使用DLSS和FSR升级

警告

The feature is still EXPERIMENTAL.该功能仍然是实验。

UNIGINE provides support for two advanced upscaling technologies: NVIDIA DLSS (Deep Learning Super Sampling) and AMD FSR 2 (FidelityFX Super Resolution 2). These technologies enable upscaling on a wide range of devices from different manufacturers.UNIGINE支持两种高级升频技术：NVIDIA DLSS(Deep Learning Super Sampling)和AMD FSR 2(FidelityFX Super Resolution 2)。 这些技术可以在来自不同制造商的各种设备上进行升级。

注意

UNIGINE provides support for DLSS 3 and FSR 2.2.UNIGINE提供了对DLSS 3和FSR 2.2的支持。

These upscaling technologies are used to render high-resolution images based on the lower resolution source. If both upscalers are available, you can choose between them, or you can turn off upscaling at all. We suggest using the DLSS technology as it produces high-quality results with fewer visual artifacts.这些升频技术用于基于较低分辨率源呈现高分辨率图像。 如果两个升频都可用，则可以在它们之间进行选择，也可以完全关闭升频。 我们建议使用DLSS技术，因为它可以产生高质量的结果，减少视觉伪影。

注意

DLSS is not available out-of-the-box and requires additional configuration of your UNIGINE project.DLSS 无法开箱即用，需要对 UNIGINE 项目进行额外配置。

注意

The TAA effect is automatically disabled for the final image rendering when the DLSS or FSR 2 upscaling is applied.当应用DLSS或FSR2升频时，将自动禁用最终图像渲染的TAA效果。

The DLSS and FSR 2 upscalers have specific requirements and compatibility restrictions determining whether the application supports these features.DLSS和FSR2升频器具有特定要求和兼容性限制，可确定应用程序是否支持这些功能。

The upscalers are initialized on render initialization. To verify whether they are supported and initialized after application startup, you can do one of the following:升频器在渲染初始化时初始化。 要验证它们是否受支持并在应用程序启动后初始化，可以执行以下操作之一:

• Check the Render section of the console output.检查控制台输出的Render部分。
• Run the dlss_info and/or fsr_info console commands.运行dlss_info和/或fsr_info控制台命令。

For example, the Render section may provide the following information:例如，Render部分可以提供以下信息:

---- Render ----
DLSS is supported
DLSS Streamline version: 2.4.0
DLSS NGX version: 3.7.0
FSR is supported
FSR Version: 2.2.2
FSR Max Contexts: 8
FSR RAM Scratch Size: 10 MB

If the upscaler is not supported, a corresponding message will be displayed in the console.如果不支持upscaler，则控制台中将显示相应的消息。

DLSS

DLSS#

For proper work, DLSS must meet the following requirements:对于正确的工作，DLSS必须满足以下要求:

• Platforms: Windows平台：Windows
• Graphic API: DirectX 12图形API:DirectX12
• Hardware: any GeForce RTX GPU and RTX 40 Series GPU.硬件：任何GeForce RTX GPU和RTX40系列GPU。
• Driver: 522.25 version or newer.驱动程序：522.25版本或更高版本。

For example, if you run the application with a GPU that is not listed, you will receive the following message in the console:例如，如果您使用未列出的GPU运行应用程序，您将在控制台中收到以下消息:

源代码

DLSS is not supported
Not an Nvidia GPU

注意

In addition, you can receive messages on missing libraries, as DLSS requires additional configuration of your UNIGINE project.此外，您还可以接收有关缺少库的消息，因为 DLSS 需要对您的 UNIGINE 项目进行其他配置。

FSR 2

FSR2#

FSR is not implemented, FSR is currently available only for DX12

For DLSS technology to work properly with UNIGINE, additional environment configuration is required.为了使DLSS技术与UNIGINE一起正常工作，需要额外的环境配置。

To use FSR 2 for the scene, enable it in one of the following ways and specify settings:要在场景中使用FSR2，请通过以下方式之一启用它并指定设置:

• Via the UnigineEditor interface:通过UnigineEditor接口:

  

• Using the render_upscale_mode console command:使用render_upscale_mode控制台命令:

  源代码

  render_upscale_mode 1

Depending on the current upscale mode, the set of settings differs. Please refer to the Upscalers article.根据当前的高档模式，设置集不同。 请参阅Upscalers文章。

By default, upscaling is applied before all post-processing effects are rendered. However, you can choose to apply upscaling after rendering the post-process effects.默认情况下，在渲染所有后处理效果之前应用放大。 但是，您可以选择在渲染后处理效果之后应用放大。

It can be done via the console using the render_upscale_post command or in UnigineEditor by toggling the Upscale After Post Effects parameter.它可以通过控制台使用render_upscale_post命令或在UnigineEditor中通过切换Upscale After Post Effects参数来完成。

A context is a single call per upscaling operation. The number of contexts that can be upscaled with FSR 2 is limited and can defined by the fsr_max_contexts console command. The recommended number of contexts is 8. Specifying the number of contexts is necessary when rendering into multiple viewports: the number of the viewports must correspond to the number of contexts.一个上下文是每个扩展操作的单个调用。 可以使用FSR2升频的上下文的数量是有限的，可以由fsr_max_contexts控制台命令定义。 推荐的上下文数为8。 在呈现到多个视口时，指定上下文的数量是必要的：视口的数量必须与上下文的数量相对应。
