Thanks to the op for making this and to the member who wrote the tutorial. Some observations from one who has not yet downloaded it:
If timing for weapon reload/fire rate is a given value then perhaps changing it to a slightly faster value but not obvious would be the way to go. No one is going to get banned for guns that fire 33% faster but it still give you quite an advantage over stock guns.
Do the anti-cheat methods in the dll need to be deleted or are they unable to detect the changes made here?
Does the CE speed hack still work with low values like 1.15?
