Why is DLSS greyed out?

DLSS option is greyed out in the menu when hardware or drivers are not compatible.
Updating GPU drivers should make the DLSS option available, if you have supported hardware.

GPUs that support DLSS:

• Nvidia GeForce RTX 2000 series
• Nvidia GeForce RTX 3000 series
• Nvidia GeForce RTX 4000 series
