Assassin's Creed Odyssey PC Performance Report and GPU Benchmarks
By Jon Sutton on October 5th, 2018 at 04:15pm - original article from game-debate

We've already delved into the performance hit of each and every Assassin's Creed Odyssey PC graphics option, but now it's time to see how Ubisoft's Grecian adventure actually performs. 2017's Assassin's Creed Origins was notoriously demanding, with more than a few fingers pointed at the multiple layers of DRM.

Assassin's Creed Odyssey arrives with a slight bump in PC system requirements, meaning we're expecting a more demanding game overall. At the very least, matching the console performance needs to be achieved though, so let's see how AC Odyssey's PC performance pans out in a series of benchmarks.

Assassin's Creed Odyssey System Requirements

Assassin's Creed Odyssey Benchmarks

AC: Origins benchmarks and frames per second analysis performed on GeForce GTX 1060 6GB | Intel i7-5820K | 16GB DDR4

For this Assassin's Creed Odyssey benchmark, we used a GeForce GTX 1060 equipped with 6GB video memory. This is slightly more powerful than the recommended GPU, a GeForce GTX 970, which Ubisoft suggests is good for playing at 1080p/30fps. It’s backed up by 16GB DDR4 memory and an Intel Core i7-5820K CPU.

Assassins Creed Odyssey GeForce GTX 1060 6GB 1080p, 1440p and 4K Benchmarks

  1080p 1440p 4K
Low 82 59 34
Medium 69 50 30
High 57 42 24
Very High 50 38 20
Ultra High 40 33 17

The results tell us that Ubisoft was perhaps slightly overestimating the system requirements for AC Odyssey. While the GTX 1060 is a notably faster card than the GTX 970, it's almost doubling 30fps @1080p/High that Ubisoft suggests for the GTX 970. This may all come down to VRAM usage, but on this basis, any card with a decent amount of VRAM (4GB GDDR5+) should at least be able to match console frame rates.

Aside from this, we can also see Assassin's Creed Odyssey is an immensely demanding game. The GTX 1060 6GB is rarely ever troubled at 1080p, yet those hoping to hit a locked 60fps will have to make some serious sacrifices. If, indeed, that's even possible at all. During our tests, even at Low/1080p, the GTX 1060 hit a minimum frame rate of 34, and a maximum FPS of 145. Not only is this a massive tumble from 60fps, it can also create a lurching feeling as the frame rates flap all over the place. Our recommendation would be to attempt to lock the frame rate of Assassin's Creed Odyssey in-game.

For this ACO benchmark, we used a GeForce GTX 1070 equipped with 8GB video memory. It’s backed up by 16GB DDR4 memory and an Intel Core i7-5820K CPU.

  1080p 1440p
Low 93 75
Medium 81 65
High 69 54
Very High 61 47
Ultra High 53 40

Even the once mighty GeForce GTX 1070 8GB takes a few stumbles in our Assassin's Creed Odyssey benchmarks. This 1440p beast can hit a lot of snags at its optimum resolution, not actually emerging a great deal faster than the GTX 1060 6GB. Yet again, frame rate dips are prevalent depending on the on-screen action, and those after 60fps may have to consider dipping down to 1080p. A locked 30fps at 1440p is theoretically achievable, but there's a sense of disappointment in paying for a $400 GPU and playing at 30 frames per second.

Is Assassin's Creed Odyssey more demanding than AC Origins 2016? 

The obvious question now is, has anything actually changed since last year? It's only been about 11 months since we got our hands on Assassin's Creed Origins, which isn't a very long time at all. It will have been completely different studios working on this one, but there's been scant time to improve either the performance or the visuals.

As you can see, there is no definitive answer to be found here in terms of which game runs better on this particular setup. However, the results paint us quite a picture, possibly hinting at AC Odyssey being better optimised in terms of CPU usage, but otherwise being more demanding on the GPU. 

Looking at the Low benchmarks, this is typically where we'd expect the CPU to exert any sort of bottleneck. Across both benchmarks on Low we see that AC Odyssey actually runs better than AC Origins; somewhere in the region of 5-10% higher frame rates are achieved.

As we scale up the visuals though, the roles begin to reverse, with Assassin's Creed Odyssey a far more demanding game to run at High graphics settings and above. This is where the graphics card needs to do most of the heavy lifting, and once we get down to Ultra there's a hefty 20% gap between the two games in terms of performance, a 30% swing compared to Low.

Naturally, this does raise a few questions about CPU performance in Assassin's Creed Odyssey, and we'll plenty more on that shortly.
