通过新的任天堂Switch模式确定CPU，GPU和温度状态 Writing by JP.Lee Nintendo Switch是任天堂开发的小型游戏机。 我认为，作为纯游戏用途的Nintendo Switch卖得好的原因是比智能手机小，易于操作，并且还支持Wi-Fi，因此可以多重博弈。 任天堂 Switch的配置和规格如下。 可以说，现有的iphone11顶级版本或者iPad Pro第三代的性能与任天堂Switch相似。 但是我个人认为，任天堂Switch具有专注于游戏性的内部设计结构，所以更优秀一点。 此外，安装在扩展坞的时候和手持式状态的优化系统也非常优秀。 * CPU : NVIDIA TEGRA X1+ T210B01 * GPU : NVIDIA GM20B * RAM […]

BuildConfiguration Download bUseUnityBuildWhether to unify C++ code into larger files for faster compilation. bForceUnityBuildWhether to force C++ source files to be combined into larger files for faster compilation. bUseAdaptiveUnityBuildUse a heuristic to determine which files are currently being iterated on and exclude them from unity blobs, result in faster incremental compile times. The current implementation uses the read-only flag to […]
유니티 HDRP 에서 제공하고 있는 BentNormal 을 이용한 Ambient Occlusion 처리와 Reflection Occlusion 부분을 Custom URP 로 이식 해 보는 과정이다. 프로젝트에 따라 HDRP 의 특정 함수부는 활용이 가능하다고 생각한다. 예로 들어서 HDRP 에서만 작동 되는 Spherical Reflection Probe 같은 것들이다.모바일 게임개발 프로젝트라고 해도 특정 조건과 상황에 따라 HDRP 의 기능을 이식해서 활용 할 수 있는 하드웨어 환경이 되었기 때문이데 […]

在GPU避免分支的方法Unity TechnologiesOrigianl Authored by Brandon Fogerty(XR Graphics Engineer at Unity Technologies.) Additional Organized by JP.Lee(李正彪）leegoonz@163.com概要这边来稿文章中，希望了解如何编写GPU着色器友好型代码，以避免和分支相关的性能费用。“分支”有着什么意义？使用明确的 if / then随时都可以产生分支。编译器遇到条件会作出命令。GPU可去的地方有两处。因此需要决定要使用哪种代码路径。以下示例展示了在汇编GPU里面运行的示例。运算变量设置为幻数7，则添加该数字。否则的话要减掉。 为什么要避免分支？为了增加CPU使用率，大多数计算机都尝试在管线上执行尽可能多的任务。汇编指令按顺序执行，CPU会尝试在尽可能多的CPU内核上执行尽可能多的指令。举个简单的例子。想象一下，在Twilight Zone内，我们就是世界上最高效的程序员! 用两行代码写了电子游戏！ CPU会尽可能在每一个CPU内核上各执行一个，共计两个光荣的指令。这是计算机能够更有效的运行代码。 但是在分支时，计算机可能会花时间准备未运行的代码结果。从结论上看处理器时间被浪费，影响了游戏或应用程序的应答能力。CPU 侧分枝误诊通常会导致周期遗漏超过40次。– Charles Sanglimsuwan (集成开发人员相关工程师)运气不错，最新的CPU处理器速度惊人，实际分支预测出色，因此分支错失几乎不会有问题。但是GPU仍然存在性能问题。 GPU尝试并行解决大量计算，因此大部分GPU不支持分支预测GPU为什么会发生性能问题？GPU为生成美丽的图像，喜欢并行进行很多工作！GPU为进行多种固有的结果计算，进行了精心设计，解决了通过单一滤镜（例如：着色器程序）实施的多种输入和相关的问题。这就是渲染经常使用GPU(Graphics processor units)的原因。通过几个Shader程序运行位置，法线，贴图坐标等具有不同属性的固有顶点，该Shader程序输出在画面上表现的大量固有像素颜色。举个例子，显示器是1080 […]
