If you're experiencing graphical issues, following are some troubleshooting tips that may help! (Please note, if you have mods installed, we'd recommend first uninstalling them to see if this helps fix any outstanding issues).
1: Please ensure that you have the latest drivers installed for your Graphics Card, this also goes for those that use onboard Graphics such as Intel. For Nvidia cards you will find drivers http://www.nvidia.co.uk/Download/index.aspx?lang=en-uk For Radeon cards you will find drivers http://support.amd.com/en-us/download For Intel on board graphics you will find drivers http://www.intel.com/content/www/us/en/support.html If you are unsure what drivers to download we recommend you use the "Automatically Find Drivers" option where possible. If there are any known issues associated with your drivers, you can find them on the *No Man's Sky Support Portal*.
2: If you are already running the latest drivers, we recommend you revert to a previous version of your driver to further ensure the issue is not driver related. For Nvidia cards you will find drivers http://www.nvidia.co.uk/Download/index.aspx?lang=en-uk For Radeon cards you will find drivers http://support.amd.com/en-us/download For Intel on board graphics you will find drivers http://www.intel.com/content/www/us/en/support.html
3: Ensure you have no mods installed, as these can very likely cause visual issues with the game! If you have any mods installed, please uninstall them, we then recommend you verify the integrity of your installation files!
4: Try deleting your Shader Cache.
5: If this does not work then please uninstall and re-install the game and delete any associated files. Once this is done, please re-install No Man's Sky through your game client and attempt to re-run the game.
