What do you mean "proper" upscaling? Is DLSS the only "proper" upscaling? Plus, they've highlighted that DLSS is better than other options repeatedly, from what I've seen.
I think there's good arguments to criticize their discussion of latency when Nvidia had reflex and AMD had not release anti-lag+ yet.
DLSS is one of these PC gaming archivements which has transformed how we play games. It is on the same level as 3dfx Glide (and Voodoo cards). Now look how this channel has approached upscaling. For them it is "native" rendering only.
"Realism" depends on the artist. When an artist wants reflections why is SSR acceptable but hardware raytracing isnt? Do you think a game with missing reflections is looking better than having "realistic" ones?I don't know exactly what this means, so I'm just going to talk about raytracing support. Raytracing is a visibility test with pros and cons. You can have complex visibility tests, but normally at the expense of resolution, performance and noise. It can provide elements of realism in light "transport" that other methods cannot handle as accurately. Realism is not objectively better. In fact some people have very good arguments about why realism is bad for graphics.
See this thread for a discussion on image formation vs physically based rendering etc (read back through more of the thread than the thumbnail)
DLSS and Raytracing are tackling different kind of aspects of rendering. Independently both representing the exact opposite of the gaming spectrum.
So with this in mind its a paradox with this channel: They dont like better image quality and they dont like more performance withlower lantency. So what do you they like? I guess every option which makes AMD GPUs look better.
