Wondering if anyone else is having this problem and / or have any solutions.
Rhino has started running extremely slowly to the point where even in wireframe the file is virtually unusable. Also making V Ray unable to render to any kind of decent image size (eg 2000 x 2000).
I have read some Reddit threads suggesting that Rhino is single threaded and CPU locked though this was some time ago (is it even true?) so perhaps there is just a ceiling to the speed at which Rhino can run
Can’t make the file significantly smaller - anyone have solutions?

Do you mean that a particular version that you have been running has suddenly started running slower on the same model? Or have you made changes in the Rhino version, Windows, your model or your hardware that brought the slowdown?
It is a topographical site model with several buildings, and v ray scatter geometries, scattering trees (though the number of non-scattered trees is v low), and a few low poly v ray meshes (cars)

Some of this might depend on your block instances. Rhino does have a problem with display speed of nested block instances. If you do a SelBlock and hide the instances, does the display get significantly faster? Another thing that might slow down the display is if you have curves with very fine linetypes.
