Anyone finding it a bit of a crashy mess? We could compare notes and they'd know where to look? :)

yeah! the games crashes in the first mission (after the tutorial) in different parts of that mission. i also notice that the game uses 99% of the GPU (i have a 1070), so its very bad optimized.

Same here, the game freezes at random spots a lot, mostly when player's turn is announced or on loading screens.
On a subjective level I have the impression that the likelihood of a freeze is reduced if I change my power profile to high performance (CPU should not under volt or cycle down so much) and if I switch my anti virus suit (ESET) to game mode.
