The game runs very choppy if futex or futex 2 is enabled. It runs smooth with esync. steam-522470.log
[EDIT] After little more testing. With esync enabled the game is much less choppy, but still not optimal. Disabling esync too fixes the issue. It seems it doesn't like synchronization primitives at all!
Nothing extracted yet.
