Turn on TAA in game (will make it blurry, don't worry) and, if you got a good rig, try this:
Open notepad, create a file with that line in it:
Render.ResolutionScale 1.3000000
Save it as User.cfg and move the file to your game install folder (Default: C:\Program Files (X86)\Origin Games\Need For Speed).
Quality will be way better provided your PC can handle it. You can up the value to 2.0000000 if you have a beast of a rig.
