I'm struggling with GeForce Now. I have a decent broadband connection (generally 60/70 mbps) but I always get spotty connections, with blurry graphics. There doesn't seem to be much lag, it reacts well to m&k inputs, but the picture quality is poor. I used their test tool thingy, and on the back of that I bought a signal booster to get a better signal in my gaming room but it hasn't helped - I often seem to be recording decent mbps outside of GeForce Now (just checked and I'm at 60) but it doesn't seem to help.
In the same room, I've tested the opening area of DOOM Eternal on Stadia and it works and looks fine, a much better experience. But I need GeForce Now in order to play ELEX! The Nvidia forums aren't much help, so I'll just have to keep fiddling with it (I think packet loss is next on my list of "stuff I don't really understand but need to look into")…
