By the way, I tried to load the LS3 file you sent me (375Mb).
Windows stopped responding while loading it, and I waited for 25 minutes before I lost my patience and had to restart my PC. In other words, your scene is too complex (and/or uses too many textures) for my PC and graphics card.
Please click on the i button in Settings. Then go to Build mode, zoom out so that most models in your scene are visible within the viewport, and let us know how many vertices ("Verts") your scene contains. A k means 1000, so as an example 6000k means 6,000,000 vertices.
