 ===== Enable graphics acceleration in Chromium ===== ===== Enable graphics acceleration in Chromium =====
 +
 +In Chromium you can open the page **%%chrome://gpu%%** and check the **Graphics Feature Status**, you should read:
 +
 +^ Canvas  | Hardware accelerated  |
 +^ Canvas out-of-process rasterization  | Enabled  |
 +^ Direct Rendering Display Compositor  | Disabled  |
 +^ Compositing  | Hardware accelerated  |
 +^ Multiple Raster Threads  | Enabled  |
 +^ OpenGL  | Enabled  |
 +^ Rasterization  | Hardware accelerated on all pages  |
 +^ Raw Draw  | Enabled  |
 +^ Video Decode  | Hardware accelerated  |
 +^ Video Encode  | Software only. Hardware acceleration disabled  |
 +^ Vulkan  | Disabled  |
 +^ WebGL  | Hardware accelerated  |
 +^ WebGL2  | Hardware accelerated  |
 +^ WebGPU  | Disabled  |
 +
 +Probably something is disabled, because of Chromium defaults. In that case you have to open the page **%%chrome://flags%%**, then search and set the following flags:
 +
 +^ Override software rendering list  | Overrides the built-in software rendering list and enables GPU-acceleration on unsupported system configurations.  |
 +^ Enable raw draw  | When enabled, web content will be rastered on output surface directly.  |
 +^ GPU rasterization  | Use GPU to rasterize web content.  |
 +^ Out-of-process rasterization  | FIXME Does this exists?  |
 +^ Out-of-process 2D canvas rasterization  | The rasterization of 2d canvas contents is performed in the GPU process.  |
 +^ Accelerated 2D canvas  | Enables the use of the GPU to perform 2d canvas rendering instead of using software rendering.  |
 +^ Hardware-accelerated video decode  | FIXME Does this exists?  |
