    Almost 8ms on 1080p resolution seems extremely expensive, does the original also eat into the rendering budget as much?

      Yes, see the numbers below. In most games, it's basically unusable if you want to play on 60 FPS or above unless you have a 5090.

      The current implementation is more of a tech demo than a practical way to play games (+ officially it's available in 1 game). It's _fast enough_ to make some impressive YouTube videos but you most likely won't want to play anything with it yet.

      Nvidia has stated that they're still working on improving the performance. No doubt future hardware generations will also include further hardware optimisations.

      The potential for this kind of technology is pretty awesome, especially given that people have also found ways to add this to emulators.

        Modders have added the ability to use the upscaler after DLSS 5, personally I don't know how sound this method is but the quality is pretty good, and allows to play games with DLSS 5 at 4k 60FPS with something that is not a 5090.
