A new DLSS mode has come out to enable gaming at 8K. It is not intended to be used at low resolutions. In this video I try it out at low resolutions to see what happened.

Songs used:
'Don't Be So Serious'    • Low Roar  Don't Be So Serious  
'Holomorphic'    • Holomorphic  
'Reflect'    • David Randall  Reflect
