Playing any game with SSAA isn't realistic regardless of hardware - due to the way SSAA renders, it basically completely shuts down performance.. The game plays great for me with ultimate quality / FXAA with these new drivers, so as long as you lower the AA to a reasonable level it should play fantastic.
Honestly, I don't know of why SSAA is even included in the game. The only games that I would fathom using SSAA on are older ones - Certainly nothing current or intensive, there's just no way to make supersampled work.
I disagree. I wish every game includes SSAA as an "option" to improve image quality. I've been using SGSSAA whenever possible with games. (I'm not sure why people complain about options.)
Witcher 2 with ulbersampling option, Project CARS with (downsampling = SSAA) option, SleepingDogs with ExtremeAA (SSAA) option were all great.
I understand that 4xSSAA (OGSSAA) is quite crazy (and some might call it an overkill) at 2560x1600p because it's essentially rendering at 5120x3200p and scale it down to 2560x1600p. However, it's still an improvement in term of image quality.
And yes, I admit that difference between 2xSSAA and 4xSSAA at 2560x1600p resolution is very subtle at best.
Good thing is, with wireless XBOX360 controller, 3rd person games like Tomb Raider is perfectly playable at constant 30 fps.
This game doesn't require high fps nor fast reaction times like some of the competitive FPS do. (Counter-Strike, BF3 etc). Constant/locked 30 fps is better than frame rates jumping all over all the place.
I prefer 4xSSAA at 30 fps to 2xSSAA at 60 fps for games like Tomb Raider.
I'm actually surprised 30s is the lowest you've seen with 4X SSAA at 2560x1600. I'd expect it to be in the teens.
Had another brief round of Tomb Raider last night. Lowest fps was 22 briefly. So it's below 30 fps.
