It's my opinion that with active scatters (large scale) and booleans it will slow down the viewport by a lot. That's why we made an extensive xpresso-driven switchboard in our project template file to enable/disable certain groups of objects (UI0.jpg) and thus keep the viewport fast and tidy. With projectfiles up to 7GB, it's still lightning fast...

You could also try the "Force path tracing" option if time to first pixel is an issue,
did a quicktest on an current project for time to first pixel 1min16 and with force pathe tracing 1min20, so maybe not in all cases faster? Is there a guideline in which situation this should be faster, or when not?

I have grown fond of asset browser too, although I do the standard integration and store the images in asset browser, then when using the objects or materials I relink them to absoluth path on mediadrive (must do that for renderfarm anyhow), but can you store in the asset browser with the links integrity kept absolute to the disc???? I did not manage to do that so far so far and the textures are always linked to asset browser path...
PS:Do you already use the functionality to drag assets from the aset browser directly into the UI toolbars? (ANY asset such as objects/studio environmets/scatters/materials/preferences/render settings preset/...) I just LOVE that feature so much, and made multiple toolbars for even quicker access of stuff I use constantly (UI2 & UI3.jpg)
