Post-Render Warp with Late Input Sampling Improves Aiming Under High Latency Conditions, Joohwan Kim, Pyarelal Knowles, Josef Spjut, Ben Boudaoud and Morgan McGuire, High Performance Graphics, 2020;

End-to-end latency in remote-rendering systems can reduce user task performance. This notably includes aiming tasks on game streaming services, which are presently below the standards of competitive first-person desktop gaming. We evaluate the latency-induced penalty on task completion time in a controlled environment and show that it can be significantly mitigated by adopting and modifying image and simulation-warping techniques from virtual reality, eliminating up to 80% of the penalty from 80 ms of added latency. This has potential to enable remote rendering for esports and increase the effectiveness of remote-rendered content creation and robotic teleoperation. We provide full experimental methodology, analysis, implementation details, and source code.
