Windowed 将应用程序设置为标准的非全屏可移动窗口，其大小取决于应用程序分辨率。在此模式中，默认情况下可以调整窗口大小。要禁用此功能，请禁用 Resizable Window 设置。 Default Is Native Resolution 启用此选项可使游戏使用目标机器上使用的默认分辨率。如果 Fullscreen Mode 设置为 Windowed_，此选项不可用。| | Default Screen Width ||设置游戏画面的默认宽度（以像素为单位）。仅在 Fullscreen Mode 设置为 Windowed_ 时，此选项才可用。 Default Screen Height 设置游戏画面的默认高度（以像素为单位）。仅在 Fullscreen Mode 设置为 Windowed 时，此选项才可用。 Mac Retina Support 启用此选项可在 Mac 上启用高 DPI (Retina) 屏幕支持。Unity 默认情况下启用此功能。此功能可增强 Retina 显示屏上的项目显示效果，但在激活状态下会有点耗费资源。 Run In background Enable this option to have the game running in the background instead of pausing if the app loses focus. Resizable Window Enable this option to allow resizing of the desktop player window.
Note: If you disable this option, your application can’t use the Windowed Fullscreen Mode . Visible in Background 如果已将 Fullscreen Mode 设置为 _Windowed_，启用此选项可在背景中显示应用程序（在 Windows 中）。 Allow Fullscreen Switch 启用此选项可允许通过默认操作系统全屏按键在全屏模式和窗口模式之间切换。 Force Single Instance Enable this option to restrict desktop players to a single concurrent running instance. Supported Aspect Ratios 启用希望游戏启动时出现在分辨率对话框中的每个宽高比（只要用户的显示屏支持这些宽高比设置）。 Color Space Choose which color space Unity uses for rendering: Gamma or Linear. See the Linear rendering overview for an explanation of the difference between the two.
• Gamma : Gamma color space is typically used for calculating lighting on older hardware restricted to 8 bits per channel for the framebuffer format. Even though monitors today are digital, they might still take a gamma-encoded signal as input.
• Linear : Linear color space rendering gives more precise results. When you select to work in linear color space, the Editor defaults to using sRGB sampling. If your Textures are in linear color space, you need to work in linear color space and disable sRGB sampling for each Texture. Auto Graphics API for Windows Enable this option to use the best Graphics API on the Windows machine the game is running on. Disable it to add and remove supported Graphics APIs. Auto Graphics API for Mac Enable this option to use the best Graphics API on the Mac the game is running on. Disable it to add and remove supported Graphics APIs. Auto Graphics API for Linux Enable this option to use the best Graphics API on the Linux machine it runs on. Disable it to add and remove supported Graphics APIs. Color Gamut for Mac You can add or remove color gamuts for the Mac platform to use for rendering. Click the plus (+) icon to see a list of available gamuts. A color gamut defines a possible range of colors available for a given device (such as a monitor or screen). The sRGB gamut is the default (and required) gamut. Metal API Validation Enable this option when you need to debug Shader issues.
Note: Validation increases CPU usage, so use it only for debugging. Metal Write-Only Backbuffer Allow improved performance in non-default device orientation. This sets the frameBufferOnly flag on the back buffer, which prevents readback from the back buffer but enables some driver optimization. Memoryless Depth Choose when to use memoryless render textures . Memoryless render textures are temporarily stored in the on-tile memory when rendered, not in CPU or GPU memory. This reduces memory usage of your app but you cannot read or write to these render textures.
Note: Memoryless render textures are only supported on iOS, tvOS 10.0+ Metal and Vulkan. Render textures are read/write protected and stored in CPU or GPU memory on other platforms. Unused Never use memoryless framebuffer depth. Forced Always use memoryless framebuffer depth. Automatic Let Unity decide when to use memoryless framebuffer depth. Static Batching Enable this option to use Static batching. Dynamic Batching Enable this option to use Dynamic Batching on your build (enabled by default).
Note: Dynamic batching has no effect when a Scriptable Render Pipeline is active, so this setting is only visible when nothing is set in the Scriptable Render Pipeline Asset Graphics setting. Compute Skinning Enable this option to enable DX11/ES3 GPU compute skinning, freeing up CPU resources. Graphics Jobs Enable this option to instruct Unity to offload graphics tasks (render loops) to worker threads running on other CPU cores. This is intended to reduce the time spent in Camera.Render on the main thread, which is often a bottleneck. Lightmap Encoding Choose Normal Quality or High Quality to set the lightmap encoding. This setting affects the encoding scheme and compression format of the lightmaps. Lightmap Streaming Enable this option to load only the lightmap mip maps as needed to render the current game Cameras. This value applies to the lightmap textures as they are generated.
