Nvidia DLSS 4.5: AI Upscaling Reaches New Heights

Nvidia revealed DLSS 4.5 at CES 2026, introducing a significant advancement in its AI-driven performance suite with a new 6x Multi Frame Generation (MFG) mode. This iteration moves beyond basic upscaling to generate a higher ratio of interpolated frames, theoretically boosting average framerates by up to 50%.

Initial testing suggests that while frame generation does improve performance, the actual gains are inconsistent. Factors such as specific PC components, display resolution, DLSS settings, and in-game graphics configurations heavily influence the results. The technology, exclusive to newer Nvidia RTX GPUs, continues to face criticism for its AI utilization and potential impact on game optimization.

Despite ongoing controversy, Nvidia has iteratively improved its frame generation technology since its debut with DLSS 3. Early adoption of 2x MFG mode has shown tangible framerate increases with minimal visual degradation in various titles like Alan Wake II and Avowed. While higher MFG modes still present challenges with visual artifacts and latency, the evolution of DLSS suggests a maturing technology with increasing potential for gamers.
