1.修改渲染分辨率
1).Quality等级的预设 a.打开Edit->Project Settings->Quality b.新建High/Medium/Low三个等级,分别设置分辨率缩放(High=1.0、Medium=0.8、Low=0.65)c.记住每个等级的"名称",比如High对应Quality面板里的High,需和代码里的字符串一致2).编写运行时检测设备性能并切换等级的代码usingUnityEngine;usingSystem.Collections;publicclassQualityLevelAutoSwitch:MonoBehaviour{// 游戏启动时优先执行（早于Start）privateIEnumeratorStart(){// 等待1帧，确保系统信息加载完成（避免获取不到GPU信息）yieldreturnnull;// 1. 检测设备性能，返回推荐的Quality等级名称stringrecommendedQuality=DetectDevicePerformance();// 2. 切换到推荐的Quality等级SetQualityLevel(recommendedQuality);// 可选：打印日志，方便调试Debug.Log($"设备性能检测完成，当前Quality等级：{QualitySettings.names[QualitySettings.GetQualityLevel()]}");Debug.Log($"当前分辨率缩放比例：{QualitySettings.resolutionScalingFixedDPIFactor}");}/// <summary>/// 检测设备性能，返回推荐的Quality等级名称（High/Medium/Low）/// </summary>privatestringDetectDevicePerformance(){// 核心检测维度（可根据项目需求调整权重）// 维度1：GPU内存（最核心的性能指标，单位：MB）intgpuMemory=SystemInfo.graphicsMemorySize;// 维度2：处理器核心数intcpuCores=SystemInfo.processorCount;// 维度3：设备是否为移动平台（移动端默认降一档）boolisMobile=Application.isMobilePlatform;// 检测逻辑（可根据项目需求自定义）if(isMobile){// 移动端分级if(gpuMemory>=8192)// 8G及以上GPU内存（高端机：骁龙8Gen3、A17等）return"High";elseif(gpuMemory>=4096)// 4G~8G（中端机：骁龙7+ Gen2、天玑8200等）return"Medium";else// 4G以下（低端机）return"Low";}else{// PC/主机分级if(gpuMemory>=16384)// 16G及以上GPU内存（高端显卡：RTX4070、RX7800XT等）return"High";elseif(gpuMemory>=8192)// 8G~16G（中端显卡：RTX3060、RX6600等）return"Medium";else// 8G以下（低配PC）return"Low";}}/// <summary>/// 切换到指定的Quality等级/// </summary>privatevoidSetQualityLevel(stringqualityName){// 遍历所有Quality等级，找到匹配的名称for(inti=0;i<QualitySettings.names.Length;i++){if(QualitySettings.names[i]==qualityName){QualitySettings.SetQualityLevel(i,true);// true=立即应用break;}}// 兜底：如果没找到匹配的等级，默认设为Mediumif(QualitySettings.names[QualitySettings.GetQualityLevel()]!=qualityName){QualitySettings.SetQualityLevel(QualitySettings.names.Length-2,true);Debug.LogWarning($"未找到{qualityName}等级，默认切换为Medium");}}// 可选：给玩家手动切换等级的接口（比如设置界面的按钮调用）publicvoidManualSwitchQuality(stringqualityName){SetQualityLevel(qualityName);}}
