Nvidia DLSS Analysis

Eurogamer posted an analysis of Nvidia's DLSS tech found in their Turing graphics cards, and the results are interesting. DLSS does boost game performance significantly in some cases, while still providing good image quality. The author points out that Final Fantasy 15 ships with a particularly blurry temporal AA implementation, and running DLSS instead provides a image quality boost in some areas. Check on the screenshots comparisons on Eurogamer's website, or watch video below:

The Infiltrator demo also serves to highlight that the performance boost offered by DLSS is not always uniform - it's not a straight 35-40 per cent uplift throughout. The demo features a number of close-up scenes that stress the GPU via an insanely expensive depth of field effect that almost certainly causes extreme bandwidth issues for the hardware. However, because the base resolution is so much lower, the bandwidth 'crash' via DLSS is far less pronounced. On a particular close-up, the DLSS result sees the scene play out over three times faster than the standard, native resolution TAA version of the same content. But has Nvidia truly managed to equal native quality? For the most part, it passes muster and inaccuracies and detail issues are only truly noticeable when conducting direct side-by-side comparisons - but we did note that in the demo's climactic zoom-out to show the high detail city, the lower base resolution does have an impact on the quality of the final image. Is it likely to distract a user playing the game and not conducting detailed side-by-side comparisons? Highly unlikely.
