...until I turned AA up to 8

Not bragging but even with 4 AA at 19 x 12 there were jaggies ahoy.

And the flickering of jaggies hurts my eyes. I had it 4 AA but they were still present.

Turned it up 8...way way better. Everything is so crisp and clear that my eye strain has eased up.

Especially in NV were you have a bright sun and many reflection decals surfaces...walls, fences, objects. Those flickering decals and edges can really put the strain on.
The graphics went from decent to actually pretty good..not Crysis 2 or Witcher but still good enough.

No loss of performance. And really sharp..real sharp.

Lost all my saves ( 247 hours worth and one character was actually 2 hours from finally the MQ ...got it on release...sad I know )

Started playing again and the glare , jaggies etc was kinda turning me off. Turned it 8 AA on a lark.
Knew my card could do it but wondered about dropping below 60 FPS.
Didn't miss a beat.

19 x 12 , 12 AF, Ultra, V-sync on...60 constant ( Except the lower level of Vault 22 and one of NV sewers..weird )

Never thought that just bumping the AA a notch could make such a difference in NV.

Already back to lvl 19. Started again yesterday.

Game looks good almost like an HD upgrade...

Did I mention it looked sharp...?
