Pour Sweetfx, j'ai posé la question a Punkbuster
on m'a répondu ça:
"Hello,
PunkBuster is designed to specifically catch cheat programs running in memory at the time a game is being played. Any process which modifies or manipulates the game may at some point be considered a cheat.
Modifications not intended by the game developer/publisher can be seen as cheating and may at some point be banned for.
You will need to contact the game developer/publisher to find out what game modifications are acceptable for use.
In general, you should shutdown all unnecessary applications/processes/services on your machine before connecting to a PunkBuster enabled server. This is the best way to insure that nothing on your system is interfering with PunkBuster."
J'avais posé la question par rapport à SweetFx sur BF4 (j'avais mis un lien du site dans mon mail)
C'est une réponse sans en être une...vague.
Donc faut demander aux incapables de chez DICE...
