NVIDIA Unveils DLSS 4.5 Ray Reconstruction for "Superior" In-Game Image Quality, Coming This August

Ray tracing has looked impressive for years, but it has never been perfect. Ghosting, blurry lighting, flickering reflections, and noisy shadows still manage to sneak into some of the biggest PC games. NVIDIA now says it has a fix coming later this summer. The company has officially unveiled DLSS 4.5 Ray Reconstruction, a major upgrade at improving image quality in ray-traced and path-traced games. This update is all about making games look cleaner, sharper, and more stable while you play.

NVIDIA wants Ray tracing to look closer to the real thing

The announcement revolves around the new, second-generation transformer model designed to replace traditional denoisers used in ray-traced rendering. According to NVIDIA, the upgraded model combines denoising and Super Resolution into a single AI-powered process. The result is improved lighting accuracy, clearer motion, better temporal stability, and higher-quality image reconstruction across complex scenes.

The company says the new Ray Reconstruction model delivers 35% more compute capability while processing 20% more parameters without increasing performance costs compared to the previous version. It has also been trained on a larger dataset, allowing it to make smarter decisions when rebuilding missing visual information.

Cleaner reflections, better lighting, and fewer visual artifacts

NVIDIA showcased several examples of the improvements. In Indiana Jones and the Great Circle, the company says snow ghosting is significantly reduced while particle effects appear cleaner. PRAGMATA reportedly benefits from more responsive lighting effects, while Alan Wake 2 shows improved preservation of fine television static details without losing clarity.

Developers are also getting more control over temporal accumulation settings, giving studios additional tools to fine-tune image quality based on their own games.

DLSS 4.5 Ray Reconstruction is scheduled to arrive in August for all GeForce RTX GPUs. NVIDIA says 27 games will support the technology at launch, including Cyberpunk 2077, Alan Wake 2, Resident Evil Requiem, Indiana Jones and the Great Circle, and DOOM: The Dark Ages. In another company news, NVIDIA has also announced its latest RTX Spark processor.
