Hello, I'm the developer who added FSR and implemented other post-processing options for this release. I think there's a couple misunderstandings here.
QuoteThe Yuzu Nintendo Switch emulator recently received a major overhaul to its resolution scaling feature.
Just to be clear, the old resolution scaling feature was removed some time ago because it interfered with other important improvements to the rendering backends. So we haven't had it in awhile.
QuoteSurprisingly, the initial screenshots shared by the Yuzu dev team indicate that FSR scaling seems to deliver better image quality than the old resolution upscaler with bilinear filtering enabled. In the screenshots, we see FSR better reproduce high frequency detail in the Metroid Dread comparison, despite running at a lower nominal resolution.
We are not running any comparisons against the old resolution scaler. Both the bilinear and FSR comparison images are being rendered at the same resolution, but the comparison shows that FSR does a much better job of scaling that low resolution image to the window resolution than plain bilinear filtering.
