----

While working with Bolt 2.0 I noticed the editor window uses a large amount of GPU resources. Unity will idle with 0% GPU but simply having the bolt graph window open jumps that up to 45% even if Unity is not in focus.

  1. Resolution Note:

    Rendering cost has been reduced by only rendering while the graph window has focus as well as capping the refresh rate

  2. Resolution Note (fix version 1.4.14):

    Rendering cost has been reduced by only rendering while the graph window has focus as well as capping the refresh rate

    Still high CPU usage with Bolt 1.4.15 and Unity 2020.3.25f1, Windows 10.

    Only happens with extra Graph Inspector and Variables windows attached. No problem with the Graph itself and when Graph Inspector and Variables are visible within the Graph window.

    Found in Unity 2020.2.0a18 and confirmed with the Unity QA team.
    Really glad to hear they're working on a fix!

    Same issue on Unity 2019.4.5f1 and Bolt 1.4.12.
    The heavy load happens even if no graphs are selected/shown, but the window is open.
    It also seems to ignore Unity's interaction mode frame throttling settings.
