Forza Horizon 4 can be an extremely taxing game to run on your device, and a dedicated GPU is almost a must to ensure a good level of resolution and frame rate. In case your game is not using the GPU it should be, it could lead to some serious problems. Let’s take a look at how you can fix this.
In case you use an NVIDIA graphics card, you have two options. Either you could go into the NVIDIA control panel and look for Forza Horizon 4, and right-click on it. Here, select the option “Use [Graphics Card name]” instead of “Use Global Settings”. This should make the game use your dedicated GPU. If you are using a laptop and not a PC, make sure you are plugged in at all times. You can create a new power plan for the game by searching “power plan” in the windows search bar. Make sure you set performance to “high’ and use this plan when you are running the game. Furthermore, consider using an ethernet connection to ensure you are running the latest update version of Forza Horizon 4.
There is a chance that your third party or Windows antivirus software may be causing the game to misbehave. Temporarily suspend these services and see if that fixes the problem. If you are not comfortable doing this, you can reach out to your security provider and ask them if the service might be interfering with Forza Horizon 4.
Click on start and open up your Settings. Click on “Update and Security” and then “Windows Update” from the left sidebar. Click on the “Check for Updates” button, and windows will automatically find and install all the latest updates to your device drivers including your desktop, printer, mice, etc. Alternatively, you can do this from the Device Manager individually. Try to launch your game and see if it’s using your GPU now.
