Super Laggy when moving vertices, in edit mode, where it shouldn't be laggy I'm a new modeler here, and its been pretty smooth, until now. I have been working a Dodge Challenger for the past couple of weeks, with almost no speed bumps or anything. With subsurf, The total model adds up to 235k tris, 117k faces, and 123k verts. I upgraded my GeForce driver to 457.xx.  Didn't open blender until the next day. The next day, I tried to move a vertice in edit mode with sub surf set to 2. It was VERY slow. About 2 fps. For the record, it didn't do this before, so it's not my laptop. My laptop has a 2-core i5-7200U, with a 2gb GeForce 940mx, and 12 gb RAM.
I tested on two different computers, both having the same outcome. First, my dads laptop with a similar build. Super laggy when Trying to edit a vertice in edit mode with sub-surf. Then, our desktop, with an older i7, 6gb GeForce GTX1060, and 16 gb RAM. Same outcome.
I dont know what to do at this point. 250k tris shouldnt be laggy, but it is. Or , im stupid, and it should. I just remember editing the whole 200k face mesh with sub surf visible.
Also for the record, the model was made in 2.79x. Yes, I know. I opened it the most recent version, and it still  did it.
If yall can help, or just tell me it is what it is, id be happy.
I have found the issue. Its the shrink-wrap modifier I used for the side markers.
