Paper Abstract:	A large portion of recent personal computers are equipped with both integrated and discrete GPUs. However, most of the time these two GPUs are not utilized concurrently in the same application. This paper provides an exploration into utilizing integrated plus discrete GPUs to improve real-time rendering performance with Vulkan API. Specifically, our approach includes offloading asynchronous computation workload from the discrete GPU to the integrated GPU, and multi-threading and render graphs are adopted to saturate GPUs utilization. Through benchmarking, we validate that our approach can speed up the overall performance by up to 4% with the utilization of combinations like Intel UHD 630 plus NVIDIA RTX 2070. Our results reveal that with tools like Vulkan, such heterogeneous-GPU system is exploitable.
