The cause of Prototype 2 crashing when running on a Windows 10 PC

Hyperthreading and MultiThreading: If you are using an AMD or Intel processor with Hyperthreading or MultiThreading enabled by default, this is most likely the cause of the game crashing. In this case, you need to go into the BIOS or EUFI settings and disable this option.

Game file inconsistency: If you run the game via Steam, you should check the game’s integrity via Steam and see if you find any inconsistencies. Several users who have encountered the same problem have confirmed that after performing this action, the game eventually launches normally.

Minimum requirements not met: If this problem occurs on a very old configuration, the game may hang due to insufficient power from your GPU or CPU or insufficient memory. Check the minimum requirements to make sure this is not the case.

Conflicting HID-compatible control drivers: Prototype 2 was developed before the Windows 10 era, so it doesn’t know how to use the new control drivers. Also, if you leave these drivers enabled, the game may crash. Therefore, it is best to use Device Manager to disable these drivers while playing the game.
