Nvidia officially announced and released the DLSS 4.5 Ray Reconstruction update in August 2026, making it a free upgrade for all GeForce RTX GPUs worldwide [1, 2]. The update introduces a second-generation Transformer architecture that replaces the previous convolutional neural network used for ray tracing denoising and upscaling [1, 2].
This new AI denoiser model increases the number of processing parameters by 20% while boosting computational efficiency by 35%. These improvements enhance lighting accuracy, temporal stability, and motion clarity in both ray-traced and path-traced visuals [1, 2]. Developers also receive expanded control over temporal accumulation settings to fine-tune the visual quality in supported games [1].
At launch, DLSS 4.5 Ray Reconstruction will have native support in 27 top-tier games including Cyberpunk 2077, Doom: The Dark Ages, Alan Wake 2, Resident Evil Requiem, Indiana Jones and the Great Circle, Hogwarts Legacy, F1 25, and Call of Duty: Black Ops 7 [1, 2]. Several upcoming titles will add support through updates or at launch later this year. These include the Chinese action game Shadow Blade Zero, Marvel Contest of Champions, and Naraka: Bladepoint [1].
Naraka: Bladepoint already received a DLSS 4.5 Super Resolution upgrade in June 2026, followed by Marvel Contest of Champions adding DLSS 4.5 Super Resolution and Dynamic Multi Frame Generation later that month [1]. Shadow Blade Zero is scheduled for release this fall with DLSS 4.5 Super Resolution and ray tracing support [1].
The rollout this August marks a significant upgrade in Nvidia’s AI-driven ray tracing and upscaling technology, available across their RTX lineup at no additional cost. Users can expect clearer graphics and smoother motion effects in both new releases and established games that update to the new model.
