NVIDIA has announced DLSS 4.5 Ray Reconstruction, a new AI-powered update to its ray tracing technology. It launches in August and works on all GeForce RTX graphics cards.
What Is DLSS 4.5 Ray Reconstruction?
The update replaces the hand-tuned denoisers that RTX graphics currently use for ray-traced rendering. Instead, a second-generation transformer AI model takes over. It analyzes spatial and temporal game data to reconstruct missing visual detail. The result is sharper images, more stable lighting, and fewer ghosting artifacts in supported games.
This is not a standalone feature. DLSS 4.5 Ray Reconstruction merges Super Resolution and Ray Reconstruction into one unified model. That means the AI processes both upscaling and denoising together, rather than treating them as separate tasks.
What Changes Under the Hood
The new denoiser delivers 35% more compute capability while processing 20% more parameters. NVIDIA says it also benefits from enhanced scene awareness, better motion clarity, improved temporal stability, and a larger training dataset. Developers get more control over temporal accumulation settings too, which lets them fine-tune image quality for their specific games.
The most visible improvement is in fast-moving effects. Particle systems, weather, and laser lighting have historically caused ghosting and noise in ray-traced scenes. Scenes with this kind of animation have reportedly shown cleaner motion handling and reduced ghosting.
Which Games Get Support at Launch
At launch, DLSS 4.5 Ray Reconstruction will be compatible with 27 games, including Cyberpunk 2077, Alan Wake 2, Indiana Jones and the Great Circle, DOOM: The Dark Ages, Star Wars Outlaws, Hogwarts Legacy, F1 25, Resident Evil Requiem, PRAGMATA, and Call of Duty: Black Ops 7.
Beyond the launch list, more titles are arriving with DLSS 4.5 support throughout the year. Phantom Blade Zero is scheduled to launch this fall with DLSS 4.5 Super Resolution and ray tracing features, while Marvel Rivals will receive native DLSS 4.5 Super Resolution and Dynamic Multi Frame Generation support in an update arriving June 12. NARAKA: BLADEPOINT gets the upgrade on June 5.
DLSS 4.5 Ray Reconstruction Comes to Blender Too
Gaming is not the only target. NVIDIA confirmed that DLSS 4.5 Ray Reconstruction is coming to Blender as well. The feature will be integrated into Blender Cycles as a new denoising option when Blender 5.3 launches later this year. NVIDIA says the technology will allow artists to view near-final rendering quality in real time while maintaining responsive viewport performance.
NVIDIA revealed that more than 1,000 RTX-enabled games and applications are now available, driven by growing adoption of DLSS, ray tracing, and AI-accelerated technologies. The company first introduced RTX graphics cards in 2018 with the GeForce RTX 2080.
How to Get the Update
The update will be distributed through the NVIDIA App when it becomes available in August. No separate downloads or manual installs are required for supported games.
