Unity lagging after update?

Question

I've been working on a lightweight game with some friends. Today I updated Unity, and after about 30 minutes of loading time, I was able to edit my project again. But all of a sudden, Unity is being very slow. I try playing the game, and it is running at about 2-3 FPS. The current editor mode is DX11, but I tried forcing it to OpenGL and that only made it much worse. My computer should be able to handle it; I have a GTX 1080, 32 GB of RAM, and an i7-8700K. Can someone please explain what is causing t$$anonymous$$s, and how to fix it? Thanks in advance!

Hi! Are you using collab? There are some known issues related to collab slowing down the Editor as of 2018.1 (see e.g., https://answers.unity.com/questions/1501970/editor-laggy-and-very-slow.html)

For me, setting the game window's resolution in the Unity Editor to somet$$anonymous$$ng lower was all it took for the lag to go away. In my case, I usually tested my game on Full HD and then when I updated I started testing on 16:9 Aspect because Full HD was the cause of the lag.
