On a scene (Big scene, with many linked assets) I’m working on, if I hit spacebar to play, Blender is constantly optimizing shaders - this gets down to 1 remaining and then starts again. While this is going on, this slows my machine down massively

Any idea what could be causing this and how to optimize?
It looks like you’re playing an animation.
This happens when you run a material preview.
It usually runs once, but it will continue to run if there is a material change.
Try a rendering preview
Text info says that your scene has a huge amount of shaders to optimize.
What does your scene represent to contain so many shaders ?
