One of my blender files runs extremely slow, I'm guessing this is because it just contains too much content/complexity and the more I add the slower it gets. It's to the point that editing undo/redo will take like 20-30 seconds every time I press it. Is there any suggestions to how I can increase the speed on this? I should also mention that my scene contains grass.
Other questions talk about speeding up the whole program, not just for one project
