The First Descendant is the latest multiplayer title from NEXON that makes good use of Unreal Engine 5. There are plenty of settings to tweak in-game, but a few notable omissions as well. Similar to a few recent Unreal Engine 5 titles, the game has a distinct lack of downsampling options despite upscaling technologies available. If you want to enable DSR or VSR in The First Descendant externally, here is how you can do that.
Enable DSR in The First Descendant
To enable DSR or VSR support in The First Descendant, you can either manually set the resolution of your desktop to your target super resolution, or automate the process using AutoActions.
