Than you for the reply, JackE. I have the Acer PH315-55s-SL93Z Predator Helios 300 SpatialLabs Edition laptop and I have bought and downloaded Forza Horizon 4 from the Microsoft store.

Hi JackE,

The games has been installed correctly and works in 2D.

The problem is that it not is detected by the True Game application.

I have noticed that other users have similar issues with various games.

Assume that this is a bug or specific settings have to be done to get the games to work.

The workaround for Forza Horizon 5 does not work with Forza Horizon 4. The TrueGame app does not recognize Forza Horizon 4 after I have launched it in 2D and changed settings to default. Btw, I also have Forza Horizon 5 and it works fine in 3D.

There was feedback in another thread that the TrueGame supposedly will recognize supported games if they are recognized by the GeForce Experience app. In my case, both Forza Horizon 5 and Forza Horizon 4 are recognized by the GeForce Experience app, but for some reason Forza Horizon 4 is not recognized by the TrueGame app.

Forza Horizon 4 works fine in 2D when launched directly outside the TrueGame app. The Acer hardware also works fine.

The problem is in the TrueGame app which has been developed by Acer.

I doubt that anybody from the Forza Horizon 4 forums can help with troubleshooting for it.

Acer is the company which offers the TrueGame app. Hence, it is their responsible to provide bug fixes and/or proper instructions for how to use it.

I have the full bundle that covers Forza Horizon 4, Forza Horizon 5, and all expansion packs.

Did a full reinstall and tried to install the standard version of Forza Horizon 4 to see if it would make any difference. However, the TrueGame still doesn't recognize the game.

First a full reinstall of Windows from the hidden factory reset partition and then a clean installation of the FH4 standard version.

Hi JackE,

Thank you very much for sharing the links. I really appreaciate you support. Especially considering that you not are Acer Tech or a customer service support rep.

I was looking for a download location for the specific drivers and applications for the Acer PH315-55s, so the link was a big help.

Let me try to reinstall it and see if it helps and alternatively wait for the update of the Spatiallabs Experience Center which was supposed to be out in late January. Hopefully, it is just around the corner.

I have also had a chance to test a couple of other games. Shadow of the Tomb Raider and God of War work without any issues. The 3D experience is excellent in these games. I am really starting to think that it was worth the purchase and I hope this technology is going to get wider attention and reach to a broader audience in the near future.

Unfortunately, a reinstall of the Spatiallabs Experience Center including the TrueGame application didn't solve the issue.

I managed to get the TrueGame application to discover FH4 automatically by manually adding the search path in the settings.

However, I get an error message when launching the game saying (see screenshot below):

3D activation failure. Failed to launch the game in stereo 3D mode. Error code: 1

I have a feeling that the issue might be related to security settings and access permissions because FH4 is installed in a hidden subfolder called WindowsApps inside the Program Files folder. It was necessary to change the access permissions for the WindowsApps folder in order to become able to open it as default access permissions were system only. Other Microsoft GamePass games are installed in a non-hidden folder called XboxGames which is located in the root of my C-drive that I freely can access without change of access permissions.

I think there is no choice but for me to find a way to report the issue directly to Acer or hope the issue will be fixed with the expected update for the Spatiallabs Experience Center. I have high hopes for the update as it supposedly is going to include a new 3D Ultra mode. More info available at the following link:

Btw, I have also been playing around with more of the games which are supported by the TrueGame application as several are available with a standard Microsoft GamePass subscription. Several failed to launch with default settings but start working after I have launched them in 2D and adjusted the video settings. Typically, the games must be configured to run in full screen mode in max resolution of 3,840 x 2,160 with V-sync set to 60hz. I have tested various different video settings in FH4 but continue to get the above-mentioned error message.

The TrueGame application has finally been updated to version 0.7.74.0. See screenshots below. I can confirm that several games now are available in the 3D Ultra mode with massive improvements. Shadow of the Tomb Raider and Kena: Bridge of Spirits are now a much more fluent experience and pleasant to look at. I do not get any eye strain from them and there is no longer any visible screen door effect to me. There are also more new games. It is not all games that are available in the new 3D Ultra mode and FH4 is still not working. I will patiently wait for further updates and enjoy the improvements that came with this one.
