Nvidia dropped official support for gamestream (IIRC), but
Moonlight is still alive and well. Thanks to
Sunshine, you can even use it with an AMD GPU on the host, which doesn't even have to run Windows. I use this software daily. It's by far the best option for in-home streaming, certainly for games, but it also works for remote desktop. Every time this topic comes up, in fact, I'm reminded of how brutally inferior Steam's variant of in-home streaming is.
The gamestream thing is illustrative of the whole story here. History shows that Nvidia tends to innovate with some (semi-)proprietary feature, which is then improved upon and/or opened up by other players, notably AMD (e.g. Freesync), and then finally the entire user base benefits. We were potentially on track for a similar story with FSR, but AMD just didn't have the juice. It's still possible, I suppose, that major game studios and GPU manufacturers will come to some sort of agreement to standardize upscalers, once enough time has passed with a sufficient number of GPU generations featuring the requisite hardware--or if not the upscalers themselves then the workflow to implement them. My understanding is that DLSS and XeSS aren't all that dissimilar from a game developer's perspective, even now.
Both companies (or I guess all three companies, these days) play a crucial role in the GPU market, which is why I hate seeing AMD make so many unforced errors.
