#pragma target gl4.1 // Desktop OpenGL 4.1, SM 4.0 + tessellation to match MacOSX 10.9 capabilities.

#pragma target 4.0 // OpenGL ES 3.1, desktop OpenGL 3.x, DX Shader Model 4.0.

When using the existing #pragma targets, they map to following GL levels: Indirect draw (Graphics.DrawProcedural and Graphics.DrawProceduralIndirect).Compute shaders (as well as ComputeBuffers and “random write” render textures).The new OpenGL back-end introduces many new features (previously mostly DX11/GLES3 only): This target level requires at least OpenGL 4.1 or DirectX 11.0 Shader Level 5 on desktop, or OpenGL ES 3.1 + Android Extension Pack on mobiles. Therefore a new shader target level is introduced: #pragma target gl4.1. This means that all shaders that are configured to target Shader Level 5.0 (with #pragma target 50) will fail to load on OS X. However, as Apple restricts the OpenGL version on OS X desktop to 4.1 at most, it does not support all DirectX 11 features (such as Unordered Access Views or Compute Shaders). The macOS OpenGL backend for the Editor and Standalone supports OpenGL 3.x and 4.x features such as tessellation and geometry shaders A program that runs on the GPU. Windows with NVIDIA since 2006 (GeForce 8), AMD since 2006 (Radeon HD 2000), Intel since 2012 (HD 4000 / IvyBridge) (OpenGL 3.2 to OpenGL 4.5)

OpenGL Core has the following minimum requirements: For more details, see Graphics API support.

Disable the Auto Graphics API for Windows property, and choose OpenGLCore from the list. To set OpenGL Core as your default Graphics API in the Editor or Standalone Player, go to the Player settings (menu: Edit > Project Settings, then select the Player category), and navigate to Other Settings. This scales from OpenGL 3.2 to OpenGL 4.5, depending on the OpenGL driver support. OpenGL Core is a back-end capable of supporting the latest OpenGL features on Windows, MacOS X and Linux.
