DLSS 4.5 Ray Reconstruction is out for every GeForce RTX GPU, and you turn it on through the Nvidia app. It swaps the older hand-tuned denoisers for a second-generation transformer model that cleans up noisy ray-traced and path-traced frames, giving sharper lighting, steadier motion, and less ghosting in supported games.
Quick answer: Open the Nvidia app, go to Settings > About and opt in to Early Access releases, then set Ray Reconstruction to “Recommended” or “Preset F” under DLSS Override – Model Presets for a supported game (or in Global Settings).
What you need before enabling it
Ray Reconstruction works on any GeForce RTX card, but the new model ships as an Early Access feature in the Nvidia app, with a full public release following in September. Confirm the items below before you start.
| Requirement | Detail |
|---|---|
| GPU | Any GeForce RTX GPU |
| Driver | GeForce Game Ready Driver 580.88 WHQL or newer |
| App | Nvidia app with the latest update installed |
| Access | Opt in to Early Access releases in the app |

Note: The same app update also adds per-game Resizable BAR controls in Driver Settings, G-SYNC Pulsar settings under System > Display, and Borderless Windowed support for Optimal Playable Settings.
What the new model changes
Ray Reconstruction unifies denoising and Super Resolution into a single AI network trained on Nvidia supercomputers. It fills in higher-quality pixels where rays were not sampled, then reconstructs a sharper, more stable high-resolution image using motion and engine data. The second-generation transformer brings four concrete gains.
| Improvement | What it does |
|---|---|
| Efficient denoiser | 35% more compute capability and 20% more parameters at similar performance to the previous model |
| Enhanced Super Resolution | Better lighting accuracy, temporal stability, and clearer motion in ray-traced and path-traced content |
| Expanded training dataset | Picks more accurate engine data to reconstruct scenes closer to ground truth |
| Finer developer control | Precise tuning of temporal accumulation for individual effects |
In practice, that shows up as cleaner particle effects and reduced snow ghosting in Indiana Jones and the Great Circle, more responsive laser lighting with fewer leftover artifacts in PRAGMATA, and steadier CRT static in Alan Wake 2.
Games that support it now
The updated Ray Reconstruction model can be applied to 30 titles through the Nvidia app right now.
| Alan Wake 2 | Enlisted | NTE (Neverness to Everness) |
| Avatar: Frontiers of Pandora | EVERSPACE 2 | Portal with RTX |
| Backrooms: Escape Together | F1 25 | PRAGMATA |
| Call of Duty: Black Ops 7 | FBC: Firebreak | Resident Evil Requiem |
| Crimson Desert | Half-Life 2 RTX | Samson |
| Cyberpunk 2077 | Hogwarts Legacy | Star Wars Outlaws |
| Death Relives | I Am Jesus Christ | Subliminal |
| Directive 8020 | Incursion Red River | Sword of Justice |
| DOOM: The Dark Ages | Indiana Jones and the Great Circle | The First Descendant |
| Marvel’s Spider-Man 2 | NARAKA: BLADEPOINT | War Thunder |
Developers are also adding the model directly through their own game updates, so the list keeps growing beyond what the app overrides on its own. Various RTX Remix mods are joining too, including the Quake III RTX mod and Painkiller’s RTX Edition, with an Elder Scrolls III: Morrowind RTX mod in development.
Upcoming games adding it at launch
Two major titles are set to add DLSS 4.5 Ray Reconstruction and path tracing next month. Control: Resonant becomes the first big AAA game of 2026 to include the upgrade at launch.
| Game | Date |
|---|---|
| 007 First Light (path tracing and Ray Reconstruction update) | September 15, 2026 |
| Control: Resonant | September 24, 2026 |
Phantom Blade Zero and Gears of War: E-Day are also lined up to receive support, with the latter pairing full DLSS 4.5 with new RTX Mega Geometry. No confirmed dates have been set for those two yet.
Once you have applied “Recommended” or “Preset F” and launched a supported game, the cleaner denoising should be visible immediately in ray-traced scenes. If the option is missing, make sure you are on driver 580.88 WHQL or newer and that Early Access is switched on, since the model does not download until you opt in. A wider public release lands in September, so the same feature will reach every RTX user without the Early Access step soon after.
