DLSS 4.5 Reveals Performance Disparities Across NVIDIA GPU Generations
The latest iteration of NVIDIA’s Deep Learning Super Sampling (DLSS) technology, DLSS 4.5, is generating considerable discussion within the PC gaming community. Initial testing has highlighted a significant performance gap between newer RTX 40 and RTX 50 series cards utilizing the enhanced transformer model and older RTX 20-series GPUs. While DLSS 4.5 delivers markedly improved image quality compared to previous versions, its impact on lower-tier hardware is substantially less pronounced, raising questions about optimization and future development priorities.
