FPS Fix!!
Go to C:\ProgramFiles(x86)\Steam\steamapps\common\No Man’s Sky\Binaries\SETTINGS
Then find the file “TKGRAPHICSSETTINGS.MXML” and open it.
You will then find the “GSync” option. It’s “true” by default, change it to “false”.
Then in game change the FPS option to MAX and APPLY it. VSYNC OFF.
