SystemInfo.graphicsShaderLevel

説明

グラフィックデバイスのシェーダーの性能レベル（読み取り専用）

This is approximate "shader capability" level of the graphics device, expressed in DirectX shader model terms. Possible values are:

50 Shader Model 5.0 (DX11.0)
41 Shader Model 4.1 (DX10.1)
40 Shader Model 4.0 (DX10.0)
30 Shader Model 3.0
20 Shader Model 2.x.

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        // Check for shader model 3.0 or better support
        if (SystemInfo.graphicsShaderLevel >= 30)
            print("Woohoo, decent shaders supported!");
    }
}
