How does reshade get (inject?) the files into the

game?

Can i simply copy my .ini and my .dll files that reshade created into the game folder to another computer to the same folder the game (squad) is and i have reshade there working?

So the reshade.exe only copy the dll to the right folder, and game looks in the folder , see dll and execute it?

Or is it so that there is an active injection in the game exe? in that case i wonder how its done, cause when there is a game update with new exe i dont had to run reshade.exe again, game is still working.
