The slider for distortion and FOV effects in game does not reflect that of the options.txt file.

How to reproduce:
1. Set FOV effects to 10%
2. Open options.txt and locate the field fovEffectScale
Results: The file says the value is set to about 0.32 and then a bunch more decimal values.
3. Set distortion effects to 40%
4. Locate the field screenEffectScale right above fovEffectScale
Results: The file says the value is set to about 0.408, almost 0.41.

Additional Information
By changing the value after fovEffectScale to 0.32 and screenEffectScale to 0.41, the FOV effects slider would say FOV effects is set to 10 and distortion effects is set to 40.
