How does Stadia strike you as an alternative? It works on anything (AFAIK) that runs Chrome.
I tried GeForce Now with a high speed internet connection (Comcast) with Counter-Strike and I found the game to be unplayable from the lag. I double checked my speed test and router settings, it should’ve been fine. Ultimately I believe these services represent the future of gaming, but without net neutrality or alternative ISPs it’s going to be awhile before that future is realized.
E.g., my RTT to my ISP's gateway, on average, fluctuates between 8-11 ms (currently ~14 according to pfSense) and a ping to google's closest response is usually about the same. I'm sure others have it better, but I am quite impressed, given a little bit of this latency would probably be eliminated by not having a virtualized router as is the case with my setup.
Twitchy MP shooters and twitchy platformers are the 2 subgenres that aren't suited for this arrangement. Most everything else is perfectly fine (under the aforementioned ideal conditions).
