Pre-installation is a function in Genshin Impact that allows players to download some of the files and resources of an upcoming version in advance, which can reduce the time that the game spends updating resources on the first time you enter a new version. The pre-installation function is available on both PC and mobile platforms, and it is recommended that players complete any challenges they wish to finish first before beginning the pre-installation process. Travelers on mobile platforms will be unable to play the game while pre-installing game resources, while Travelers on PC can still play the game while pre-installing game resources. The pre-installation function will take up a certain amount of your networks bandwidth, so its best to make sure you have a good network connection before beginning pre-installation. After pre-installation is complete, players can update the game and experience new version content faster.

The pre-installation resource package size on PC ranges from 32 – 34.2GB, and players will need about 64 – 68.4GB of space to unzip the files. On mobile devices, players can access the pre-installation option through the game’s settings and click on “Resources” and then select “Pre-Install Now” . The file size for version 3.7 on mobile devices ranges from 2.5 GB to 4.5 GB, so players should ensure that their device has enough available space to accommodate the download.

In summary, pre-installation is a function in Genshin Impact that allows players to download some of the files and resources of an upcoming version in advance, which can reduce the time that the game spends updating resources on the first time you enter a new version. The pre-installation function is available on both PC and mobile platforms, and players should ensure that they have enough available space to accommodate the download.
