We’re testing out an up-and-coming feature in GOG Galaxy: Achievement Notifications that will be part of the game overlay in the future, and The Witcher 3: Wild Hunt is our playground!
Starting today, you too can experience that satisfying feeling of scoring a new achievement in GOG Galaxy, but beware – it’s a Beta feature that’s still being tested. On you.
In order to try it out yourself, you’ll first have to subscribe to the alternative update channel for The Witcher 3: Wild Hunt and download the most recent beta patch. To do this, navigate to your game’s GOG Galaxy page (simply click on the game in your sidebar), use the MORE tooltip to select CONFIGURE, and toggle the BETA CHANNELS setting to ON.
You’ll now be able to use the new CHANNEL dropdown to select the beta update channel for The Witcher 3: Wild Hunt – and enjoy the new Achievement Notifications. If you want to turn them off again, you can use the Rollback function to restore your game to the previous version.
