Unity forum graphics12/23/2023 This is controlled by the Shader Compilation Target level.įor graphics API specific information, see documentation on Metal, DirectX and OpenGL. Tessellation and geometry shaders are only supported by a subset of graphics APIs. More info See in Glossary language semantics, see Platform-specific rendering differences. If the default API isn’t supported by the specific platform, Unity uses the next API in the Auto Graphics API list.įor information on how graphics rendering behaves between the platforms and Shader A program that runs on the GPU. The graphics API at the top of the Auto Graphics API list is the default API. Adding OpenGLCore to the Graphics APIs for Windows list To override the default graphics APIs and use an alternate graphics API for the Editor and Player, uncheck the relevant Auto Graphics API, click the plus (+) button and choose the graphics API from the drop-down menu. It is strongly recommended you read the following thread to learn the profiler: Other - Guide to unity profiler: HDRP version (And how to read profiler data) - Unity Forum - GPU: VOLUMETRICS. So, for example, to see how your application runs on OpenGL in the Editor, move OpenGLCore to the top of the list and the Editor switches to use OpenGL rendering. I have got a deformable triangular meshes such as cloths or skinned avatars held in Compute Buffers and entirely simulated on GPU. When Auto Graphics API for a platform is not checked, the Editor uses the first API in the list. When Auto Graphics API for a platform is checked, the Player build includes a set of built-in graphics APIs and uses the appropriate one at run time to produce a best case scenario. Navigate to Other Settings and make sure Auto Graphics API is checked: Using the default graphics APIs Open the Player settings (menu: Edit > Project Settings, then select the Player category). Failure to use the profiler first means youre just guessing, making a mess of your code for no good reason. Always start by using the profiler: Window -> Analysis -> Profiler. Unity uses a built-in set of graphics APIs, or the graphics APIs that you select in the Editor. If you dont have a problem, DO NOT OPTIMIZE If you DO have a problem, there is only ONE way to find out. Unity supports DirectX, Metal, OpenGL, and Vulkan graphics APIs, depending on the availability of the API on a particular platform.
