I just tried to start this game through Steam, and it wouldn't launch. I tried the CPU Affinity fix, as detailed for Tomb Raider: Underworld (https://steamcommunity.com/app/8140/discussions/0/2791621786941084149/), and that allowed the game to Launch properly.
I tried Temple of Osiris as well, and it crashed when set to all cores, but when set to 30 or fewer it seemed to run fine.
So Tomb Raider Underworld, Lara Croft and the Guardian of Light, and Lara Croft and the Temple of Osiris all seem to need steam's affinity set to 30 cores or lower to run properly.
