Assassin’s Creed Mirage on Steam Deck – Best Settings

Assassin’s Creed: Mirage is Ubisoft’s latest release, in which the developers partially return to the roots of the long-running series, but at the same time use many modern mechanics. If you’re curious about how the game runs on Steam Deck, check it out!

I tested the game directly on Ubisoft Connect, and installed the program with the help of the Non Steam Launchers script. All the footage was created on SteamOS 3.5. I observed that the game had slightly worse performance after setting the 4GB UMA Frame Buffer Size in the bios, so I went back to the default 1GB. I also use Cryobyte Utilities and have not made any changes there. I don’t recommend installing the game on a memory card, as the loading times are noticeably longer, and there is additionally less stutter on the SSD.

I happened to crash Steam Deck in this game, and I had a similar issue with Assassin’s Creed Valhalla installed via Ubisoft Connect. The issue was fixed by disabling the overlay.

The most important information is that Assassins Creed Mirage is very playable on Steam Deck. Of course, we can’t afford high graphics settings, but on medium quite stable 30 frames per second is within reach. I will say more – if you are using an unlocked screen refresh rate then 35 Hz is the best option for this game in my opinion.

Assassin’s Creed Mirage – Steam Deck best settings

SCREEN:

FPS LIMIT: DISABLED
WINDOW MODE: BORDERLESS
VSYNC: ON

GRAPHICS:

WORLD DETAIL: MEDIUM
CLUTTER DESTINY: MEDIUM
SHADOWS: MEDIUM
VOLUMETRIC CLOUDS: MEDIUM
WATER: MEDIUM
SCREEN SPACE REFLECTIONS: MEDIUM
ENVIRONMENT TEXTURES: HIGH
CHARACTER TEXTURES: HIGH
DEPTH OF FIELD: LOW
MOTION BLUR: ON
ADAPTIVE QUALITY: OFF
UPSAMPLE TYPE: AMD FSR 2
UPSAMPLE QUALITY: QUALITY

I tested all the options and exactly in this form I achieved the most stable performance. In addition to AMD FSR 2, the game additionally has scaling from Intel too, but you will get worse performance and additional ghosting on it.

Due to CPU limitations, even on the lowest details I couldn’t achieve a stable 40 FPS, so as I mentioned earlier, I recommend playing at 30 or 35. Try it for yourself, but for me the FPS drops in the more populated areas were too high.

The Bazaar location is the most demanding of the entire game, and as you can see, even there it holds solid fluidity. From time to time there are minor stuttering, which I have not been able to eliminate, and they also occur on high end PCs. These are not major problems and did not seem to bother me. During battles I didn’t notice more frame drops.

Running time on my settings should give you  about 2 hours of gameplay. Assassins Creed Mirage has full gamepad support, cloud saves and the ability to increase the size of subtitles and interface. 

I think it’s a very solid launch and if you plan to play it on Steam Deck you won’t be disappointed. The game looks nice, runs quite smoothly and has all the key elements that improve the gaming experience on a handheld. What’s more, Assassins Creed Mirage is available on Ubisoft+ subscription, so you can check it out much cheaper. I completed the game in about 20 hours, which for many people should be achievable within one month.
