Nvidia is rolling out DLSS 4.5 to every GeForce RTX GPU from day one, extending support across the RTX 20, RTX 30, RTX 40, and the latest RTX 50 series Blackwell graphics cards. The company positions DLSS 4.5 as one of its most notable CES 2026 keynote announcements, and it is designed to be enabled easily through the Nvidia app. Users can open the Graphics tab, select the option labeled DLSS Override – Model Preset, and apply this configuration as a global setting or individually for specific programs to control how DLSS behaves per title.
Within the Nvidia app, choosing the Recommended option configures Preset M to DLSS Performance mode, Preset L to DLSS Ultra Performance mode, and Preset K to the other available modes, giving players a structured way to trade off image quality against frame rate. Nvidia states that this setup works with more than 400 titles that support DLSS Super Resolution, and over 250 titles that work with the multi-frame generation of DLSS 4. By aligning presets with existing DLSS modes, the company is trying to make the new capabilities accessible without forcing users to learn an entirely new configuration model.
DLSS 4.5 builds directly on the architectural change introduced with regular DLSS 4, where Nvidia shifted from convolutional neural network based Artificial Intelligence models to a Transformer based architecture to significantly improve image quality. The new release updates the algorithm with a more advanced Transformer model trained on a much larger dataset, and this second-generation Transformer was developed with five times the computational investment of the first DLSS 4 Transformer upscaler and utilizes the FP8 data format, allowing for more processing with minimal precision loss. Nvidia says the algorithm is more context aware and uses input data for upscaling more intelligently, which results in more detailed and precise video output. For GeForce RTX 50 series GPUs, Nvidia dedicated a dynamic multi-frame generation with 6x increase in rendered frames as an exclusive feature, while older RTX series are left on 2x, creating a performance tier that favors the latest hardware while still upgrading previous generations.
