Generates intermediate graphics commands via the main thread. The render thread converts them into low-level platform API graphics commands.
In this mode, the main thread processes the application's high-level code through an internal class GfxDeviceClient that issues an intermediate representation of all the required graphics commands, and stores them in a buffer shared with the render thread.
At the same time, the render thread keeps reading from that shared buffer through an internal class GfxDeviceWorker . When the render thread reads a new intermediate graphics command, it forwards it to a separate internal class GfxDevice[Platform] that converts them into the platform's low-level graphics API commands.
On some platforms you can test this mode by passing the command line argument -force-gfx-mt to an application built with BuildSettings option BuildOptions.Development.
