Not only does the game crash, but discord crashes, and I have to power down my PC by holding down the button. This did not happen prior to the latest update.
Verify your game files in Steam (right click on game in Steam, click properties, local files, then VERIFY INTEGRITY), and delete your Rising Storm 2 folder in Documents\My Games\Rising Storm 2 (or rename this folder to keep a backup of it, it contains all the cache and config files). See if that help. Seems more like your computer is dying than a problem with the game but that doesn't hurt to start fresher than you are currently.
