Why doesn't Anti Aliasing work in view port?

I know it works when you render but I mean like the wire frame etc in the viewport why doesn't it work?

Because AA is a resource intensive feature it would either bring the viewport to a halt or crash blender on complex scenes.

AA hopefully wont crash blender when put to the final render because the entire scene is sort of compiled. When put to the final (or even a preview render if AA is enabled) blender can pre-allocate its resources better than if you were flying through the viewport like a maniac.

Also there isn't anything to smooth out on a wireframe, if your getting what looks like jaggies the edges on the mesh probably aren't straight, try CTRL to move incrementally or holding SHIFT to move smoothly.

[Note you cant press and hold CTRL + SHIFT, pick one and only one.]

Wel thats weird since 3DS Max has AA in the viewport.

Also I have a GTX 1080 so I doubt this will move slow it sure as hell doesn't move slow in 3DS max

3DS Max has a team of vigourously vetted paid staff blender foundation rely on donations and volunteers.

Also you could have a GTX TITAN X the viewport is only as good as its coding and optimisation. Blenders viewport is OK but compare it to other 3D programs and then well...you see the difference.

You can crank the settings up there if you want but even with a GTX 1080 I would expect some slowdown on complex scenes
