There used to exist a GeForce Now version (branch) viewable on SteamDB that was added back in August but it has since disappeared in October. I wonder what happened to it?
Even if the experience is less than ideal, not everyone has latency issues with streaming services, and as long as you are near to the servers providing the stream and have a straight shot to them it'll work well enough. They'd just be the data caps to contend with in countries that unfortunately have them.
New Genesis drops Perfect Attacks so there's less timing required with attacks. Dodging and Perfect Guarding will be a bit trickier though with the stream latency.
