There’s nothing quite like the stealth-action thrill of Splinter Cell Conviction, but trying to run this Ubisoft classic on a Steam Deck can be a mission impossible of its own. Many players face the frustration of the game crashing immediately or getting stuck on the infamous Ubisoft Connect launcher. Despite these technical hurdles, playing as Sam Fisher on a handheld device is an incredible experience that is well worth the few minutes of setup required to get it running perfectly.

Why This Happens?

The primary reason Splinter Cell Conviction is labeled as “Unsupported” or “Borked” on Steam Deck is due to the outdated version of the Ubisoft launcher bundled with the game and specific Windows-only video codecs that standard Proton versions struggle to translate. These issues typically lead to a “Black Screen” on launch or a complete system hang when the game tries to communicate with Ubisoft’s servers.

The Fix: Step-by-Step Guide

To bypass these crashes and ensure a stable frame rate, we will use Proton GE (GloriousEggroll). This custom compatibility layer includes specific patches and media foundations that aren’t available in the official Valve versions of Proton.

Step 1: Install ProtonUp-Qt Switch your Steam Deck to Desktop Mode. Open the “Discover” store, search for ProtonUp-Qt, and install it.
Step 2: Download the Latest Proton GE Open ProtonUp-Qt, click “Add version,” select “Proton-GE” from the dropdown, and install the latest available version.
Step 3: Force Compatibility Mode Return to Gaming Mode. Go to the game’s Properties > Compatibility. Check “Force the use of a specific Steam Play compatibility tool” and select GE-Proton.
Step 4: Launcher Workaround On the first launch, let the Ubisoft Connect launcher update. If it hangs, simply restart the game; Proton GE will handle the next attempt much better.

Optimization Settings for Steam Deck

To achieve a stable 60 FPS and extend your battery life, use these recommended in-game settings:

Setting	Recommended Value
Resolution	1280×800
Graphics Quality	Medium
Shadow Quality	Low
Anti-Aliasing	Off
Texture Quality	High

Pro Tip: Limit your Steam Deck Refresh Rate to 60Hz/60FPS via the Quick Access Menu for the smoothest experience.

Conclusion

With the power of Proton GE, Sam Fisher’s journey becomes fully playable in the palm of your hands. This setup fixes the launcher crashes and ensures the cinematic interludes play without a hitch.
