 ## Introduction
 
+QCefView is a Qt-based QWidget that encapsulates CEF (Chromium Embedded Framework). With QCefView, you can build your application UI using modern frontend development techniques, boosting project efficiency while keeping UI and business logic decoupled. Most importantly, QCefView enables seamless CEF integration within Qt applications.
 
-QCefView is a Qt based QWidget which encapsulates [CEF](https://bitbucket.org/chromiumembedded/cef). With QCefView you can build your application UI in frontend developing way to boost your project. And what's more you can completely decouple the UI and business logic in your project. The most important thing is to be able to better use CEF in Qt.

-## About OSR mode
+## OSR Mode & Hardware Acceleration
+
+QCefView supports **CEF offscreen rendering mode (OSR)**, which is **enabled by default**. To disable OSR mode, set `setWindowlessRenderingEnabled` to `false` in the configuration:
 
-QCefView supports CEF offscreen rendering mode and this feature is enabled by default at runtime, to disable OSR mode you need to set the config item  setWindowlessRenderingEnabled to false
 ```cpp
-  QCefConfig config;
+QCefConfig config;
 
-// WindowlessRenderingEnabled is set to true by default, set to false to disable the OSR mode
- config.setWindowlessRenderingEnabled(false)
- ```
+// OSR (Windowless Rendering) is enabled by default
+// Set to false to disable OSR mode
+config.setWindowlessRenderingEnabled(false);
+```
 
-QCefView currently uses Qt Software Rasterizer as the backend paint engine for best compatibility, thus the rendering performance is not so good to be applied for all business scenarios. If you want to host WebGL games, video sites or some other Web Apps with high rendering performance, Non OSR mode (Native Child Window mode) is recommended.
+### Enabling Hardware Acceleration (CEF 125+)
 
-## Question
-### Why not OpenGL/DirectX/Metal?
+Starting from CEF 125+, GPU resource sharing is generally available. QCefView now supports **hardware acceleration** for OSR mode. To enable it:
 
-QCefView was designed to be a common Qt widget for Desktop application, so the compatibility is the first important requirement. We can switch the backend engine from Software Rasterizer to OpenGL/DirectX/Metal but this will increase the complexity and decrease the compatibility of QCefView. 
+```cpp
+QCefSetting setting;
 
-For example if we use OpenGL as the backend engine then all the applications with QCefView introduced will be switched to OpenGL backend automatically. I believe not all users want this to happen. 
+// Enable hardware renderer (only applicable in OSR mode)
+setting.setHardwareAcceleration(true);
 
-DirectX/Metal are platform dependent and they are not supported natively by Qt. If we provide QCefView with extra dependencies individually, this makes QCefView so different with other components in Qt Framework.
+// Set frame rate limit
+setting.setWindowlessFrameRate(240);
+
+// Create the QCefView widget
+auto qCefViewWidget = new QCefView("https://www.testufo.com/", &setting);
+```
+The performance comparison：
+<div align="center">
+<a href="docs/images/osr-software-vs-hardware-rendering.png"><img src="docs/images/osr-software-vs-hardware-rendering.png" alt></a>
+<br/>
+<em>Software VS Hardware Rendering</em>
+</div>
 
-But if you must use OSR and the rendering performance is vital, you can try to switch the backend with whatever you want.
