For the first time in years, Nvidia declined to introduce new GeForce graphics card models at CES. CEO Jensen Huang’s characteristically sprawling and under-rehearsed 90-minute keynote focused almost entirely on the company’s dominant AI business, relegating the company’s gaming-related announcements to a separate video posted later in the evening.
Instead, the company focused on software improvements for its existing hardware. The biggest announcement in this vein is DLSS 4.5, which adds a handful of new features to Nvidia’s basket of upscaling and frame generation technologies.
DLSS upscaling is being improved by a new “second-generation transformer model” that Nvidia says has been “trained on an expanded data set” to improve its predictions when generating new pixels. According to Nvidia’s Bryan Catanzaro, this is particularly beneficial for image quality in the Performance and Ultra Performance modes, where the upscaler has to do more guessing because it’s working from a lower-resolution source image.
DLSS Multi-Frame Generation is also improving, increasing the number of AI-generated frames per rendered frame from three to five. This new 6x mode for DLSS MFG is being paired with something called Dynamic Multi-Frame Generation, where the number of AI-generated frames can dynamically change, increasing generated frames during “demanding scenes,” and decreasing the number of generated frames during simpler scenes “so it only computes what’s needed.”
The standard caveats for Multi-Frame Generation still apply: It still needs an RTX 50-series GPU (the 40-series can still only generate one frame for every rendered frame, and older cards can’t generate extra frames at all), and the game still needs to be running at a reasonably high base frame rate to minimize lag and weird rendering artifacts. It remains a useful tool for making fast-running games run faster, but it won’t help make an unplayable frame rate into a playable one.
