Abstract: Methods and devices for testing graphics hardware may include reading content of a selected capture file from a plurality of capture files. The methods and devices may include transferring content from the selected capture file to an emulator memory of an emulator separate from the computer device. The methods and devices may include executing at least one pseudo central processing unit (pseudo CPU) operation to coordinate the execution of work on a graphics processing unit (GPU) of the emulator using the content from the selected capture file to test the GPU. The methods and devices may include receiving and store rendered image content from the emulator when the work is completed.
