I'm using Steam streaming to play the game on my MacBook Pro. The host machine is an i5 desktop with 16 GB of RAM and an nvidia 760 GTX. I'm running into some issues with this: 1) It occasionally won't show Load Game or Continue at the starting menu. Rather, they're grayed out as if I've never played the game. To fix this, I seem to need to open another game, then reopen Pillars. 2) It sometimes will not fill a 16:9 area of my screen, despite the resolution set for 1080p. Readjusting the resolution at least fixes this.
