If you’ve ever wanted to grind for primogems, explore Sumeru’s rainforests, or take on weekly bosses while you’re commuting or away from your main gaming PC, you’re not alone. The Steam Deck’s portable form factor makes it a dream device for casual and hardcore Genshin Impact fans alike, but the game isn’t officially listed on the Steam store, so many players get stuck figuring out how to install Genshin Impact on Steam Deck. I’ve tested three different installation methods over the past six months, after growing tired of hauling a 15-pound gaming laptop on work trips just to complete my daily commisions. I’ve narrowed down the most reliable, low-fuss process that works for both 64GB and 512GB Steam Deck models, no fancy technical skills required.
Prep Work You Need to Do Before You Install Genshin Impact on Steam Deck
Before you start downloading anything, there are a few small checks you should run to make sure the installation goes off without a hitch. First, confirm you have enough storage: Genshin Impact’s current install size sits at around 80GB, and you’ll need extra space for future updates, so don’t cut it too close. If you have the base 64GB Steam Deck model, you’ll definitely need a separate memory card to fit the game. U3-class microSD cards are non-negotiable here; slower cards will cause long load times and random stutters when you’re moving between open world zones, so it’s worth spending a few extra dollars for a reliable option.
You’ll also want to make sure your Steam Deck is running the most recent software version, as old system files often cause Proton compatibility errors with newer game updates. You can check for updates in the system settings menu while in game mode, and the whole install process only takes 5 to 10 minutes if you’re behind. Here’s a full list of everything you’ll need before you get started:
Once you have all these items ready, hold down the power button on your Steam Deck and select “Switch to Desktop Mode” to begin the installation process. You don’t need a keyboard or mouse for any of these steps, but they can make typing in your account details faster if you have them handy.
The Simplest Installation Method for Most Users
The easiest way to get Genshin running on your Steam Deck is through the Heroic Games Launcher, a free, open-source tool available directly through the Steam Deck’s built-in Discover app store. Heroic is designed to run games from the Epic Games Store and GOG on Linux devices, and it automatically configures Proton compatibility for you, so you don’t have to mess with manual settings or download separate launchers.
To start, open the Discover app from the desktop taskbar, search for Heroic Games Launcher, and click install. Once it’s done installing, open Heroic and navigate to the Epic Games Store tab. Search for Genshin Impact, click install, and choose the storage location you want to use (either internal storage or your microSD card). The download will take 30 to 90 minutes depending on your internet speed, so feel free to step away and grab a snack while it runs.
Once the download is complete, you can add Genshin Impact directly to your Steam library from the Heroic launcher with one click. That means you’ll be able to launch the game directly from standard game mode, no need to switch to desktop every time you want to play. If you already have Genshin Impact downloaded on your Windows PC, you can transfer the game files to your Steam Deck via a USB drive to skip the full download, just make sure you place them in the correct Heroic game folder to avoid verification errors.
Performance Tweaks to Make Genshin Run Smoothly on Steam Deck
After installation, you’ll want to adjust a few settings to get the best balance of frame rate, visual quality, and battery life. First, navigate to Genshin Impact’s page in your Steam library while in game mode, click the settings icon, and go to compatibility. Select Proton Experimental as your compatibility layer; this is the most up-to-date version of Proton, and it fixes almost all common launch and crash issues for Genshin Impact.
Once you launch the game, head to the in-game settings menu to adjust graphics options. For portable play, set the resolution to 1280x720, turn off motion blur, set shadow quality to medium, and keep texture quality on high. Turn on the Steam Deck’s built-in FSR 2 upscaling in the quick access menu to get sharper visuals without dropping frame rate, and limit the refresh rate to 60fps. With these settings, you’ll get a steady 60fps in most open world areas, and you’ll get around 3.5 hours of battery life on a full charge, which is more than enough for a long commute or cross-country flight.
If you’re docking your Steam Deck to a monitor to play at home, you can bump the resolution up to 1080p, turn shadow quality up to high, and increase the TDP limit to 15W for even better visuals. The game runs perfectly docked, and you can use a standard PlayStation or Xbox controller if you prefer that over the Steam Deck’s built-in controls.
Common Installation Issues and How to Fix Them
Even with the most straightforward setup, you might run into a few small snags along the way. The most common issue I hear about is a download that gets stuck at 99% for longer than 10 minutes. If that happens, just pause the download, close Heroic, restart your Steam Deck, and resume the download. You won’t lose any of your existing progress, and it will usually finish within a minute or two of restarting.
Another common problem is the game refusing to launch after installation. This is almost always caused by a corrupted Proton prefix, and you can fix it by going to Genshin Impact’s settings in Heroic, selecting “Clear Prefix”, and running the verify game files tool. That will replace any missing or broken system files, and the game should launch normally after that. You don’t have to redownload the full game to fix this issue, so don’t delete your existing install files.
If your controller doesn’t work when you launch the game from Steam’s game mode, that usually means you added the game to your library manually instead of through Heroic. Heroic automatically configures a custom controller profile for Genshin Impact that works perfectly with the Steam Deck’s controls, so re-adding the game through Heroic will fix this issue immediately. You also don’t have to worry about account bans for running the game on Steam Deck: HoYoverse’s anti-cheat system explicitly allows Proton play on Linux devices as long as you aren’t using mods or cheats, so your account is completely safe.
Once you’ve got everything set up, you’ll be able to jump into Genshin Impact wherever you are, no bulky laptop or desktop required. Even if you’re not super tech-savvy, the entire process of how to install Genshin Impact on Steam Deck is way more straightforward than it looks at first glance, and the small amount of prep work pays off with hundreds of hours of portable open world fun. If you run into a problem that isn’t covered here, try checking community forums for the latest fixes, since Proton updates are released every few weeks to improve compatibility with new Genshin Impact version updates.
