Chronicles of Narnia Update updates the game to the latest version.
The game natively supports only 2 widescreen resolutions: 1280x720 and 1600x900. To use any other resolution, you have to open the game's configuration file, then search for the lines NU_PCRESW and NU_PCRESH. Change the number next to NU_PCRESW to the desired horizontal resolution (e.g. 1920) and NU_PCRESH to the desired vertical resolution (e.g. 1080). Then run the game and in the options menu, change the option that says Widescreen to On to expand the FOV.
Install the Chronicles of Narnia Update.
Capping the game at 30 fps will prevent this minor issue.
