Great port, I'm running everything ultra at 1440p and getting really great performance (network bugs aside).
Average fps around 100/110 fps (lowest I've seen is around 80ish, highest around 170). Really great to see such a good looking and clean game run so smoothly. And it's pretty fun too.
The level of control you have is really great; fov, min fps, max fps, full statistics, and a lot of options. That's how you release a game on pc.
Game pass is making the win store look good. And the new app is pretty slick.
