How to Fix If Arma 3 Not Using GPU
In most scenarios, such issues might gonna appear whenever the specific game doesn’t use the dedicated or external graphics card on the PC. Well, that doesn’t mean your graphics card isn’t working or it has some issues. Though the graphics card is working fine and it’s connected properly, sometimes the game itself has some configuration issue that you’ll have to adjust manually. So, without wasting any more time, let’s jump into it.
1. Use a Dedicated Graphics Card
Make sure that your computer system is actually using the dedicated or external graphics card to run the Arma 3 game. It’ll eventually reduce game stutters, lags, and frame drops without any doubt. If you don’t know which settings you need to adjust then follow the steps below.
If you’re using the Nvidia graphics card then you can do the following.
- Right-click on the desktop blank screen > Click on NVIDIA Control Panel.
- Click on 3D settings > Select Manage 3D settings in the left pane.
- Select the Program Settings tab > Choose Arma 3 from the drop-down list.
- Now, select a High-performance NVIDIA processor.
- Save changes and reboot the PC to apply changes.
AMD graphics card users can do the following.
- Right-click on the Desktop blank screen > Select AMD Radeon Settings from the context menu.
- Now, click on System > Select Switchable Graphics.
- Make sure to save changes and reboot the PC to apply changes.
2. Update GPU Drivers
Mostly an outdated or corrupted graphics card driver can trigger multiple issues with the games or system performance. It’s highly recommended to check the graphics driver update. To do so:
- Press the Windows + X keys to open the Quick Link Menu.
- Click on Device Manager from the list > Double-click on Display adapters.
- Right-click on the dedicated graphics card that you’re currently using.
- Click on Update driver > Choose Search automatically for drivers.
- If there is the latest update available, it’ll automatically download & install the latest version.
- Once done, restart the computer to apply changes immediately.
Alternatively, you can manually download the latest version of the graphics driver and install it on the PC via the official website. Make sure to download the graphics driver file respective to your graphics card model and manufacturer. Nvidia graphics card users can update the GeForce Experience app via the Nvidia official site and AMD graphics card users can visit the AMD website for the same.
3. Close Background Running Tasks
Unnecessary background running tasks or programs can eat up a lot of system resources like CPU or Memory usage literally reducing system performance. Hence, the startup crashing, lagging, and not loading issues appear quite often. Simply, close all the unnecessary background running tasks completely. To do this:
- Press Ctrl + Shift + Esc keys to open up the Task Manager.
- Now, click on the Processes tab > Click to select tasks that are unnecessarily running in the background and consuming enough system resources.
- Click on End Task to close it one by one.
- Once done, restart your system.
4. Change Power Plan
It’s also highly recommended to change the power plan on the computer because the Windows system basically uses the Balanced power plan by default. But it reduces performance which can be improved by changing the power plan. Keep in mind that the performance plan can consume higher power. To do so:
- Press the Windows + R keys to open the Run dialog box.
- Type Control Panel in the field and click on OK from the search result to open it.
- Now, search for Power Options (Power & battery) and open it.
- Click on Best Performance > Reboot your PC to save changes immediately.

- Now, make sure to select ‘Turn off VSync’.
- Then set each option under Advanced Settings to the low or medium.
6. Verify Game Files via Steam
Corrupted or missing game files may trigger some issues with the game launching or running smoothly. Make sure to verify the game files and repair them via the Steam client by following the steps below:
- Open the Steam client on the PC and log into the account > Head over to Library.
- Right-click on the Arma 3 game from the left pane.
- Click on Properties > Click on the Local Files tab.
- Then click on Verify Integrity of game files…
