NTE black screen after Alt+Tab? How to fix

1) Switch to windowed or borderless windowed mode in game settings 2) Press Alt+Enter to toggle fullscreen 3) Press Ctrl+Shift+Esc to open Task Manager, then switch back to the game 4) Disable fullscreen optimization (right-click game exe → Properties → Compatibility) 5) Update GPU drivers. The most effective solution is using borderless windowed mode — slight performance trade-off but avoids the black screen issue.
