COMPUTING SYSTEM AND METHODS OF OPERATING THE COMPUTING SYSTEM

A method of operating a computing system includes receiving, by a GPU driver included in a CPU of the computing system, a plurality of commands associated with a plurality of rendering targets included in a frame buffer of the computing system, storing the plurality of commands in a command buffer included in the GPU driver, setting, by a command manager included in the GPU driver, at least one unused rendering target among the plurality of rendering targets to a delayed submission mode, and selectively deleting, by the command manager, a command associated with the at least one unused rendering target set to the delayed submission mode from the command buffer based on whether the command includes an instruction to invalidate a rendering result associated with the at least one unused rendering target.
