If the host machine doesn't support\naccelerated graphics or the Android version is\nAndroid 10 or lower, guest-side rendering (for example,\nUI and video playback) in your Cuttlefish device is handled by SwiftShader.\nSwiftShader is a software implementation of the OpenGL and Vulkan APIs. Because\nSwiftShader is a software implementation, it provides a universally accessible\nrendering solution for Cuttlefish capable of running on any host machine.\n\nHowever, using SwiftShader isn't as performant as a normal device. Rendering is\na parallel problem that can be massively parallelized, as pixel\nvalues can be computed independently. Graphics processing units (GPUs) are\nhardware units that address this problem by accelerating rendering.\n\nRequirements\n------------\n\nAccelerated graphics mode requires that the host have:\n\n- EGL capable driver supporting the `GL_KHR_surfaceless_context` extension\n- OpenGL ES capable driver\n- Vulkan capable driver\n\nUse accelerated graphics modes\n------------------------------\n\n### GfxStream\n\nTo use the GfxStream accelerated graphics mode, launch your local Cuttlefish\ndevice with the `--gpu_mode=gfxstream` flag. Using this mode, OpenGL and Vulkan\nAPI calls are forwarded directly to the host. \n\n```\nlaunch_cvd --gpu_mode=gfxstream\n```\n\n### Virgl\n\nTo use the Virgl accelerated graphics mode, launch your local Cuttlefish device\nwith the `--gpu_mode=drm_virgl` flag. \n\n```\nlaunch_cvd --gpu_mode=drm_virgl\n```\n\nWhen using the Virgl accelerated graphics mode, OpenGL API calls are translated\ninto an intermediate representation (see\n[Gallium3D](https://www.freedesktop.org/wiki/Software/gallium/)). The\nintermediate representation is communicated to the host and the\n[virglrenderer](https://gitlab.freedesktop.org/virgl/virglrenderer) library on\nthe host translates the intermediate representation back to OpenGL API calls.\n| **Note:** Vulkan isn't supported."]]
