Title: DLSS 4.5 image quality and performance analysis: 2nd gen Transformer brings improved visual fidelity with hidden performance penalty
Post by: Redaktion on January 20, 2026, 09:45:16
With DLSS 4.5, Nvidia is introducing its 2nd gen Transformer model that aims to offer sharper and more temporally stable images. We put four demanding AAA titles through their paces at 4K max. settings to see how the new upscaler stacks up against DLSS 4 and native resolution. While the results seem promising, the benefits are not without cost.

So I thought your image comp widget is broken because diffrent aspect ratios of diffrent phones.
But not it just broken and useless as here it does not work eihter. I point at the rock on one pic and no way I can get it in view in remaining 4 windows. Just fix it finaly.

No mention whatsoever about the fact that dlss 4.5 does not work with ray reconstruction. For example in CP2077 It reverts to mode D if you apply path tracing and RR.

It's mentioned in the article
"It is worth noting that RR still uses the original Transformer model, so enabling it in-game basically kicks you back to DLSS 4."
