Abstract: In one aspect, a graphics processing unit (GPU) data sniffing method includes the step of providing a video game software comprising a set of graphics data of a video game. The method includes the step of communicating the set of graphics data to a graphics library using an application programming interface (API) call to the graphics library. The graphics library includes at least one application API interface. The method includes the step of providing a sniffing module. The sniffing module intercepts the set of graphics data before the set of graphics data reaches the GPU. The sniffing module copies the set of graphics data to create a copy of the graphics data. The sniffing module forwards the copy of the graphics data to the graphics library for rendering to a receiving entity.
