Overview
- Nvidia announced DLSS 4.5 Ray Reconstruction at Computex and said the second‑generation transformer denoiser will be available in August with injections into 27 games.
- The new model processes about 20% more parameters and delivers roughly 35% more compute work while keeping similar run-time performance to the previous RR model.
- Nvidia says the update was trained on a larger dataset and gives developers finer control over temporal accumulation to reduce artifacts and improve lighting stability.
- Several developers are already issuing DLSS 4.5 updates in early June for Super Resolution and frame generation, with fuller Ray Reconstruction support scheduled for the August rollout.
- DLSS 5 did not appear at Computex, leaving its status unclear and prompting industry and community questions about whether Nvidia will revise or delay that separate initiative.
