No Man’s Sky Not Using GPU, How to Fix?

Whenever the game doesn’t use the dedicated or external graphics card on your PC and starts using the integrated GPU, the chances are high that it starts experiencing some issues during launching or gameplay. Not only does the game stutter, but it also triggers graphical glitches, frame drops, crashes, etc. Now, if you’re also facing the same issue or somehow the game lags so much and keeps stuttering here & there, you should manually try fixing it out.

Here we’ve shared a couple of possible workarounds for you that should help a lot. So, without wasting any more time, let’s jump into it.

1. Use a Dedicated Graphics Card

Ensure that your computer system uses the dedicated or external graphics card to run the No Man’s Sky 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.

For Nvidia:

You can do the following if you’re using the Nvidia graphics card.

  • 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 No Man’s Sky from the drop-down list.
  • Now, select a High-performance NVIDIA processor.
  • Save changes and reboot the PC to apply changes.

For AMD:

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Mostly an outdated or corrupted graphics card driver can trigger multiple issues with the games or system performance.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:

Advertisements
  • 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.

Device Manager Update Display Adapter

  • Click on Update driver > Choose Search automatically for drivers.
  • If the latest update is 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 graphics driver version 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, reducing system performance. Hence, the startup crashing, lagging, and not loading issues often appear. Simply close all the unnecessary background running tasks completely. To do this:

Advertisements
  • 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. End Task Manager
  • 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 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.

5. Tweak In-Game Graphics Settings

You can also change the in-game graphics settings to check if the problem is still appearing or not.

  • Launch the Steam client and then open No Man’s Sky from Library.
  • Click on the gear icon inside the No Man’s Sky game to enter the Settings menu.
  • Now, make sure to select ‘Turn off VSync’.
  • Then set each option under Advanced Settings to the low or medium.

6. Disable Overclocking of the GPU

If, in case, you’re using MSI Afterburner or any other GPU overclocking software on your PC, then we recommend you to disable the overclocking option and uninstall the software to avoid GPU-related issues. Though the GPU overclocking function can help your system and hardware to run graphics-intensive games or programs much smoother, sometimes it may trigger multiple issues with the performance. So, you should try it out.

7. Delete ‘SGA’ Prefix Game Files

Sometimes some game files on the PC can also cause several issues with the game launching or using any specific feature whatsoever. Some reports are suggesting that No Man’s Sky game files having the SGA extension are somehow troubling the game files to run properly. Deleting all the SGA prefix files from the installed game folder is recommended to get rid of the GPU not working or not detecting issues. To do so:

  • Press the Windows + E key to open File Explorer.
  • Go to the Documents folder from the left pane > Open the Rockstar Games folder.
  • Open the No Man’s Sky folder > Go to the Settings folder.
  • Here you can see three files with the SGA prefix. Just delete the SGA files.
  • Once done, close File Explorer > Reboot the PC and try launching the No Man’s Sky game again.

8. Tweak Launch Options or Arguments

Well, command-line arguments are additional (forceful) command prompts to the specific game client/launcher to run a specific game using a specified feature. That means if the game or the client cannot run any specific feature/option, you can run that forcefully by commanding arguments. So, if the No Man’s Sky game cannot detect or use the dedicated GPU or throws out the ERR_GFX_STATE error, you can follow the steps.

For Steam:

  • Open your Steam client > Click on LIBRARY.
  • Right-click on No Man’s Sky from the left pane > Select Properties.
  • Now, click on SET LAUNCH OPTIONS.
  • Type -ignorepipelinecache in the field and select OK.
  • Once done, make sure to launch No Man’s Sky to check if the error is still bothering you or not.

For Epic Games Launcher:

  • Open your Epic Games Launcher > Click on Settings from the bottom-left side.
  • Scroll down to No Man’s Sky > Tick mark the Additional Command Line Arguments checkbox.
  • Type -ignorepipelinecache in the field and go back to the main menu.
  • Run the No Man’s Sky game to check for the issue again.

9. Verify and Repair Game Files

If, in case, your installed game files have some issues with the corruption or missing files, then the chances are high that you’ll encounter crashes, lags, stutters, GPU errors, graphical glitches, etc., on the PC. It’s always better to verify and repair the game files automatically from the game launcher, whatever you use. You can verify the files using the following steps below for your specific game launcher/client. To do so:

For Steam:

  • Open the Steam client on the PC and log into the account > Head over to Library.
  • Right-click on the No Man’s Sky game from the left pane.
  • Click on Properties > Click on the Local Files tab.
  • Then click on Verify Integrity of game files…
  • Now, wait for the process to complete and close the Steam client.
  • Finally, restart the PC to apply changes.

For Epic Games Launcher:

  • Open the Epic Games Launcher > Click on Library.
  • Click on the three-dots icon of No Man’s Sky.
  • Click on Verify, and it’ll start verifying the game files.
  • Wait for the process to complete and restart the launcher.

10. Reinstall No Man’s Sky

If none of the methods worked for you, try reinstalling the No Man’s Sky game on the PC to check if that helps you fix the lagging or FPS drop issue due to not using a dedicated GPU (graphics card).

  • Open the Steam client on your PC.
  • Go to Library > Right-click on No Man’s Sky.
  • Select Uninstall > Click on Delete to confirm.
  • Wait for the uninstallation process to complete > Exit the Steam client.
  • Now, open the File Explorer application > Copy-paste C:\Program Files (x86)\Steam\steamapps\common on the address bar and hit Enter to search for the location.
  • Go to the No Man’s Sky folder and simply Delete the folder completely.
  • Reboot the PC to apply changes > Open Steam Store and Reinstall the No Man’s Sky game again. [Obviously, this may take enough time, but you should try it out]
  • It should fix the lag or FPS drop issue completely.
