Direct3D or OpenGL graphic rendering disable via DLL

I am in search of someone to create a .dll that can be injected into a game that is in beta called Trove that will return prior to all the graphic rendering calls so that it will not put a strain on my computer running multiple at once. All the .dll has to do is inject, reduce the graphic load on the computer by having no renders while still letting the game run it's main loop so that it can function and still communicate with the game server.
