Fix Resident Evil 4 (2005) Freezing & Hangs

**Resident Evil 4 (2005)** is freezing or becoming unresponsive. This is a *widely reported issue* with likely solutions. Freezes differ from crashes — the game stops responding but doesn't close. This is often caused by GPU driver timeouts (TDR), deadlocked threads, or I/O bottlenecks. These steps should resolve it for most players: 1. Open the calendar view. 2. Click an existing event to open the editor. 3. Change the event title and click Save. 4. Increase the Windows TDR (Timeout Detection and Recovery) delay via registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers → TdrDelay (DWORD) → set to 10. 5. Disable fullscreen optimisations: right-click the game .exe → Properties → Compatibility → check 'Disable fullscreen optimisations'. 💡 *Quick tip:* Try Alt+Tab out and back in — this can break some freeze loops related to fullscreen rendering. 📎 Sources: GitHub Issues
