Feedback Adding/Removing/Modifying properties is very very slow

    I am working on a complex graph with several nested subgraphs, around 50 properties and a decent amount of nodes.

    I know these are a lot of properties, but interacting with them has gotten so so slow. When I want to add a new property, shader graph hangs for several seconds (maybe 4 or 5) before adding it. Otherwise performance seems good (moving, connecting nodes).

    It's getting close to unusable for me with a large graph. Not only modifying properties is slow, pressing play with the shader graph window open causes an even longer editor freeze before playmode starts.

    I created a stripped down version and filed a bug report:

    Case # 1209047

    Hoping Unity Shader Graph devs can take a look at this before 2019.3 ships.

    Similar problem here except when i create a property shader graph freezes indefinitely. The only thing that un-freezes it is going in and out of play-mode. So each time i create a property i have to play, exit play, create property, play, exit play etc etc. Very slow and frustrating process.

    Hi, we are investigating it. The issue goes beyond just our code source so we're working with other teams to try and resolve it. We understand it's important but we can't give an estimate on when we'll have a solution.
