Q : Why is my test build not always scaling correctly (standalone game Windows 7) ?
That is because of the 'user preferences' that are stored somewhere on your computer ! You need to delete the 'old' preferences, rebuild, and then test.
A build for a Windows standalone player leaves traces in the Windows registry.
To delete the entry, click the Windows start button, and type 'regedit' in the search box.
Under 'HKEY_CURRENT_USER' > 'Software' > find the name of your game > right-click & delete.
And partly related to this : do not forget to uncheck 'use player log' in the
project settings > player menu before building the final game !
Excessive logging may slow down your game ...
