- Press the Steam button on the left side of the Steam Deck.
- Go to Settings > Head over to the System tab.
- Select Check for Updates on the right side > If an update is available, tap on Apply.
- Now, wait for the software update, and tap on Restart to apply changes.
4. Check for Witcher 3 Updates
It can also be possible that the outdated game version is conflicting with the system to run properly due to some bugs. You should check for the game update by following the steps below.
- Open your Steam Library > Under the Witcher 3 library page, select Manage.
- Choose Properties > Select the Updates tab.
- Make sure to select Automatic updates > Reboot the Steam Deck.
- Whenever a new update is available for Witcher 3, it’ll automatically install.
5. Check Onboard Storage Space
You should also check for the available data storage space on your Steam Deck because low disk space can cause several issues with the Witcher 3 launching and performance. Just press the Steam button on Steam Deck > Go to Settings > Choose Storage. If the available storage space becomes low, delete or uninstall unnecessary apps/games from the console to free up some space.
6. Reinsert the MicroSD Card
Sometimes a corrupted MicroSD card on the Steam Deck console can also cause multiple issues, with the Witcher 3 game crashing during startup. It’s worth mentioning that you should fully format the MicroSD card before start using it with your Steam Deck. To format a microSD card:
- Make sure to properly insert the MicroSD card into the memory slot on the bottom side.
- Press the Steam button on Steam Deck > Go to Settings.
- Choose System > Select Format SD Card.
- It may take a couple of minutes to complete the format.
Note: Any UHS-I (class 3 or better) microSD card is supported. Steam Deck does not support UHS-II. If your MicroSD card is older enough or gets corrupted often, it’s time to get a new One.
7. Enable Steam Cloud Synchronization
If you have somehow disabled the Cloud Synchronization feature earlier on your Steam Deck, then you should enable it to properly cloud sync the game with servers.
- Press the Steam button > Select the Steam menu at the top-left corner.
- Go to Settings from the list > Navigate to the Cloud tab.
- Checkmark the Enable Steam Cloud Synchronization box.
- Select OK to save the changes.
- Once done, restart the Steam Deck to apply changes.
8. Force Change Proton Version on Steam Deck
It’s also highly recommended to forcefully change the Proton version on the Steam Deck by following the steps below because it can greatly impact the game launching or performance.
- Select Witcher 3 from Library.
- Go to Settings of the game > Go to Properties.
- Choose the Compatibility option in the left sidebar.
- Make sure to tick mark the checkbox > Select Proton Experimental.
- You can now select the version you want to test out.
9. Ensure Witcher 3 is Verified on Steam Deck
Check whether your Deck is verified for the Witcher 3 game to play seamlessly without further modifications. The Steam ‘Deck Verified’ system has four categories to indicate how well games will work on it. If a game is Playable or Unsupported, you can see what requirements of Verified are not currently met by referring to the Steam Deck Compatibility section on the game’s Steam Store page.
- Verified: The game works great on Steam Deck by default. No additional modification is necessary.
- Playable: The game works, but the user may require manual configuration. This could include adjusting controller configurations or using a mouse or touchscreen to navigate a launcher.
- Unsupported: The game is currently not considered playable on Steam Deck.
- Unknown: We haven’t tested this game for compatibility yet. Feel free to try it, but we don’t have any information about how it works.
10. Reinstall Witcher 3
It’s better to uninstall and reinstall the Witcher 3 game on your Steam Deck by following the steps below. The chances are high that reinstalling the game might fix several conflicts or issues with launching for sure.
- Press the Steam button on Steam Deck to open Settings.
- Scroll down in the sidebar and select Storage.
- Select the Witcher 3 game that you want to uninstall.
- Now, press the X key to Uninstall the game.
- Wait for the game to be deleted completely.
- Once done, reinstall the Witcher 3 game via the Steam Store again.
11. Factory Reset Steam Deck
You should also perform the factory reset method on Steam Deck to delete all the data and settings to the default state. It can also help you to fix crashing issues with the game. To do so:
- Press the Steam button on Steam Deck to open Settings.
- Under the System menu, scroll to the bottom and select Factory Reset.
