I’ve been looking at our performance recently and I’ve noticed that SystemInfo.graphicsMultiThreaded is always false and SystemInfo.renderingThreadingMode is LegacyJobified in a Player build but in the editor it is On and MultiThreaded
What values are you setting for PlayerSettings.MTRendering, PlayerSettings.graphicsJobs and PlayerSettings.graphicsJobsMode? The combination of these settings (plus build target capabilities) define which mode is effectively going to be used.
