What does DLSS do, and what's up with DLSS 5?

  Skipping the what, it was covered.

  Why? Gamers screech about everything. They have an absurdity vocal minority who are just some of the worst people to deal with on the planet. Nothing will make them happy. They’ll screech at a $70 game that gave them 100 hours of play time on principle.

  They screeched about dlss1 and they’ll continue to do so. They’ll all be using it and it’ll be tweaked to look even better in a few years.

  DLSS is machine learning model trained by Nvidia to invent information to rendered game frames. In general there are two ways:

  • You have two frames of game, model makes up third frame between those two frames, to make game run smoother. This has down side that input lag (you press button and it happens on screen) gets longer. But in increases your FPS (frames per second), which looks smoother.
  • model makes up extra detail to the game frame. Previous versions have mainly being AI upscaling. Game renders in smaller resolution (less pixels), and then it is made larger, and model smooths and makes up details that originally wasn’t there.

  Both of these have same downside, they can cause inconsistency between frames, and have flickering etc.

  This is what DLSS 5 now takes to much more heavier “AI filter” level, because it is not anymore upscaling, but it now can add much more detail that originally wasn’t there. But because the model doesn’t have memory, it must always cause issue that the output will always be bit different. Curious to see how they have overcome that.

  DLSS uses AI tricks to improve framerate.

  Previous versions used AI upscaling and frame generation.

  This version now uses AI filters. It changes lighting and texture effects to make the image “better”, instead of just making the image faster.
  It’s actively manipulating creative decisions about the style of a game. Which naturally upsets many developers and players alike.

  Nvidia’s software bits for upscaling (game plays with lower resolution, GPU does funny things to make it look higher resolution), frame insertion (in a nutshell, creating fake frames in between real frames to make gameplay look smoother), and similar. Many of the features require game support though, so many games are unable to utilise the more advanced features. These can also result in a degradation in quality and increased latency.

  DLSS 4 introduced multi frame gen, where up to three fake frames were made for every one. It doesn’t magically make you have 4x the performance (so no, the 5070 is not the performance of the 4090), but it’s still pretty neat tech.

  DLSS 5 is being criticised as it’s “enhancing” video game graphics to look like AI-generated images that look more “cinematic” and “photorealistic”. To quote an IGN article, “I think it looks shit.” (ign.com/…/nvidias-dlss-5-is-a-slap-in-the-face-to…)

  In other words, it’s removing the human element of game graphics and nobody likes it.

  It makes games run smoother and look cleaner.

  5 replaces assets in the game with AI bullshit.

    It’s more like running an ai instagram filter over the game, than replacement. Still unnecassary though.

    It makes games run worse and look horrible because devs now target dlss performance mode for 60fps on medium hardware. The game is rendered at 720p and blurred to death until you can’t notice the half rendered frame and pixelated effects that depend on it (and TAA).

    It’s also a marketing ploy to lie to consumers, saying their cards get 3x the performance of the previous Gen, by generating fake frames in between real ones. Displaying garbage but because the benchmark say 100+fps, it must be better right? Even though there are more presentation errors, latency is through the roof and the result is insane.

    DLSS 5 continues the trend of lies by simply putting a yassification filter on top, lies to the dev, and lies to the consumers.

      That’s hella weird. 720p only upscales nicely on multiples, so 1440p or 2880p, but last I checked only about 15% of Steam users have QHD monitors. They should’ve gone 960*540 at the very least.

      Of course, they shouldn’t half-ass their quality regardless. Frame gen is fine I guess, but not rendering at full res and using AI to distort the original is a huge issue.
