How much changed? I didn't yet buy it because 35€ is too much for me, but I saw a playthrough (I didn't expect back then to have a device so soon which actually had a chance at running it lol).
Finished it before 2.0 released. Had a lot of fun, even though I had to set everything to the lowest possible, including resolution downscaling. Now that 2.0 was released, I wanted to play through the story again but I just couldn't. The lag was too unbearable and made the game unfun.
However, I subscribed to a cloud gaming service and am having a blast! Everything cranked up to max + RTX with minimal input latency. I was honestly impressed by how far the streaming technology has come.
The game itself feels and plays even better. A lot of annoying stuff has been fixed and reworked. There are still bugs, though.
Just finished basically every activity available and started the very beginning of the DLC. So far it's amazing, even cooler than the main story.