Note: To use this setting, you must enable the Texture Streaming Quality setting. Streaming Priority Set the lightmap mip map streaming priority to resolve resource conflicts. These values are applied to the light map textures as they are generated.
Positive numbers give higher priority. Valid values range from –128 to 127. Frame Timing Stats Enable this property to gather CPU and GPU frame time statistics. Use this together with the Dynamic Resolution camera setting to determine if your application is CPU or GPU bound. Use Display In HDR Mode (Windows Only) Enable this checkbox to make the game automatically switch to HDR mode output when it runs. This only works on displays that support this feature. If the display does not support HDR mode, the game runs in standard mode. Swap Chain Bit Depth Select the number of bits in each color channel for swap chain buffers. Only available if HDR Mode is enabled. Bit Depth 10 Unity will use the R10G10B10A2 buffer format and Rec2020 primaries with ST2084 PQ encoding. Bit Depth 16 Unity will use the R16G16B16A16 buffer format and Rec709 primaries with linear color (no encoding). Virtual Texturing Indicates whether to enable Virtual Texturing .
Note : The Unity Editor requires a restart for this setting to take effect. Shader precision model Controls the default precision of samplers used in shaders. See Shader data types and precision for more details. 360 Stereo Capture Indicates whether Unity can capture stereoscopic 360 images and videos. When enabled, Unity compiles additional shader variants to support 360 capture (currently only on Windows/OSX). When enabled, enable_360_capture keyword is added during the Stereo RenderCubemap call . Note that this keyword is not triggered outside the Stereo RenderCubemap function. For more information, see Stereo 360 Image and Video Capture . SRGB Write Mode Enable this option to allow Graphics.SetSRGBWrite() renderer to toggle the sRGB write mode during runtime. That is, if you want to temporarily turn off Linear-to-sRGB write color conversion, you can use this property to achieve that. Enabling this has a negative impact on performance on mobile tile-based GPUs; therefore, do NOT enable this for mobile. Number of swapchain buffers Set this option to 2 for double-buffering, or 3 for triple-buffering to use with Vulkan renderer. This setting may help with latency on some platforms, but in most cases you should not change this from the default value of 3. Double-buffering might have a negative impact on performance. Do not use this setting on Android. Acquire swapchain image late as possible If enabled, Vulkan delays acquiring the backbuffer until after it renders the frame to an offscreen image. Vulkan uses a staging image to achieve this. Enabling this setting causes an extra blit when presenting the backbuffer. This setting, in combination with double-buffering, can improve performance. However, it also can cause performance issues because the additional blit takes up bandwidth. Recycle command buffers Indicates whether to recycle or free CommandBuffers after Unity executes them. Bundle Identifier Enter the Bundle Identifier of your application. This appears as CFBundleIdentifier in the associated info.plist file. See the Apple developer documentation on CFBundleIdentifier to learn more.
To set this property, enable Override Default Bundle Identifier . Build Enter the build number for this version of your app. This appears as CFBundleVersion in the associated info.plist file. See the Apple developer documentation on CFBundleVersion to learn more. Enter the string corresponding to the app’s type. The App Store uses this string to determine the appropriate categorization for the app. By default, this is set to the game category, public.app-category.games . See the Apple developer documentation on LSApplicationCategoryType to see the list of category types available. Mac App Store Validation 通过启用此属性，可确保只有当应用程序包含来自 Mac App Store 的有效收据时才会运行。这样可以防止用户不在购买游戏的设备上而在另一台设备上运行游戏。仅当您已实施自己的收据验证时，才应禁用此设置。

