Hook Dx and draw FPS

It's not something new, it's just a bit of fun.

First, hook DX device, and then hook internal functions. Here, it is just the end mark function endscene of hook d3drender. Internally record FPS, and then create a d3dxfont object to show that FPS is drawn at the specified position on the screen.

Hook to d3d or the old method. Set the hook and set yourselfCodeInject to the remote process address space and hook the API in the DLL code.

Here we modify the IAT, and we can also use a method similar to deours (directly modify the function Execution Code, usually a jump command, as described in the previous post ). Then you can do something you want to do.

Here I modify IAT. Note that this method is not allProgramBecause DLL cannot be dynamically loaded.
