I went into this game pretty blind( only became slightly interested in it after seeing that digital foundry made a video about it), and having played about a half hour of it, it's certainly an interesting game. PC settings are minimal as we only get to turn anti aliasing on/off, modify shadow detail low - med- high and change in-game resolution. By using MSI afterburner, I see that this game is on dx12 which is pretty interesting. However I notice that with my Ryzen 2600, one of my cores regualry high as 100%(on 1440p resolution), so this game is probably single threaded. Even with that cpu and a rtx 2070 super I can't get a stable 60fps with 4k resolution as sometimes the fps drops from 60 to 48.
Another thing to note is upon launching the game it'll tell you to go from 144hz to 60hz if you have that type of monitor. I set fps to 60 in rivatuner, but this is still annoying to deal with as the game doesn't use a ingame fps limiter.
I've became so accustomed to 60fps+ that anytime i see 60fps in a game like say, AC origins or just about any other game, it looks horrible. However Halo 5 and this game apparently still looks pretty good at 60fps, so fortunately that's not a deal breaker for me.
I don't think they are obligated to just stay on Windows Store so maybe this game will go on Steam one day, but it's still perfectly playable on Windows Store.
