Has anyone else found out that the Editor is extremely slow and choppy in 2017.2.0f3? I'm on a high end desktop and since switching to 2017.2 from 2017.1 my development experience has become absolutely horrible. Every single alt+tab back to the editor takes 1-2s for the editor to come back. Pressing "play" to get in takes something like 10s now to launch play mode, and for the first 15-20 seconds performance in the actual game window is something like 20-25FPS, and finally it settles to go to 60FPS smoothly. Clicking between prefabs in the Assets list can take 1-2 seconds... virtually every single thing I want to do is just *slow*. Has anyone else had this? Any ideas how to fix?
