a


Building upon the major advancements introduced with NVIDIA DLSS 4.5, including a 2nd generation Super Resolution transformer model, Dynamic Multi Frame Generation, 6X Multi Frame Generation, and an enhanced Frame Generation model, we’re excited to announce DLSS 4.5 Ray Reconstruction, which features a new 2nd generation transformer model to deliver superior image quality in ray-traced and path-traced games.


The suite of DLSS 4.5 technologies offers GeForce RTX gamers the ultimate experience:

NVIDIA DLSS 4.5 Ray Reconstruction: Superior Ray-Traced Image Quality For All GeForce RTX Gamers - Coming This August​

DLSS Ray Reconstruction is a neural rendering technique for all GeForce RTX GPUs that improves image quality for ray-traced and path-traced scenes. Replacing traditional hand-tuned denoisers, it uses an NVIDIA supercomputer-trained AI network to generate higher-quality pixels in the noisy parts of a ray traced frame where rays were not sampled. The model unifies denoising and Super Resolution into a single model, intelligently analyzing temporal and spatial engine data to reconstruct sharper, more stable, and higher-fidelity high-resolution images.



DLSS 4.5 Ray Reconstruction is coming this August, introducing several major improvements:

• Efficient Denoiser: The new model delivers 35% more compute capability, and processes 20% more parameters, while maintaining similar performance to the previous model.
• Enhanced Super Resolution: Building upon the advances from DLSS 4.5 Super Resolution, the model has deeper spatial awareness across every scene, and more intelligently uses game engine pixel sampling and motion data. The result is improved lighting accuracy, better temporal stability and clearer motion in ray-traced and path-traced content.
• Expanded Training Dataset: Trained on a larger dataset, the new model is even better at image reconstruction. This intelligence gives the model even better awareness to pick the most accurate engine data to reconstruct scenes closer to ground truth.
• Finer Developer Control: The new model provides developers with finer control for temporal accumulation, providing precise tuning of model response for even better image quality.

These improvements are visible across a variety of games. In Indiana Jones and the Great Circle™, the new model delivers cleaner particle effects with virtually no snow ghosting.


In PRAGMATA™, lighting responsiveness from laser effects is significantly improved, along with reduced residual artifacts after the laser is disabled.


In Alan Wake 2, the CRT television scene preserves the fine individual lines of static white noise with greater clarity and stability.


When released, DLSS 4.5 Ray Reconstruction will be available for all GeForce RTX gamers via the NVIDIA app. At the time of writing, DLSS 4.5 Ray Reconstruction can enhance 27 games:


DLSS 4.5 Ray Reconstruction will be available for all GeForce RTX GPUs in August.

NVIDIA DLSS 4.5 Ray Reconstruction Coming To Blender​

Creative applications use hand-tuned denoisers for ray-traced content in different scenes, but they slow viewport interactivity to a wait and see approach, usually crippling iterative decision making. DLSS Ray Reconstruction maintains interactive viewport experiences while giving artists the final look in real-time, keeping their creativity unlocked.

Blender Cycles is integrating DLSS 4.5 Ray Reconstruction as a new denoiser, building upon the success of a prior OptiX integration. For 3D artists that need to interact in a scene while seeing near-final render quality, DLSS 4.5 Ray Reconstruction transforms the lighting and look-development workflow. The update will be released with Blender 5.3 this Fall.

Over 1000 RTX Games & Apps Now Available!​

On August 20th, 2018, NVIDIA founder and CEO Jensen Huang unveiled the GeForce RTX 2080, the world’s first RTX graphics card, capable of rendering movie-quality effects in real-time games. RTX cards introduced dedicated hardware and software designed to facilitate the next evolution of gaming graphics, and to this day GeForce RTX GPUs deliver the definitive RTX experience.

RTX encompasses an ecosystem of technologies that make high-performance, high fidelity gaming a reality. Ray Tracing, powered by dedicated RT Cores, brings immersive and realistic lighting and reflections to games. NVIDIA DLSS, made possible by Tensor Cores, enables industry-leading AI graphics acceleration, capable of delivering massive performance and enhanced image quality.

RTX is also integrated in the world’s leading creative applications, accelerating workflows by orders of magnitude, powering exciting AI tools and enhancements, and enabling real-time ray-traced previews in apps that could previously take hours to render.

Now, we’re over 1000 RTX games and apps, thanks to the ever-increasing adoption of DLSS, ray tracing, and RTX-accelerated AI.

We’re continually evolving and enhancing RTX technologies, and continue to deliver them to GeForce RTX gamers, nearly 8 years later.
