I'm not sure who, but someone asked if I think Shadow is still a good option for gaming given their tier card and the current GPU market and the cost of the Shadow service. They removed the question for whatever reason, but I will still answer it!
That answer is, it depends. If you need a Windows environment that you can log into from almost any other machine, but one you can still game on, then yes. However, it is not a good option for gaming. You could do a lot with the $30+ a month, such as put it toward a prebuilt PC.
Don't get me wrong, it has a use-case, and a lot of people who use a paper space machine might find this to new a good alternative.
