The game limits us to a resolution 1280x1024 unfortunately for certain level it can be useful for certain person

Here is how to change its resolution from 4: 3 to 16: 9 or other:

1. Win + R and typed "regedit.exe"
2. Go to the HKEY_LOCAL_MACHINE folder
3. Then in the "SOFTWARE" folder
4. For those with a 64-bit pc go to the "WOW6432Node" folder for those with a 32-bit pc I believe you do not have a folder of this type
5. For some people the file is called differently for some it is "SCi Games" and for others it is "Pivotal Games"
6. Then in the "The Great Escape" folder
7. Then click on the "Device Settings" folder 8] Normally you will have a file called "ResolutionIndex" double-click on it then you will have a window with marked a value to modify, you check the box "decimal" to change the figures to decimal it is mandatory
8. Then enter a value that corresponds to your need: 24 - 1152x648 25 - 1280x768 26 - 1280x720 27 - 1280x800 29 - 1280x1024 30 - 1360x768 31 - 1360x1024 32 - 1364x768 33 - 1440x900 34 - 1600x900 35 - 1680x1050 36 - 1776x1000 37 - 1920x1080 16 - 2560x1440 19 - 3840x2160

It rarely works, these guides may be useless for some people
