When you open your start menu, sometimes there is lag. You can make your PC more snappy and crisp by making your common interactions more responsive.
Everytime you press the Win key a flyout menu appears with a subtle fade. Let's get rid of that start menu animation:
- Open your settings WIN + i
- Search for Show animations in Windows
- In your Display settings, toggle the option to Off
Normally, one would goto the Performance Options Visual Effects tab to Adjust the appearance and performance of Windows because that's makes sense but the start menu is not related.
