Windows 10.
Thankfully the bugs have not been major. Stuff like an NPC going through a floor, a door not opening or a stolen car disappearing while I was in it. Visual glitches are numerous, like things popping in or disappearing as I get near them. Crashing has been less frequent since disabling RTX, but still happen occasionally. I use them as a good excuse to stop playing.
I still love this story and setting. Like I said, I dream about what could have been.
I'd be curious to understand what Qwant brings extra to the table compared to DDG. Backend is the same, results seem quite similar and it's missing some things like math and conversion quick tools.
