Ubisoft has been notorious amongst gamers for their bad PC ports, something I’m going to get into detail during this AC Unity benchmark performance article.

Assassin’s Creed Unity like its predecessor is based on the AnvilNext Engine , a modified version of the Anvil Engine that goes as far back as 2007, when the first AC of the series was released.


Single and Multiplayer Features

Like previous installments in the series it’s an open world third person action-adventure where you play the role of an assassin in Paris during the French Revolution. Something different to this year’s game is the flexibility of customising Arno the main character and the skill tree, which allows the player to upgrade various skills like you would in a role playing game as you progress through the missions.

Another unique feature is the multiplayer co-op with up to four players, where you join friends to complete specific activities and missions.


System Requirements

To everyone’s amazement we have some very steep requirements as shown on Ubisoft’s official blog :

Intel Core i5-2500K @ 3.3 GHz or AMD FX-8350 @ 4.0 GHz or AMD Phenom II x4 940 @ 3.0 GHz

Intel Core i7-3770 @ 3.4 GHz or AMD FX-8350 @ 4.0 GHz or better

6 GB


Video Card
NVIDIA GeForce GTX 680 or AMD Radeon HD 7970 (2 GB VRAM)

NVIDIA GeForce GTX 780 or AMD Radeon R9 290X (3 GB VRAM)


Before the game was released to the public Ubisoft provided changelogs for two patches, as well as AMD and Nvidia being on top with optimized drivers and SLI/Crossfire support. I personally was surprised to be honest as we aren’t use to this kind of treatment for newer games. Sadly though I have delayed the benchmarks as there are various issues that haven’t been fixed even on the newer patch.


AC Unity

Patch 1.1.0

Using the 1.1.0 patch I had horrible performance in cutscenes with random crashes, stutter and framedrops as well as popins and visual glitches. The only way that I could get something half playable was to alt+tab out of the game and re-enter.


Patch 1.2.0

Downloading the 1.2.0 patch I thought at least some of the issues would be resolved. Well as you would guess no, other than the cutscenes being rendered at lower quality (so framedrops wouldn’t be as visible) and slightly less crashes it didn’t help my situation that much.

I’ve been trying every single possible solution from various forums as well as the official Assassin’s Creed blog to find a solution but everything seems totally random , something you don’t expect when paying a premium for a AAA title.

After trying to tackle this mess for three whole days with the 1.1.0 patch as well as yesterday’s 1.2.0 patch I’m going to be a little unorthodox with this benchmark. When there’s official SLI and Crossfire profiles I will put out charts for frame rate and frametimes with single and multi GPU results for the GTX970 and R9-290, but this time around I don’t have the patience nor willpower to go through what I have the last few days and will only be showing one setup with SLI GTX970s.


Benchmark Methodology

I picked Versailles in a very NPC heavy area to give a good indication of a performance hit to the benchmark system. The results were a street run of 60 seconds between the NPC crowds.

The benchmark was run in offline mode, as per Ubisoft recommendations.

For the 1920×1080 and 2560×1440 resolutions the Very High pre-set was used which consists of a mix of High, Very High and Ultra High settings with Ambient Occlusion on SSAO and Anti-Aliasing at 2xMSAA.


Ac Unity Graphics Quality


For 3840×2160 (4K) the Low pre-set was used with everything at the lowest possible setting and AA off.

Frame rate charts are from the Fraps minavgmax.csv file while the frametimes are again from Fraps but run through Frafs.

Note: The outcome was inconsistent running the same exact settings various times , your mileage should vary even if you have the same system.


Assassin’s Creed Benchmark Results

AC Unity 1920×1080 Benchmark

Strangely while we aren’t running the Ultra High pre-set our SLI GTX970 system is just able to keep up with over 65 FPS on average. The game does look great in some areas while in others the textures are just awful.

This isn’t the performance we would expect on other games at HD with this beefy of a system. The experience wasn’t perfect but the game was playable.

In our frametimes graph we see crazy variance. This isn’t multi GPU specific as running a single GPU gave us similar fluctuations.

As expected after seeing the 1920×1080 results bumping up the resolution to 1440 suffers a good 25% FPS average frame rate drop. The SLI GTX970s are just able to keep 46 FPS average with minimum frame rate hitting sub 40 FPS levels.

The frame times fluctuations are so noticeable while playing it’s a bad experience overall

Assassin’s Creed Unity 4K Benchmark

Trying to run 4K was a headache, while on the 1.1.0 patch the Low pre-set for the game was acceptable (the pre-set I was running while doing the initial missions) on the 1.2.0 patch it was a mess.

There were random drops to single digit FPS , with no VRAM bottleneck as we had everything turned down and no AA. It must be some kind of memory optimization issue. The 1 percentile and 0.1 percentile of frametime shows clearly there’s something going wrong here. We even had a moment where a single frame transition took 5400ms , a random 5 second delay while doing the benchmark.

You might be wondering where CPU, VRAM and system memory usage charts are. We didn’t add them for good reason as the results again are totally random. That’s the least of Ubisoft’s problems to be honest.

