    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.

        I really hope they do, but the market for gaming cards is looking mighty bleak right about now. 5090 is up over 80% since November last I checked and my 5080 is up 50%. NVIDIA removing all mentions of gaming in their financials doesn’t bode well either, and from a fiduciary standpoint it would be negligent to sacrifice any capacity for higher-margin AI chips to make gaming cards.

        Again, I hope I’m wrong and we see new cards summer/autumn 2027, but I would not bet my savings on it.

          It does OK on most of the 5 series cards, but you can only do 4k on the 5090 basically. And there are lots and lots of knobs to tune and experiment with.

          In some cases, it seems that lowering resolution and graphics actually produces better DLSS5 output (but it varies)

          It's really good at making older gen games look remade/remastered.
