How is Orebfuscator laggy?orebfuscator is laggy, but it can prevent xray mod users from hacking. Unfortunately there is no way of stopping people from using texture packs, since minecraft renders all exposed faces. And the server textures option is optional for players, they can choose to not download the texture pack. Best thing to do, get moderators to check up on suspicious players while invisible. It can be pretty obvious some times when a player is using an xray texture pack.
I dont know about bukkitforge compatibility, but some plugins like anticheat can catch hackers sometimes.
