So I created a few quads in unity and gave them an unlit shader. When I rotated them, they are heavily pixelated. Check screenshot.
I tried two things to no avail:
1. Changing anti-aliasing settings to x4 gave a decent result but still not production worthy result. Theres still a lot of pixelation.
2. Tried rotating the camera instead. Still no good.

2) It looks like your resolution is pretty low, maybe because you are running it in the editor. With full screen 1920x1080 and AA, your pixels should be crisper than a fried pickle.
If its not working at all check your video driver Global and application specific settings and make sure your not forcing AA off (so it wont matter what you do in unity)
And if that is all ok then do as suggested in the posts above.
Cheers all
