Tried it out on a 5-year-old laptop w/TW:3K, FC:Primal, and W3. No wait to get on the free service and I was able to play all three games over the wireless without any trouble.
After launching GeForce Now it launches Steam to verify you own the game. You have to click install, but it doesn’t download anything to your system. Something is happening, though, because W3 took a lot longer to load than the other two.
Each game had the graphics set to Ultra, and I was able to modify resolution and other options. Load times also seemed improved compared to my old laptop. Best of all, my laptop’s temperature stays low while the game’s running.
My Steam saves worked just fine. Tried to get the app running with Game Pass for PC, but no luck there. Haven’t tried it with Epic yet, but I might give Kingdom Come a go later this week.
I can definitely see myself signing up for this next time I’m playing a compatible game.
