DLSS 4 Upscaling at 4K is Actually Pretty Amazing

The most interesting aspect of Nvidia's new RTX 50 series is not the GPUs themselves – not even close – and it's not multi-frame generation either. It's DLSS 4 Super Resolution upscaling, which has received a substantial update aimed at improving visual quality. The old CNN AI model has been replaced with a newer, larger Transformer model, which Nvidia claims can achieve a level of quality that wasn't possible with previous versions of DLSS. So how good is DLSS 4 upscaling? Let's find out. Deeply analyzing upscaling technology is a massive undertaking, so today's focus is on DLSS 4 versus DLSS 3 upscaling at 4K resolution. We have data for 1440p and 1080p upscaling as well, but that's something we plan to revisit later. The goal here is to determine where DLSS 4 has improved, where it struggles, and what the new acceptable minimum quality level for gaming is. Previously, we found that for the best experience, you likely wouldn't want to drop below Quality mode at 4K – maybe Balanced ... Read full article.
