Nvidia unveiled the RTX 50-series range of GPUs at CES 2025, but we had the chance to take a quick look at DLSS 4 running on an RTX 5080 over the preceding holiday break. Here’s a look at DLSS 4 super resolution and ray reconstruction improvements stacked up against the existing technology, plus a look at the new Frame-Gen 3x and 4x options and some frame-rate, consistency and latency comparisons. A few notes: Super resolution and ray reconstruction comparisons taken with frame generation disabled and with CP2077 post-process features (chromatic aberration, film grain, motion blur etc) disabled on RT Overdrive mode. All b-roll uses frame-gen 3x, RT Overdrive mode but again with post-process features disabled for improved clarity. Frame-rate clips captured on RT Overdrive but with film grain disabled for better image quality on YouTube.
