Game development has a number of steps in it. It isn’t just artists visualizing their design and programmers dancing to their tune. There are two other important steps that makes sure that the game is highly polished and is performing up to an optimal level. The two steps are optimization and quality assurance. Optimization is essentially rechecking your code and assets, and brain storming to find faster and better ways to do the same thing. Quality Assurance is where the game is  tested across a number of parameters set by the the development team’s testers.

Unfortunately, it seems that Ubisoft skipped both of these highly important steps when developing the highly ambitious Assassin’s Creed Unity. We will get to the bad bits later but let us describe what Unity excels in. Assassins’ Creed Unity is perhaps one of the best looking games of all time. Its Physical Based Rendering and Global Illumination solutions lifts the visuals to an almost CG level and the animations are one of the best we have seen in video games. It’s an intriguing glimpse of what is possible with current generation of consoles and modern gaming PCs and a testament that games are very close to crossing the bridge that separates them from big budget movies.

However all of this is thrown out of the window when one actually sits down for a prolonged session with the game. This is not to say  that the entire game is broken but it is simply unplayable at times. It’s highly disappointing that a game with so much potential is bogged down with serious stuttering and frame rate issues. We first tested the PC version across two admirable sets of configuration.

The first configuration was an AMD 8350 4.0 GHZ CPU and R 290 GPU coupled with 16 GB RAM. We were expecting a stable 30 frames per second along with 1080p as the configuration was pretty close to the recommended settings by Ubisoft. Unfortunately we came across massive frame rate drops in our play through. In some instances the drops were as unexpected as 1 fps, literally forcing us to quit the game. At an average, we saw frame rates ranging from the low 20s to high 30s with plenty of stutter in between. Dropping the anti-aliasing from 8X MSAA all the way to FXAA made no improvements at all. However we found out that changing the Shadow quality to its lower settings made substantial difference with frame rate gains up to 5 and in some areas up to 10.

On the Nvidia side of things we tested the game on a GTX 680 and Intel I7 4930K. It’s important to note that Assassin’s Creed Unity officially supports Nvidia’s Gameworks so we thought a solid 60 frames per second at 1080p should be easily achieved. Fortunately, we were able to hit the golden standard with very few drops in between. However there was still a lot of stutter in between and the frame rate dropped to around 55 when there was a lot of crowd on the screen.

Enabling PCSS bought in performance issues but playing around with its setting helped the performance somewhat. In short, the performance on AMD cards was disappointing. The game is not scale able across both the configurations as lowering the settings did not allowed us to run at a constant 60 frames per second. This is a clear sign that the game has been poorly optimized on the PC. Players will need a very powerful GPU to keep it running above 60fps and given that a very small part of the gaming community will have access to such high end rigs, it’s correct to assume that Unity on PC is a reminiscent of Watch_Dogs’s disaster on PC.

The issues that we faced on PC were almost identical across the PlayStation 4 and Xbox One versions although we did find one instance where the PS4 managed to keep itself up. However it must be noted that the console versions do manage to keep it up at 30fps most of the times. Unlike Dragon Age Inquisition on consoles, HBAO is not present on the consoles as Ubisoft have opted for less resource intensive SSAO.

Both the consoles use post processing anti-aliasing solution which is a reminiscent of FXAA on the PC version. Both the console versions runs at 900p resolution which is surprising considering that the PS4 has a more powerful GPU and several multiplatforms games, including last year’s Assassin’s Creed IV: Black Flag, ran at 1080p on Sony’s consoles.

It must also be noted that in certain scenes, Xbox One seems to have a more crisper image. This is something which we also observed during our initial analysis as well. The players may not probably notice the difference side by side and as such this does not weigh much in our final verdict. The console versions also lack any sort of tessellation, however this will be covered in the PC version.

Other than the frame rate issues, all the three versions have identical mishaps such as the disappointing LOD and draw distance. The details on the characters change on the fly when Arno is walkthrough the streets. NPCs may appear all of a sudden and pop in issues are abundant. The draw distance is extremely disappointing and perhaps the worse in an Assassin’s Creed game. Given the modern technologies that developers have access to, it’s disappointing to see lack of any details in the far distance.

Switching back to the frame rate issues, Ubisoft claims that large crowds are not the reason behind the drops and going offline may resolve the issue. But doing so resulted into no difference at all in the frame rate and stuttering. Ubisoft claims that crowds are not a resource hog but why do we need so many NPCs is beyond our apprehension. Whatever beauty Unity has is diminished by the large crowds and their laughable LOD. I understand the need for utilizing all the modern processing power to push the boundaries further, but at what cost? Ubisoft could have saved a few more CPU cycles by adding an adequate amount of NPCs instead of mindlessly flushing them in.

In the end, Ubisoft’s Assassin’s Creed Unity is a technical achievement but only when your character is standing at one place. We would recommend the PC version should you have the muscle to pull it off but a locked sixty frames per second is simply out of the question. The PS4 version at times performs the best in intense scenarios but on the other hand the Xbox One has a crisper image quality. But as these differences are few and far between, we cannot recommend one version over the other.

Assassin’s Creed Unity was simply not ready for a launch. Ubisoft were brave enough to delay Watch_Dogs. Unity could have benefited by a couple of months of additional testing. But it seems that Unity in its current state is a Beta version and players are paying to test it.

    It’s because the CPU is holding the consoles back, I read 1 guy overclocked an i5 to 4.7 Ghz and that gave him a smooth experience with no stuttering or anything so seems cpu performance needs to be drastically improved, adding mantle would of mostly solved that on pc

    You guys should really take some time to do your research. Ubisoft clearly stated that the frame rate issues were due to CPU bound situations. There is no question that these issues should have been addressed before launch.

    P.S. You really need to check your grammar.

  • I’ve played it since launch and just beat it this week. In all that time, I have only encountered 3 major bugs on XB1. Still surprised to see this many people to have had such bad experiences with it since mine were really really great. Loved the game and the romance b/w Arno & Elise. I just wish they made Arno a larger part of the French Revolution like Conner was for the Revolutionary War. The French Revolution seemed more like a backdrop to the main story than it was a large part of it…

    I have both the ps4 version and xb1 version (if you wanna know why I’ll tell you) I sent about 4 hours playing on ps4 before getting the xb1 version and now I play just the Xbox version. Visuals are identical from a quality standpoint BUT the Xbox version definitely runs better, has less draw in, less NPC pop in and waaaaay less bugs all around. On ps4 I’d constantly see NPC’s pop in and often then would appear about a foot off the ground and then they would drop. It was odd and distracting but the frame rate is the ps4’s biggest issue. Its bad. Gddr5 is great for graphics but not so much for CPU bound tasks like AI.

    Ubi says cutting crowd sizes doesn’t impact performance but that can’t be true. removing 20 NPC’s from a scene should clear enough overhead to lock the game at 30. If not then remove more. as nice as it is seeing tons of characters I’d much rather have a smooth game.

    I’d love to play this on PC at 60fps. It would be so much better. The amazing animation of this game is lost at 30fps especially when it starts dropping frames.

    i dont understand this, when people say the game is poorly optimized, that would be related to the stutters and fps drops. but saying that such beautiful gfx doesnt need powerful hardware is a stupid statement, that pc elitists should get out of their heads, ( this coming from an owner of a gtx 980)

    Try using an nVidia card in the PC instead of the crippled version running on AMD hardware.
