Did you notice strange issues with your games? If so, you are probably thinking of ways how to verify integrity of game files. This is an excellent path since corrupted game files are among the most frequent causes of crashes, launching issues, and poor game performance.

Gamers have struggled with these problems since the early age of computer games, so major game distribution platforms created a system to solve it. The old-fashioned method was to uninstall the game, delete game files and reinstall it. Nowadays you don’t have to do it!

There are no more excuses for struggling with annoying game issues when the verification of game files is available in only a few clicks. Some patience is still needed since some games are over 100GB, but trust us when we say that verifying the integrity of game files is much faster than reinstalling the whole game.

What does verifying file integrity mean?

Verifying file integrity is comparing the version of the file on your PC with the original version on the game distribution platform. If the platform detects any differences, it will flag the file as corrupted and immediately fix it. Instead of reinstalling the complete game, you will restore corrupted files and be ready.
