NVIDIA presented a series of updates to its gaming technologies, including version 4.5 of its Deep Learning Super Sampling (DLSS) image-upscaling technology, new features for its RTX Remix platform, and enhancements for G-Sync monitors during its CES presentation. The announcements also included new native clients for Linux and Fire TV, alongside updates to the NVIDIA App.
DLSS 4.5 Enhancements
DLSS 4.5 introduces significant advancements across two primary components: the 2nd Generation Super Resolution Transformer and new Multi-Frame Generation capabilities.
2nd Generation Super Resolution TransformerThis updated Super Resolution model is designed to provide enhanced visual clarity, improved temporal stability, reduced ghosting artifacts, and better anti-aliasing. It is available for all NVIDIA RTX GPUs through new drivers and an update to the NVIDIA App.
NVIDIA stated that this second-generation model utilizes five times the compute power of the original transformer model, having been trained on an expanded, high-fidelity dataset to improve image quality and reduce artifacting, particularly in DLSS Performance and Ultra Performance modes.
Testing observations, including a comparison video by MxBenchmarkPC, indicated image quality improvements in games such as Red Dead Redemption 2, where terrain and grass textures appeared sharper with DLSS 4.5. However, the new Super Resolution Transformer model also exhibited rendered inconsistencies with tree foliage, resulting in a less detailed appearance in these areas. In Cyberpunk 2077 with Path Tracing, the model addressed certain ground texture issues but introduced additional visual artifacts, such as oversharpening in other areas. A reported performance impact compared to previous Super Resolution models is minimized on RTX 50 and 40 series GPUs due to FP8 implementation in Blackwell and Ada architectures.
Multi-Frame GenerationDLSS 4.5 includes 6x Multi-Frame Generation (MFG) and Dynamic Multi-Frame Generation. This feature is designed to optimize frame rates, supporting up to 4K 240Hz performance, particularly in path-traced environments, and aims to contribute to smoother gameplay.
The multi-frame generation capability now extrapolates up to six frames from a single rendered frame, an increase from the previous four, by generating up to five additional frames. The system dynamically adjusts the render-to-generated ratio to the monitor's refresh rate, with the goal of maintaining consistent speed and latency. Dynamic Multi-Frame Generation is specifically designed for monitors with refresh rates exceeding 240Hz.
These Multi-Frame Generation options will be exclusive to NVIDIA RTX 50 series GPUs and are scheduled for release in spring 2026. The efficiency of these technologies has been noted in the context of demanding visuals for upcoming PC game releases.
RTX Remix Logic
NVIDIA introduced RTX Remix Logic, a feature enabling real-time environmental responses to in-game actions within the RTX Remix modding platform. This technology allows for dynamic changes such as adjustments to volumetric conditions, display of varying weather simulations with particle effects, and alterations to material properties. RTX Remix Logic can detect over 30 distinct common in-game events and adapt volumetrics, particles, material properties, and light properties accordingly.
G-Sync Enhancements
For G-Sync-capable monitors, a new potential feature, Ambient Adaptive Technology (AAT), was announced. AAT requires a monitor equipped with a light sensor and is designed to automatically adjust color temperature and brightness according to environmental conditions. Additionally, NVIDIA stated that G-Sync Pulsar monitors, initially launched in September 2024, are expected to become available soon. Pulsar technology aims to enhance clarity in fast-moving games displayed on high refresh-rate monitors.
NVIDIA App and Other Announcements
NVIDIA confirmed the availability of native clients for both Linux and Fire TV. The company also released an update for its NVIDIA App (version 11.0.6), which introduces DLSS 4.5 Super Resolution and integrates all remaining NVIDIA Surround settings from the legacy Control Panel, including bezel correction and hotkeys. This continues NVIDIA's initiative to consolidate its Control Panel and GeForce Experience into a unified application. The latest Game Ready driver is required to enable DLSS 4.5 functionality.
