Intel® XeSS Sample Applications

This directory contains basic sample applications demonstrating integration of Intel® XeSS technologies.

Contents:

System Requirements

  • Windows 10/11
  • Compatible GPU
  • Visual Studio 2019 or newer
  • CMake 3.20 or newer

XeSS-SR DX12 Basic Sample

Demonstrates basic XeSS-SR integration with DirectX 12.

Windows Build Steps

Run a 'Developer Command Prompt for Visual Studio 2019', then execute the following commands:

cmake -S . -B build
cmake --build build --config Debug --target ALL_BUILD

Command Line Options

  • -gpu_id value: Selects GPU by ID.

Keyboard Shortcuts

  • 1: Display input color.
  • 2: Display input velocity.
  • 3: Display output.
  • space: Pause animation.

XeSS-SR Vulkan Basic Sample

Demonstrates basic XeSS-SR integration with Vulkan.

Windows Build Steps

Install the Vulkan SDK from https://www.lunarg.com/vulkan-sdk/.

The sample requires the "glm" library source code to be unpacked into the basic_sample_vk/glm directory. Use the following commands to download and unpack the glm library:

powershell -command "Invoke-WebRequest https://github.com/g-truc/glm/releases/download/1.0.1/glm-1.0.1-light.zip -OutFile glm-1.0.1-light.zip"
powershell -command "Expand-Archive -Path glm-1.0.1-light.zip -DestinationPath ."

Run a 'Developer Command Prompt for Visual Studio 2019', then execute the following commands:

cmake -S . -B build
cmake --build build --config Debug --target ALL_BUILD

Command Line Options

  • -gpu_id value: Selects GPU by ID.

Keyboard Shortcuts

  • 1: Display input color.
  • 2: Display input velocity.
  • 3: Display output.
  • space: Pause animation.

XeSS-SR DX11 Basic Sample

Demonstrates basic XeSS-SR integration with DirectX 11.

Windows Build Steps

Run a 'Developer Command Prompt for Visual Studio 2019', then execute the following commands:

cmake -S . -B build
cmake --build build --config Debug --target ALL_BUILD

Command Line Options

  • -gpu_id value: Selects GPU by ID.

Keyboard Shortcuts

  • 1: Display input color.
  • 2: Display input velocity.
  • 3: Display output.
  • space: Pause animation.

XeSS-FG DX12 Basic Sample

Demonstrates basic XeSS-FG integration with DirectX 12.

Windows Build Steps

Run a 'Developer Command Prompt for Visual Studio 2019', then execute the following commands:

cmake -S . -B build
cmake --build build --config Debug --target ALL_BUILD

Command Line Options

  • -gpu_id value: Selects GPU by ID.
  • -async: Enables asynchronous flip.
  • -fps value: Forces the sample to run at a specified FPS.
  • -maximized: Maximizes the application window.
  • -width value: Sets the window width.
  • -height value: Sets the window height.
  • -top: Makes the window topmost.
  • -tag_interpolated_frames value: Tags interpolated frames with purple stripes (default: true).
  • -fullscreen: Starts the application in exclusive fullscreen mode.

Keyboard Shortcuts

  • 3: Toggle frame interpolation ON/OFF.
  • space: Pause animation.
  • F3: Switch between 1080p and 1440p.
  • F4: Switch between exclusive fullscreen and windowed mode.
  • F5: Display only interpolated frames.
  • F6: Tag interpolated frames.

XeLL DX12 Basic Sample

Demonstrates basic XeLL integration with DirectX 12.

Windows Build Steps

Run a 'Developer Command Prompt for Visual Studio 2019', then execute the following commands:

cmake -S . -B build
cmake --build build --config Debug --target ALL_BUILD

Command Line Options

  • -gpu_id value: Selects GPU by ID.
  • -async: Enables asynchronous flip.
  • -fps value: Forces the sample to run at a specified FPS.
  • -fullscreen: Starts the application in exclusive fullscreen mode.

Keyboard Shortcuts

  • l/L: Toggle latency reduction ON/OFF.
