# Top runs: * **Highest FPS**: `Megabonk OGL` with a slightly higher average FPS than the Vulkan runs, thereby providing the best frame rate performance. * **Smoothest FPS**: `Megabonk VK Wayland` has the lowest standard deviation in FPS, indicating the most stable frame rate. * **Best overall**: `Megabonk VK Wayland`, as it offers a good balance of high FPS with smooth performance, and the GPU load and power metrics are well-managed. # Issues: * The `Megabonk OGL` run demonstrates a noticeable increase in frame time variability compared to the Vulkan runs, which indicates less smooth frame rendering. * Under Vulkan on Wayland, the GPU power draw is slightly higher compared to the non-Wayland Vulkan, even though GPU load is lesser. * The `Megabonk OGL` run also shows elevated GPU temperatures compared to both Vulkan runs, suggesting higher thermal output or less efficient cooling. # Summary This benchmark compares the performance of the Megabonk application using the `Vulkan` API on both `Wayland` and traditional setups against the `OpenGL` API. The `OpenGL` setup led in frame rate but at the cost of increased frame time variability and higher GPU temperatures, suggesting less consistency and efficiency. Meanwhile, the `Wayland` enabled `Vulkan` run achieved the smoothest overall performance with well-balanced GPU usage and power draw, making it the best choice for both performance and stability. These insights highlight the potential for Vulkan with Wayland to optimize rendering efficiency in this context compared to traditional OpenGL.
