有些项目需要根据设备性能自动修改Quality的设置，如何判断设备性能已经在上一篇中讲过了。这一篇把判断设备性能和设置质量放到一起去，形成静态类工具。
调用方式如下：
using UnityEngine;
public class Test : MonoBehaviour
{
void Start()
{
Debug.Log(DevicePerformanceUtil.GetDevicePerformanceLevel());
//根据设备配置自动设置质量
DevicePerformanceUtil.ModifySettingsBasedOnPerformance();
//手动设置质量
//DevicePerformanceUtil.SetQualitySettings(QualityLevel.Low);
}
}
工具脚本：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
/// <summary>
/// 硬件设备性能适配工具
/// </summary>
public static class DevicePerformanceUtil
{
/// <summary>
/// 获取设备性能评级
/// </summary>
/// <returns>性能评级</returns>
public static DevicePerformanceLevel GetDevicePerformanceLevel()
{
if (SystemInfo.graphicsDeviceVendorID == 32902)
{
//集显
return DevicePerformanceLevel.Low;
}
else //NVIDIA系列显卡（N卡）和AMD系列显卡
{
//根据目前硬件配置三个平台设置了不一样的评判标准（仅个人意见）
//CPU核心数
#if UNITY_EDITOR || UNITY_STANDALONE_WIN
if (SystemInfo.processorCount <= 2)
#elif UNITY_STANDALONE_OSX || UNITY_IPHONE
if (SystemInfo.processorCount < 2)
#elif UNITY_ANDROID
if (SystemInfo.processorCount <= 4)
#endif
{
//CPU核心数<=2判定为低端
return DevicePerformanceLevel.Low;
}
else
{
//显存
int graphicsMemorySize = SystemInfo.graphicsMemorySize;
//内存
int systemMemorySize = SystemInfo.systemMemorySize;
#if UNITY_EDITOR || UNITY_STANDALONE_WIN
if (graphicsMemorySize >= 4000 && systemMemorySize >= 8000)
return DevicePerformanceLevel.High;
else if (graphicsMemorySize >= 2000 && systemMemorySize >= 4000)
return DevicePerformanceLevel.Mid;
else
return DevicePerformanceLevel.Low;
#elif UNITY_STANDALONE_OSX || UNITY_IPHONE
if (graphicsMemorySize >= 4000 && systemMemorySize >= 8000)
return DevicePerformanceLevel.High;
else if (graphicsMemorySize >= 2000 && systemMemorySize >= 4000)
return DevicePerformanceLevel.Mid;
else
return DevicePerformanceLevel.Low;
#elif UNITY_ANDROID
if (graphicsMemorySize >= 6000 && systemMemorySize >= 8000)
return DevicePerformanceLevel.High;
else if (graphicsMemorySize >= 2000 && systemMemorySize >= 4000)
return DevicePerformanceLevel.Mid;
else
return DevicePerformanceLevel.Low;
#endif
}
