2. No bigotry or harassment, be civil

No bigotry, hardline stance. Try not to get too heated when entering into a discussion or debate.

We are here to talk and discuss about one of our passions, not fight or be exposed to hate. Posts or responses that are hateful will be deleted to keep the atmosphere good.

DLSS 5 comes with a massive 50-60% performance hit, so I hope you like lower frame rates with your dose of AI image enhancement (www.pcgamer.com)

The very bad news is, Nvidia says turning DLSS 5 on will currently reduce performance by 50-60%. And that's across the board—no matter the game.

If the materials rendering part were integrated into the rendering pipeline as a standard thing that could be called with an API, that could be pretty good. Just pass along some info about the material and let it render like any other basic shader. But because it's a post-processing shader that needs to analyze the entire image and work out materials on the fly to objects that have already been rendered, it murders the frame rate and can make mistakes on its guesses. There's something legitimately interesting burried in there, but this is the worst possible way to implement it.

Yeah, this sounds dumb as fuck. They're rushing and making the worst choices possible to push big marketing ideas.

Same as anything AI: if they slow down and make sure everything is done by the book, it could really be a useful tool, but they're too high on power to care about any of this.
