Nvidia has begun rolling out a beta feature that automatically compiles game shaders while a PC is idle. It won't eliminate shader compilation the first time a game runs, but Ars Technica reports it could help reduce those repeated wait times. From the report: Nvidia's new Auto Shader Compilation system promises to "reduc[e] the frequency of game runtime compilation after driver updates" for users running Nvidia's GeForce Game Ready Driver 595.97 WHQL or later. When the feature is active and your machine is idle, the app will automatically start rebuilding DirectX drivers for your games so they're all set to roll the next time they launch. While the feature defaults to being turned off when the Nvidia App is first downloaded, users can activate it by going to the Graphics Tab > Global Settings > Shader Cache. There, they can set aside disk space for precompiled shaders and decide how many system resources the compilation process should use. App users can also manually force shader recompilation through the app rather than waiting for the machine to go idle. Unfortunately, Nvidia warns that users will still have to generate shaders in-game after downloading a title for the first time. The Auto Shader Compiler system only generates the new shaders needed after subsequent driver updates following that first run of a new title.

Nvidia CEO Jensen Huang says he understands the concerns about "AI slop" with DLSS 5 but insists the feature preserves a game's underlying geometry and artistic intent. "I think their perspective makes sense, " said Huang during a recent appearance on the Lex Fridman podcast. "And I could see where they're coming from because I don't love AI slop myself. You know, all of the AI-generated content increasingly looks similar, and they're all beautiful... so I'm empathic toward what they're thinking. That's just not what DLSS 5 is trying to do." Tom's Hardware reports: Although Huang is striking a more conciliatory tone, much of his response is similar to what we heard at GTC [where Huang said gamers were "completely wrong."] The artist determines the geometry, we are completely truthful to the geometry... so every single frame, it enhances, but it doesn't change anything." There was some confusion about how DLSS 5 worked when it was first announced, and although the inner workings of it still aren't clear on a technical level, Huang has said that it isn't a general-purpose generative AI model. He describes it as "content-controlled generative AI." On the other end of the spectrum, Huang also said that it isn't a post-processing filter. The technical details of DLSS 5 live somewhere between that space, and we likely won't know them until later this year when the feature is set to release. "The question about enhancing, DLSS 5... in the future, you could even prompt it. You know, I want it to be a toon shader. I want it to look like this, kind of. You could even give it an example and it would generate in the style of that, all consistent with the artistry, the style, the intent of the artist," Huang continued. "All of that is done for the artist so they can create something that is more beautiful but still in the style that they want." Although the talking points about DLSS 5 remain unchanged, it seems that Huang has at least heard the criticism. "I think that they got the impression that the games are going to come out the way the games are... and then we're going to post-process it. That's not what DLSS is intended to do." Huang also made assertions that DLSS is "integrated" with the artist, and suggested that it would put the power of generative AI in the hands of artists working in game development [...]. Although DLSS 5 looks like it's doing a lot, Huang said that it's just another tool, not an essential feature. "The gamers might also appreciate that, in the last couple of years, we introduced skin shaders to game developers, and many of those games have skin shaders that include sub-surface scattering that makes skin look more skin-like... [DLSS 5] is just one more tool. They can decide what to use," Huang ended the conversation about DLSS 5. Immediately after, without missing a beat, he said 1993's Doom was the most influential video game ever made.

Kyle Orland writes via Ars Technica: Since deep-learning super-sampling (DLSS) launched on 2018's RTX 2080 cards, gamers have been generally bullish on the technology as a way to effectively use machine-learning upscaling techniques to increase resolutions or juice frame rates in games. With yesterday's tease of the upcoming DLSS 5, though, Nvidia has crossed a line from mere upscaling into complete lighting and texture overhauls influenced by "generative AI." The result is a bland, uncanny gloss that has received an instant and overwhelmingly negative reaction from large swaths of gamers and the industry at large. While previous DLSS releases rendered upscaled frames or created entirely new ones to smooth out gaps, Nvidia calls DLSS 5 -- which it plans to launch in Autumn -- "a real-time neural rendering model" that can "deliver a new level of photoreal computer graphics previously only achieved in Hollywood visual effects." Nvidia CEO Jensen Huang said explicitly that the technology melds "generative AI" with "handcrafted rendering" for "a dramatic leap in visual realism while preserving the control artists need for creative expression." Unlike existing generative video models, which Nvidia notes are "difficult to precisely control and often lack predictability," DLSS 5 uses a game's internal color and motion vectors "to infuse the scene with photoreal lighting and materials that are anchored to source 3D content and consistent from frame to frame." That underlying game data helps the system "understand complex scene semantics such as characters, hair, fabric and translucent skin, along with environmental lighting conditions like front-lit, back-lit or overcast," the company says. Nvidia's announcement video and detailed Digital Foundry breakdown can be found at their respective links. "Reactions have compared the effect to air-brushed pornography, 'yassified, looks-maxed freaks,' or those uncanny, unavoidable Evony ads," writes Orland. "Others have noted how DLSS 5 seems to mangle the intended art direction by dampening shadows in favor of a homogenized look." Thomas Was Alone developer Mike Bithell said the technology seems designed "for when you absolutely, positively, don't want any art direction in your gaming experience." Gunfire Games Senior Concept Artist Jeff Talbot added that "in every shot the art direction was taken away for the senseless addition of 'details.' Each DLSS 5 shot looked worse and had less character than the original. This is just a garbage AI Filter." DLSS 5's "AI dogshit is actually depressing," said New Blood Interactive founder and CEO Dave Oshry, adding that future generations "won't even know this looks 'bad' or 'wrong' because to them it'll be normal."
