NVIDIA DLSS 4.5 Ray Reconstruction Is Landing at Gamescom — a Free Upgrade for RTX Owners
NVIDIA's "GeForce On" event at Gamescom 2026 (today) is expected to officially launch DLSS 4.5 Ray Reconstruction — the next iteration of its ray-tracing denoiser, built on a second-generation Transformer model. The promise: better image quality, temporal stability, and lighting accuracy in ray-traced games, delivered as a free driver update.
What Ray Reconstruction actually does
Ray tracing is expensive, and even the best GPUs can't render full ray-traced scenes cleanly at high frame rates. Ray Reconstruction is the AI that fills in the gaps — replacing the traditional denoiser pipeline with a model that reconstructs the scene from noisy ray-traced data. DLSS 4.5's second-gen Transformer model should mean fewer artifacts, more stable images in motion, and more accurate lighting, especially in demanding RT-heavy titles.
Who gets it
If you own an RTX 40-series or 50-series card, this arrives via driver update — no purchase, no hardware change. In a hobby where "upgrade" usually means "empty your wallet," a free visual upgrade is the rarest species of good news. The 50-series cards (see our GPU guide) get the most out of it, but 40-series owners benefit too.
What to expect at Gamescom
The Gamescom event is software-focused: DLSS 4.5 and gaming integrations. Don't hold your breath for surprise RTX 50 SUPER hardware — this one's about the software stack. If you own an RTX card, grab the new driver when it drops and enjoy the free frames and cleaner image.
Our take
DLSS is one of those technologies that keeps proving its worth generation after generation. NVIDIA's upscaling lead is a genuine reason to pick an RTX card over the alternatives, and 4.5 extends that lead. The real test is whether the second-gen Transformer model delivers the promised stability improvements in motion — but if it does, this is the kind of update that makes an old card feel new.
