On there site they have said DLSS 4 is available day 0, so i assume on the 30th it will be available for all cards that can use it... you just need to have the Nvidia app to update games to DLSS 4Is DLSS 4 releasing on the same day as the 50 series cards? And will it be immediately available for older cards too?
I'm intrigued why they didn't show both the 4090 and 5090 using the latest dlss 4 when showing it off at ces.
