does a project need to be rebuilt to switch from VR to non VR?

I setup a project to use the oculus rift. When I launch the game I use the launch in VR button, and everything looks as designed. However, if I use the normal play in editor button, the screen looks strange. If I had to guess I would say the resolution scale remained low from the VR. But for the life of me I cannot seem to reset it. I’ve tried the console commands r.screenpercentage= and I’ve tried editing the defaultEngine.ini to correct this but it doesn’t seem to change anything. When I first setup the VR I had to toggle a button called instanced stereo which I believe meant I had to rebuild the shaders/ project. So this post is two parts. How can I get it back to look normal in Play in Editor, and can I switch between the two without requiring a rebuild?
