I recall the streaming thing from when I read it back in 2015. Since then, NVidia GRID has appeared, which does appear to support streaming from any NVidia based GPU to any machine (possibly any NVidia machine). That may be how Snoost does the streaming, but I didn't go looking for how NVidia GRID works last night, since it was past midnight and I wouldn't be able to understand a thing.
So yes, depending on how the streaming is done, it may work with GOG games. Or it may not.

The Snoost pages mention also Origin and Uplay ("etc.), so do they have some specific "game streaming technology" included as well that that system might use? EDIT: Ok you mentioned it uses some GPU specific technology; the pages do mention the cloud computers apparently run on NVidia GPUs.

I took it to mean that Snoost just offers a high-power cloud computer (capacity) which you can use any way you want, but then I don't know if some specific technology needs to be supported (by the games, or the gaming client) for it to work? The only requirement I saw mentioned was that it all happens through a Chrome browser (hopefully Chrome is available for Linux distros too; when I searched for Chrome for my old Linux box, it offered only Chromium, the open-source version of Chrome; not sure if it works too with Snoost).

I guess the OP just has to try the system with the free 3 day test period. I might also try it for shits and giggles, but I dislike these subscriptions which start automatically after the free period, and if they have made it intentionally cumbersome to cancel the subscription, making people to jump through the hoops.

EDIT: The Snoost pages claim that the only requirements for the client machine (where you will be playing) are:

- Minimum 4Mbps stable internet connection
- A Chrome browser
- supports "hardware decoding", whatever that means in practice.

They say it should work on Windows, Mac and Linux PCs alike.

Well I will try the free trial and see how it works with mt GOG games ! I just bought Distant Worlds Universe before my virus and operating system issue. That I have not really gotten to enjoy it and if I need to pay a monthly fee for me to play it and my son to play Rainbow Six Siege then so be it.

GOGs only have cloud saving through Galaxy and only specific games support it (there'll be a little note saying "cloud saves synced" on its page in Galaxy).

So... instead of fixing your virus/OS issue, or even buying a new PC to play your games on... you rent a cloud computer to stream the games you already own?

Umm... ok I guess that is one possible solution. I personally would go the other suggested routes, but to each his own, your mileage may vary, do unto others as others undo you etc.

[EDIT]

Thank you for showing me this. AS is it looks like $ 0.5+ an hour would be a more reasonable price match for me.Playing games only paying if I am playing works better in the long run. Monthly sound decent but I rarely would have the time to play enough to make it worth while

For me the downside is rather the price. Up to $40 per month and I still have to buy the games before. Are they crazy? Do they think I consist of solid gold?

Thanks but no. For that money (for a year or two) I can buy the hardware they have myself. Much, much smarter.

I don't think it's a particularly good idea.

Hmm. This sounds like a lot of speculation. There are many different streaming libraries out there. Might be the case, might not be the case. I would like to have more information about the technology they use but I would rather not speculate too much about it. Or are there some citeable sources?

As I said to timppu before, that was me recalling an article I had read a few years back and posting it at ~02:00 (similar to this post). Quick look to find it again showed that there is now a hardware based streaming method, which may have replaced the In-Home Streaming, but I didn't have the time (or the will) to go looking for more info back then. And I'm not really aware of that many different streaming libraries (that allow you to play the game, not stream video), but if you are aware of others, do tell. Always nice to have more info.

I wonder why this post got down rated.

Cloud gaming technology have developed at least 18 years.

Usually downrating means disagreement, sometimes also a judgement of poor quality, but in most of the cases it's just simple disagreement.
