Improving Graphics Interactivity - It's All in the Timing

Explore the intricacies of improving graphics interactivity in this Linux Plumbers Conference talk. Delve into the challenges of meeting real-time requirements for interactive applications, from games to virtual reality environments. Learn about the importance of precise timing in displaying information and the inconsistencies in the current graphics stack. Discover proposed solutions throughout the system, including kernel changes, composited window system improvements, and additions to rendering APIs like Vulkan. Witness demonstrations of poor display timing effects and gain insights into creating a smoother animation experience for users. Examine topics such as frame timing, OpenGL and Vulkan loops, composited display methods, and the Linux Flip API. Gain a comprehensive understanding of the complexities involved in enhancing graphics performance and interactivity in Linux systems.
