  "textContent": "Nvidia is filling in the last missing piece of its DLSS 4.5 lineup. After rolling out a new Super Resolution model and 6X Multi Frame Generation, the company has now revealed DLSS 4.5 Ray Reconstruction, an updated AI denoiser for ray-traced and path-traced games. It is built on a second-generation transformer model and is aimed at producing cleaner, more stable lighting without forcing you to give up much performance.\n\n🗓️\n\nQuick answer: DLSS 4.5 Ray Reconstruction launches in August for every GeForce RTX GPU (RTX 20, 30, 40, and 50 series) through the Nvidia app, with 27 supported games at launch.\n\n* * *\n\n## What DLSS 4.5 Ray Reconstruction does\n\nRay Reconstruction is a neural rendering technique that replaces the hand-tuned denoisers games normally use to clean up noisy ray-traced lighting, reflections, and shadows. Instead of separate filters tuned by developers, Nvidia uses an AI network trained on its supercomputers to fill in the parts of a frame where rays were not sampled.\n\nThe model combines denoising and Super Resolution into a single network. It reads temporal and spatial data coming out of the game engine, then rebuilds a sharper, higher-resolution image that stays stable as you move through a scene. The underlying way it works has not changed for 4.5, but the model itself is now larger and smarter about how it uses that engine data.\n\nPragmata running with DLSS 4 Ray Reconstruction.The same Pragmata scene with DLSS 4.5 Ray Reconstruction.\n\n* * *\n\n## What's new in the second-generation model\n\nThe headline change is a heavier transformer model that runs without a meaningful drop in frame rate. Nvidia says it delivers 35% more compute capability and processes 20% more parameters while keeping performance similar to the previous version, because the network is more efficient. The practical result is sharper images with fewer artifacts in demanding ray-traced and path-traced scenes.\n\nImprovement| What it changes\n---|---\nEfficient denoiser| 35% more compute capability and 20% more parameters, at similar performance to the old model\nEnhanced Super Resolution| Deeper spatial awareness and smarter use of engine pixel sampling and motion data for better lighting accuracy and motion clarity\nExpanded training dataset| Trained on a larger dataset to pick more accurate engine data and reconstruct closer to ground truth\nFiner developer control| More precise tuning of temporal accumulation for better image quality\n\nNvidia showed off the difference with a few examples. In _Indiana Jones and the Great Circle_ , the model produces cleaner particle effects with almost no snow ghosting. In _PRAGMATA_ , laser lighting reacts faster and leftover artifacts vanish once the laser is switched off. And in _Alan Wake 2_ , the CRT television static keeps its fine individual lines with more clarity and stability instead of smearing away.\n\nAlan Wake 2 is one of the games getting the updated Ray Reconstruction model.DLSS 4 Ray Reconstruction handling the CRT static scene.The same scene with DLSS 4.5 Ray Reconstruction, keeping the static cleaner.\n\n* * *\n\n## Which RTX GPUs are supported\n\nThis is the part most people will care about. DLSS 4.5 Ray Reconstruction works on every GeForce RTX card, going all the way back to the RTX 20 series. That means RTX 20, RTX 30, RTX 40, and RTX 50 owners all get access to the new model. There is no Blackwell-only lock here, unlike 6X Multi Frame Generation, which stays exclusive to the RTX 50 series.\n\n* * *\n\n## DLSS 4.5 Ray Reconstruction supported games at launch\n\nThe feature arrives with 27 games able to use the new model. The lineup includes major path-traced titles alongside multiplayer and creative-looking releases.\n\nGames| Games| Games\n---|---|---\nAlan Wake 2| Enlisted| NTE (Neverness to Everness)\nAvatar: Frontiers of Pandora| EVERSPACE 2| Portal with RTX\nBackrooms: Escape Together| F1 25| PRAGMATA\nCall of Duty: Black Ops 7| FBC: Firebreak| Resident Evil Requiem\nCrimson Desert| Half-Life 2 RTX| Samson\nCyberpunk 2077| Hogwarts Legacy| Star Wars Outlaws\nDeath Relives| Incursion Red River| Subliminal\nDirective 8020| Indiana Jones and the Great Circle| Sword of Justice\nDOOM: The Dark Ages| NARAKA: BLADEPOINT| The First Descendant\n\nThe list is expected to grow over time as more titles adopt the model. Phantom Blade Zero, the action RPG from S-GAME, is also set to launch this fall with DLSS 4.5 and ray-traced reflections, shadows, and caustics.\n\n* * *\n\n## How to get DLSS 4.5 Ray Reconstruction\n\nWhen it goes live in August, the update is delivered through the Nvidia app, so you do not need to wait on individual game patches to swap in the new model. You can install the app and then use it to apply the latest DLSS model to supported titles.\n\nDownload the Nvidia app\n\nYou will know the new model is active when DLSS 4.5 Ray Reconstruction appears as a selectable option in the app for a supported game. Nvidia confirms the visual gains apply across all RTX generations, although older GPUs without FP8 acceleration will not see the same level of performance headroom as Ada and Blackwell cards.\n\n* * *\n\n## DLSS 4.5 Ray Reconstruction in Blender Cycles\n\nThe technology is not limited to games. Blender Cycles is adding DLSS 4.5 Ray Reconstruction as a denoiser, building on an earlier OptiX integration. For 3D artists, the goal is an interactive viewport that shows near-final ray-traced lighting in real time, instead of the usual wait while a denoiser catches up. That integration is planned to arrive with Blender 5.3 this fall.\n\nNvidia is framing all of this around a milestone of more than 1,000 RTX games and apps, nearly eight years after the original RTX 2080 launched in 2018. Ray Reconstruction was the one DLSS 4.5 component still missing, and with an August release across the full RTX range, the suite is now complete for anyone running a GeForce RTX card.",
