 - Massive work integrating latest advances with [OpenVINO](https://github.com/vladmandic/automatic/wiki/OpenVINO), [IPEX](https://github.com/vladmandic/automatic/wiki/Intel-ARC) and [ONNX Olive](https://github.com/vladmandic/automatic/wiki/ONNX-Runtime-&-Olive)
 - Full control over brightness, sharpness and color shifts and color grading during generate process directly in latent space  
 
-Plus welcome additions to **UI performance, usability and accessibility** and flexibility of deployment  
+Plus welcome additions to **UI performance, usability and accessibility** and flexibility of deployment as well as **API** improvements  
 And it also includes fixes for all reported issues so far  
 
 As of this release, default backend is set to **diffusers** as its more feature rich than **original** and supports many additional models (original backend does remain as fully supported)  
 
+Also, previous versions of **SD.Next** were tuned for balance between performance and resource usage.  
+With this release, focus is more on performance.  
+See [Benchmark](https://github.com/vladmandic/automatic/wiki/Benchmark) notes for details, but as a highlight, we are now hitting **~110-150 it/s** on a standard nVidia RTX4090 in optimal scenarios!  
+
+Further details:  
 - For basic instructions, see [README](https://github.com/vladmandic/automatic/blob/master/README.md)  
 - For more details on all new features see full [CHANGELOG](https://github.com/vladmandic/automatic/blob/master/CHANGELOG.md)