Publishing to the Mac App Store

Use Player Log 属性允许将调试信息写入日志文件。这对于调查游戏问题很有用。但是，在为 Apple 的 Mac App Store 发布游戏时，需要禁用此功能，因为如果启用此功能，Apple 可能会拒绝您提交。有关日志文件的更多信息，请参阅 Unity 手册 日志文件 页面。

Use Mac App Store Validation 属性可启用 Mac App Store 的收据验证。如果启用此属性，则只有当游戏包含来自 Mac App Store 的有效收据时才会运行。将游戏提交给 Apple 以便在 App Store 上发布时，应使用此功能。这样可以防止用户不在购买游戏的计算机上而在另一台计算机上运行游戏。

请注意，此功能不实现任何强大的复制保护。特别需要说明的是，针对一个 Unity 游戏的任何潜在破解都将对所有其他 Unity 内容有效。因此，建议使用 Unity 的插件功能在此基础上实现您自己的收据验证代码。但是，由于 Apple 要求在显示屏幕设置对话框之前的最初阶段进行插件验证，因此您仍应启用此属性，以免 Apple 拒绝您的提交。

Scripting Define Symbols Set custom compilation flags. For more details, see the documentation on Platform dependent compilation . Additional Compiler Arguments Add entries to this list to pass additional arguments to the Roslyn compiler. Use one new entry for each additional argument.
To create a new entry, press the ‘+’ button. To remove an entry, press the ‘-’ button.
When you have added all desired arguments, click the Apply button to include your additional arguments in future compilations.The Revert button resets this list to the most recent applied state. Suppress Common Warnings Disable this setting to display the C# warnings CS0169 and CS0649 . Allow ‘unsafe’ Code 允许在预定义的程序集（例如， Assembly-CSharp.dll ）中编译 “不安全”的 C# 代码 。
对于程序集定义文件 ( .asmdef )，请单击其中一个 .asmdef 文件，并在出现的 Inspector 窗口中启用该选项。 Use Deterministic Compilation Disable this setting to prevent compilation with the -deterministic C# flag. With this setting enabled, compiled assemblies are byte-for-byte identical each time they are compiled.
For more information, see Microsoft’s deterministic compiler option documentation . Enable Roslyn Analyzers Disable this setting to compile user-written scripts without Roslyn analyzer DLLs that might be present in your project. Prebake Collision Meshes Enable this option to add collision data to Meshes at build time. Keep Loaded Shaders Alive When enabled, you cannot unload a shader. See Shader Loading for more information. Preloaded Assets Set an array of Assets for the player to load on startup.
To add new Assets, increase the value of the Size property, then set a reference to the Asset to load in the new Element box that appears. AOT compilation options Additional options for Ahead of Time (AOT) compilation. This helps optimize the size of the built iOS player . Strip Engine Code Enable this option if you want the Unity Linker tool to remove code for Unity Engine features that your Project doesn’t use. This setting is only available with the IL2CPP scripting backend.

Most apps don’t use every available DLL. This option strips out DLLs that your app doesn’t use to reduce the size of the built Player. If your app is using one or more classes that would normally be stripped out under your current settings, Unity displays a debug message when you try to build the app. Managed Stripping Level Choose how Unity strips unused managed (C#) code.The options are Disabled Low , Medium , and High .

When Unity builds your app, the Unity Linker process can strip unused code from the managed DLLs your Project uses. Stripping code can make the resulting executable significantly smaller, but can sometimes accidentally remove code that is in use. For more information about these options, see documentation on Managed code stripping .

For information about bytecode stripping with IL2CPP, see documentation on Managed bytecode stripping with IL2CPP . Vertex Compression Choose the channel that you want to set for compressing meshes under the vertex compression method, which by default, is set to Mixed. This affects all the meshes in your project. Typically, Vertex Compression is used to reduce the size of mesh data in memory, reduce file size, and improve GPU performance. For information on how to configure vertex compression and limitations of this setting, see [compressing meshes]. Optimize Mesh Data Selecting this option enables stripping of unused vertex attributes from the mesh used in a build.
This reduces the amount of data in the mesh, which might help reduce build size, loading times, and runtime memory usage. However, you must remember to not change material or shader settings at runtime, if you have this setting enabled. See PlayerSettings.stripUnusedMeshComponents for more information. Texture MipMap Stripping Enable this option to enable mipmap stripping for all platforms, which strips unused mipmaps from Textures at build time. Unity determines unused mipmaps by comparing the value of the mipmap against the Quality Settings for the current platform. If a mipmap value is excluded from every Quality Setting for the current platform, then Unity strips those mipmaps from the build at build time. If QualitySettings.masterTextureLimit is set to a mipmap value that has been stripped, Unity will set the value to the closest mipmap value that has not been stripped. Clamp BlendShapes (Deprecated) Enable the option to clamp the range of blend shape weights in SkinnedMeshRenderers . Upload Cleared Texture Data This is a legacy feature and currently not needed because it uses up the bandwidth. By default, this is enabled for debugging purposes. Enabling this setting clears the initial data and automatically uploads the Texture from script to the video memory.
