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' https://youtu.be/IB1URcYIaOE
'Holomorphic' https://youtu.be/arnddZe9f4o
'Reflect' https://youtu.be/EVOy2u1QUfo
