AltTabSky v1.0.0

AltTabSky lets you alt-tab out of No Man's Sky without the game pausing. It never injects into or modifies NMS.exe, so it works on every version of the game.

Use

1. Run AltTabSky.exe (it sits in the system tray, no window).
2. Launch No Man's Sky in Borderless or Windowed mode.
3. Alt-tab freely; the game keeps running.

Right-click the tray icon to toggle Active, enable Run at Windows startup, or Quit.

Use Borderless/Windowed. Exclusive fullscreen is minimized by the GPU driver on alt-tab, which nothing can prevent.

Requires: Windows, .NET Framework 4.7.2 (preinstalled on Windows 10/11).
