  • Run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth in Command Prompt as admin.

  • Check Event Viewer for errors.



🎮 1. Understanding GPU Switching

Your laptop likely has:

  • Intel Iris Xe (integrated) – power-efficient, used for light tasks.

  • Discrete GPU (NVIDIA or AMD) – powerful, used for demanding apps like CAD, Vectorworks, games, etc.

🧠 The system can dynamically switch based on the workload, but sometimes this needs manual tuning for the best result.


⚙️ 2. Set Preferred GPU for Specific Apps (Best Practice)

Windows 10/11 Settings

  1. Go to: Settings > System > Display > Graphics

  2. Under “Custom options for apps”, click Browse
