Sorry what? Anyone with an RTX card can try both themselves, what "game" are you talking about? The denial game? Also, again, i'm not someone else's alt account.
@Poneros Yes, rain and in general particles will be better by not using DLSS. It's one of the disadvantages of reconstructing an image using Deep Learning. Does that invalidate everything else? No. Does that make FidelityFX better? No. The screenshots show everything there is to show. Again, anyone with an RTX card can try both at 1080p and see how each tech works. DLSS actually reconstructs the image, FidelityFX only sharpens and upscales. The wires and generally any edges are a mess without DLSS.
Same thing happens at 4k, both techs work the same as they do at 1080p. Obviously there's more pixels to work with so the wires won't look discontinued like in 1080p with FFX but the shimmering is horrible even there.
