Nvidia is pushing its AI graphics stack in two directions at once this week: deeper into how games are rendered, and wider in terms of where they can be played.
The technical centerpiece is DLSS 4.5. According to Wccftech, the release brings a second-generation Transformer model to Ray Reconstruction, the component that cleans up ray-traced and path-traced lighting, with the aim of improving image quality on GeForce RTX GPUs. TechPowerUp published a review of the same feature under the header "Transformer Improved," signaling an iteration on the existing model rather than a ground-up replacement.
A hands-on test published via MSN frames the bigger shift plainly: DLSS has "steadily moved beyond its original role as an AI upscaler," and with DLSS 4.5 the technology "now increasingly sits between the game engine and the final image that reaches the display." That test also examines dynamic multi frame generation alongside ray reconstruction.
On the distribution side, The Verge reports that Nvidia's GeForce Now cloud gaming service will officially support Valve's Steam Controller and Steam Machine starting later this year — meaning you'll be able to use Valve's new gamepad with the GeForce Now app on a Steam Deck or Steam Machine. TechPowerUp adds that GeForce Now is also gaining DLSS 4.5 settings and new games alongside the Steam Machine support.
Separately, TechPowerUp reports that EA, Embark, and Ubisoft are bringing blockbuster titles to Nvidia's RTX Spark.
Why it matters: Nvidia is quietly moving from selling faster silicon to owning the layer where the picture actually gets made — and by putting that layer on Valve's hardware through the cloud, it reaches players who never bought an RTX card at all.
