Unity 检测手机性能，区分高中低端机型（URP）-Toy模板网

这篇具有很好参考价值的文章主要介绍了Unity 检测手机性能，区分高中低端机型（URP）。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

有兴趣可查看之前写的标准渲染管线的版本

适配了URP渲染管线，并增加了抛弃第一次采样的数据（涉及Shader编译会影响采样数据）

可设置隔帧采样不影响游戏运行

一般在游戏启动进登录界面时可以开始，Camera设置为场景相机

unity 机型分档位的规则,unity,游戏引擎,性能评分,机型适配,c#

注意：

Maximum Sample Counter和Draw Times Per Batch不宜设置太高，否则可能出现在UPR或者UWA报告中看到DrawCall和面数超高的情况

Mesh最好在500面左右
