SystemInfo.maxGraphicsBufferSize

描述

图形缓冲区的最大大小（GraphicsBuffer、ComputeBuffer、顶点/索引缓冲区等），以字节为单位（只读）。

Any GPU buffer (GraphicsBuffer, ComputeBuffer or a vertex/index buffer used by a Mesh) can not be larger than this amount of bytes.

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        // prints maximum graphics buffer size, in megabytes
        var maxSizeMb = SystemInfo.maxGraphicsBufferSize / 1024 / 1024;
        Debug.Log($"Maximum graphics buffer size is {maxSizeMb} MB");
    }
}
