What benefits do flatscreen users see to DLSS4?

With a 4090, I have a fluid experience on a 4k flatscreen. What are the experiences of people here with a flat screen and DLSS4?

I am running triple 1440p on a 4090.  Installed new drivers last week and used nvidia Profile Inspector to force DLSS4 usage by DCS. 

The tangible improvement I’ve seen is the ability to use DLAA instead of MSAA 4x with no or barely perceptible ghosting. Previously, the ghosting was pretty bad, offsetting the better antialiasing and fps offered by DLAA. 

DLAA looks amazing to me, even better than MSAA, and runs very smooth in comparison. 
 

DLSS upscaling is improved a lot…much reduced ghosting, but it is still noticeable. The boost in fps from DLAA (which is already a big jump in fps from MSAA) isn’t worth the ghosting.
