I was editing a landscape and suddenly the arrow keys are moving the scene around about 1/20th of the speed that is usually does. This is making painting textures quite slow to achieve now.
I saved and re-loaded Unity but the problem remains.
Does anyone know what I accidentally set to cause this micro-movement setting? It also does it when you select the hand tool and hold the left mouse button down to move.
I fixed my issue on accident by holding right-click and scrolling (this sets the editor speed). My speed somehow got set to 0.01x, so I cranked that puppy up to 2.00x and am back in love with my large scene. Hope this helps someone!
