx-titan-x-volt-mod-pencil-vmod/ as well.

            My Phobya nanogrease should be coming in tomorrow so I’ll finally be putting my blocks on as well. I’m going to compare my performance results with yours next time you run your benches. So make sure you do a good job. 😉

  3. Excellent review. I am also running an Asus Rampage Extreme V with a 5960x OC’d to 4.4Ghz so your data really was telling. I’m running a single EVGA GTX980TI SC under water. I previously ran 2 Sapphire Tri-X OC R9 290s under water but opted to go with the single card.
    Did you use a modded TitanX bios? What OCing tool did you use to OC the TitanX. I would like to try to replicate the parameters and run the single 980TI to see how close I am to your single TitanX data. Thank you.

  4. Eh, i don’t really see the point of running AA in 5K 😛 Too bad it’s 5K btw, 4K is more reasonable. Too bad Fury X has problems with the Nvidia titles(W3 for example).
    But man, the scaling and texture compression on amd cards are absolutely amazing. If only they weren’t bottlenecked by the HBM1’s 4GB of VRAM.
