 We ran the first 1500 frames of [Tobu Tobu Girl](https://tangramgames.dk/tobutobugirl/) in "headless" mode (i.e. without UI) for 10 times each and calculated the average FPS. The error bars represent the standard deviation. See [`benchmark.md`](benchmark.md) for details about the environment / commands used for the benchmark.
