Fix: Steam Deck Forza Horizon 4/5 Crashing, Stuttering, FPS drop

Playground Games are known for the Forza Motorsport video game, which includes top-rated titles such as Forza Horizon 4 and Forza Horizon 5. Though both the titles are doing well in graphics and gaming performance, some players are affected by the in-game issues you may also encounter. Here we’ve shared methods to fix Steam Deck Forza Horizon 4/5 Crashing, Stuttering, and FPS drop.

If we take a quick look at Steam Deck, it’s one of the best-suited all-in-one portable gaming handheld consoles that can easily run PC-specific video games. Valve Corporation has done a great job with Steam Deck, and the devs are also active enough to push system updates. However, some of the unfortunate Forza Horizon 4/5 players have difficulties with the game launching during gameplay sessions, etc.

Now, if you’re one of the victims to experience such issues on your Steam Deck then make sure to follow this troubleshooting guide completely. Now, without wasting any more time, let’s jump into it.

Press the Steam button from the left side of the Steam Deck.
Select Power > Choose Restart.
Once the device reboots, check for the issue again.

2. Force Reboot Steam Deck

You should force restart the Steam Deck manually by following the steps below if you still face the same issue. It’s better to force reboot Steam Deck if it’s powered on but unresponsive or stutters a lot. To do this:

Press and hold the Power button for at least 3 seconds. If it remains unresponsive, try long-pressing the Power button for around 10 seconds to reboot the system again forcefully.

3. Check for SteamOS Updates

An outdated SteamOS version can trouble you a lot regarding bugs, stability issues, security issues, etc. It’s better to check for SteamOS updates on Steam Deck manually by following the steps below.

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 there is an update available, tap on Apply.
Now, wait for the software update to complete.
Then tap on Restart to apply changes.

4. Check for Forza Horizon 4/5 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It can also be possible that the outdated game version is conflicting with the system to run properly due to some bugs.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 Forza Horizon 4/5 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 Forza Horizon 4/5, it’ll automatically install.

5. Check Internal 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 Forza Horizon 4/5 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

The chances are high that a corrupted MicroSD card on the Steam Deck may also trigger multiple issues with the Forza Horizon 4/5 game while launching it. So, it’s better to fully format the MicroSD card before 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.

Please 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’ve disabled the Steam Cloud Synchronization feature on your Steam Deck, then turn it on right now to properly cloud sync the game with servers. To do so:

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 highly recommended to forcefully change the Proton version on the Steam Deck by following the steps below because it can impact the game launching or performance a lot.

Select Forza Horizon 4/5 from Library.
Go to Settings of the game > Go to Properties.
Choose the Compatibility option in the left sidebar.
Make sure to click on the checkbox and select Proton Experimental.
You can now select the version you want to use.

9. Ensure Forza Horizon 4/5 is Verified on Steam Deck

Check if your Deck is verified or not for the Forza Horizon 4/5 game to play seamlessly without any further modifications. The Steam ‘Deck Verified’ system has four categories to indicate how well games will work on it.

Verified: The game works great on Steam Deck by default. No additional modification is necessary.
Playable: The game works, but may require some manual configuration from the user. 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 give it a try, but we don’t have any information about how it works.
