Introduction: Alt-Tab Agony Amidst Gaming Glory
The beauty of PC gaming lies in multitasking capabilities, with the Alt-Tab shortcut acting as a gateway between your game and other desktop tasks. However, when this quick switch results in a frozen screen, gaming joy quickly turns into tech-induced turmoil. This is especially true when you’re running Windows 11 as a lot of people have reported playing games like VALORANT and their system crashing when pressing ALT-TAB. So we will start with Windows 11 related tips.
Windows 11 Specific Tips
This issue is very common on Windows 11 based systems so try these in order (do each step then advance to the next step after testing):