Similarly to what happened in our  AC Black Flag benchmark last year , Ubisoft are running an outdated and badly optimised engine. Adding better graphical settings, textures and throwing thousands of NPC on top of all that is only going to cause more issues.

As open world games are very demanding, there are going to be parts where textures look worse than a corridor shooter and everyone acknowledges that but there seems to be so much emphasis on things that have nothing to do with what gamers really want.

LOD is horrific and don’t forget the locked chests that need a forced mobile app and then microtransactions to open.

There’s similar problems in the PS4 and the Xbox One release. Digital Foundry covers the matter extensively here.

In my honest opinion there is no chance in *Paris* that Ubisoft can save this sinking boat, not even after multiple patches.

    The results vary so much that its hard to pinpoint whats really going on. If and when the game will be in a playable state I will get back and benchmark all the combinations of GPU’s I have available.

    For people using Nvidia cards a workaround would be to set AA in the Nvidia Control Panel and half refresh rate or adaptive vsync. For AMD users double vsync in Radeon Pro.

    FXAA or no AA on most setups will work and give you a slight fps increase. Be sure to lower enviroment textures if your not happy with the framerate aswell as boom off.

    4GB Vram seems to be maxed out on 4K high but that again might be a caching optimization issue.

  • SaberEdge

    Huh? The game runs great for me. Far better than I thought it would and not too much more demanding than most other recent multiplatform games on PC, yet Unity looks better than any of those games. It’s also much better optimized than AC4 Black Flag. It scales well and has good multithreading.

    The game is very much playable for me on a GTX 770. It runs at a very solid 30fps and looks amazing. I do have to lower textures from “ultra high” to “high”. I can only imagine how great it’s going to look once I get my GTX 980 next week and can run it with ultra high textures and a little downsampling.

    • Nikolas Nikolaou

      What resolution are you running, drivers and patch version?
      Is your Gtx770 a 2GB or 4GB ?

      • sokh1985

        Well it runs great for me too and even before they released patches (well not perfect but between 45 and 60 FPS with no big drops and i couldn’t go to 2 districts but that’s not performance related).

        And that’s with everything maxed out.

        Now it’s beautiful, and perfect. I’m running between 55 and 60 FPS @ 1080p

        I5 3570 OC to 4Ghz
        2x MSI GTX 970 Gaming 4G
        16 GB of DDR 3
        Game installed on 256 Gb Sandisk SSD Extreme

        Using Nvidia 344.65 and latest patch now.

        But gotta say since MSI Afterburner is telling me both card are used between 85 and 99%

        • Nikolas Nikolaou

          Actually testing out with FXAA on 2xGTX970 (1080p) the game is alot better to be honest. Moving up to 1440p its borderline imo.

          • sokh1985

            Well still strange since I have no issues with TXAA.

            But at least if FXAA is efficient enough for you aliasing-wise, then you can play it smoothly now.

          • Nikolas Nikolaou

            I will be updating the article with more combinations of GPUs if the 1.3 Patch plays well.

  • azroil

    i have the pirated version………..will try to download the gold edition

    • Nikolas Nikolaou

      We are against piracy, I was not provided a review code so I bought the game. If you enjoy the game please buy it.

  • Voidwalk3r

    Ubisoft is clearly run by a few mind fcked monkeys.

    • Nikolas Nikolaou

      After the new announcement with The Crew , things will change people are fed up.

      Also “To show our appreciation for your continued support, we’re making the upcoming Assassin’s Creed Unity Dead Kings DLC free for everyone. For Season Pass holders, we will also offer the choice of one additional game from a selection of Ubisoft titles for free.”

      • Voidwalk3r

        Do you think one small dlc worth all the f ups theyve done over the years? They continuously do this. Mark my words. It will be the same for the crew and the division. I said the same about the unity and no one believed me.

        • Nikolas Nikolaou

          They had to do something, anything basically. At some point they are going to have to change their ways, this reminds me a lot of EA and Battlefield.

          • Voidwalk3r

            After watch dogs i told people ubisoft wont change and this happened. Now i am saying it again. Ubisoft wont change, they are all about money and getting the games out whether its working or not.

  • lilbidS kanoS

    I am still downloading AC Unity. I want to know if I’ll be able to play it on my laptop. I have intel i-7 1.73 ghz (2.73 intel turbo boost), and geforce gt 425m 2gb, and 8gb ram. Will I be able to play it? If so in what settings? All other AC games worked fine. But I heard unity’s graphics is pretty high and that I’ll need better specs. Waiting for a quick reply. Thank you.

    • Nikolas Nikolaou

      You will probably be fine but, the game is a stutterfest in NPC filled enviroments and has strange slowdowns for no apparent reason on just about any system.

      • lilbidS kanoS

        Thanks for the quick reply. So glad that I’ll be able to play. But that slow downs will be annoying. But will have to cope with it. Thanks again.

  • piotr sitarek

    “Similarly to what happened in our AC Black Flag benchmark last year” It can’t be compared. Black flag was good at least on 1440p with only one mainstream card.

    • Nikolas Nikolaou

      The mention of similarity was due to the same core engine AnvilNext with “tweaks”. This time it’s just game breaking for most.
