Unreal 5 Vr Template runs with low fps and screen stutters, Why?

Using VR Template:

In Editor in VR - runs pretty good.
Made a Windows Package - runs terrible choppy.

Does someone knows what might be going on?
Well as I understand, if it runs great in the editor in VR, it will run EVEN better when its a Windows dedicated package.
I mean, are the different scalability settings in the Windows package than running it in the editor?
