I doubt it, I run much more grapicly intense games, with many more players (Like War Thunder, DOTA 2 and TF2) It only shuts down when I play FeralHeart, its NEVER done this in the past. Only started after the update.Wow, that's really strange. :/
Either it as a corrupted driver FH has, (As I own an IT server that never cuts my computer off) or possibly the mods (Which are nothing but items and markings) that screw with the new FH update. Im currently testing this on two other computers in hope of figuring out the problem and no, nothing sounds like it changed besides the normal spurts of my fan spinning faster whenever I arrive in a super croweded area but this has always happened even during other gameplay.
