At CES 2026, NVIDIA, the world's largest company by market cap, unveiled DLSS 4.5 with Dynamic Multi Frame Generation, setting a new benchmark in gaming upscaling technology. This announcement came shortly after AMD released its highly competitive FidelityFX Super Resolution (FSR) 4 in late 2025. AMD's Redstone update was a major leap forward, finally providing a worthy competitor by integrating a machine learning algorithm into FSR for the first time.

The update also introduced an improved Frame Generation algorithm, plus two new technologies: Ray Regeneration, which mirrors NVIDIA's DLSS Ray Reconstruction, and Radiance Caching, a technique that appears similar to NVIDIA's Neural Radiance Caching. This escalating technological arms race means gamers can expect unprecedented frame rates and visual fidelity across all hardware tiers. The competition between NVIDIA's established DLSS and AMD's revitalized FSR will drive rapid innovation, pushing the entire PC gaming industry toward a future where high-performance ray tracing is accessible to a wider audience.
