OK, so I have now tried out GeForce Now with mixed results.
I thought I'd have a go on Metro 2033 to see what those Ultra graphics could look like. I found the game, clicked on play and... it took me to the Steam login page. But I have it on Epic and it says Epic games are supported so why is it taking me to Steam?
After a bit of googling I find that only some Epic games are supported. Like Fortnite!
So all my Epic freebies are unplayable even though the games ARE listed.
So I went back to my Steam library. Skyrim IS supported and the thought of some maxed out lollygaggin' is obviously appealing to me but I've modded that and have a bit of DLC so all of my saves aren't gonna work and a new game might corrupt my current 130+ hours of play.
What else can I try?
Dirt Rally? Not the one I have.
Grid 2? Nope.
Deus Ex?
Bioshock Infinite? Yes but I don't want to touch that until I've finished the previous ones.
Arkham Asylum then. Yay.
And you know what? When you find something to run it works fine. 1080 (better than my usual 720 or less.) Max settings (although my normal settings are pretty good for that game anyway.) And no discernible latency. The compression blurs the distant textures a little but nothing too bad. Quite satisfying, in terms of performance.
If I could play all the other games it'd be great, but until then...
LATER EDIT: Back to my normal style of gameplaying with The Witcher and look who's finally turned up at the Inn!!
About [SWEAR WORD] time!!
His appearance coincided with one of those strange quest glitch things. I talked to the detective and got some clues that advanced a quest. Then I stepped outside his house, checked my journal and found that the quest hadn't updated.
Maybe I didn't ask the right thing. So I went back inside and found him fighting off a load of assassins!
Where the hell did they come from? I was stood in the doorway so they didn't sneak past me. Maybe they were hiding upstairs under the bed.
Anyway after that I went back to the Inn and the messenger's suddenly there!
I saved it at that point, it's too late for drinking games.
