ArcGIS Pro can use several\nversions of DirectX and OpenGL. The default value is DirectX, and in most\ncases, this is the optimal setting. <\/p>\n\n\n\n<p>Whichever option you choose, ArcGIS Pro will determine whether your\ngraphics card supports the capabilities required for any version of the DirectX\nor OpenGL rendering engine. It will automatically choose the adequate version\nof DirectX or OpenGL for your graphics card, or return to the slowest option\n(rendering software) if no graphics card is available to support the requested\nfunctionality. <\/p>\n\n\n\n<p>In few cases, a particular model or driver on a graphics card may\nperform better with OpenGL rendering rather than DirectX. This option (OpenGl)\nis provided as a way to evaluate whether OpenGL works best for your particular\ngraphics hardware or for troubleshooting purposes. <\/p>\n\n\n\n<p>Rendering quality allows you to optimize 3D rendering based on speed or\nquality. Depending on the capabilities of your computer and its graphics card,\nas well as the number and resolution of elevation sources and layer properties,\nincreased detail may result in decreased performance. If you experience\nperformance issues, reducing this setting will reduce the amount of data\ndisplayed without having to modify the card and layer properties. This is\nuseful when a high-quality 3D scene is displayed on a computer with\nspecifications below optimum, or when you run a virtual machine instance with\nlimited resources. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Since version 10.2, you have an option in ArcMap that significantly speeds up the display of rasters.
