Description

Executed the RenderPerf tests (Rectangle, WhiteText) for metal pipeline using the javafx sandbox metal branch code as of 29th May 2023.
The FPS value obtained with metal pipeline was significantly less when compared with the FPS value obtained with ES2 pipeline. 
Test execution result is attached.

Test environment details:
Platform: MacOS 13.3.1
Metal: Sandbox metal branch as on 29th May 2023
ES2: JavaFX Mainline

This shows that there is scope for improvement in graphical rendering performance with metal pipeline.
