A method of generating a high-resolution image frame for a state of a video game within a 2D or 3D environment is disclosed. A low-resolution data map of a virtual camera frustum view of the 2D or 3D environment for the state is determined. The data map is of a data type. A high-resolution output data map of the data type is generated from the low-resolution data map. The generating of the high-resolution output data map includes training a neural network. The training includes associating a low-resolution data map of the data type with a high-resolution data map of the data type within the 2D or 3D environment. A high-resolution image of the frustum view is generated from the high-resolution output data map. The generated high-resolution image is displayed on a display device.
