Portal 2

Portal 2 continues the long and proud tradition of Valve’s in-house Source engine. While Source continues to be a DX9 engine, Valve has continued to upgrade it over the years to improve its quality, and combined with their choice of style you’d have a hard time telling it’s over 7 years old at this point. Consequently Portal 2’s performance does get rather high on high-end cards, but we have ways of fixing that…

With this latest generation of high-end cards Portal 2 performance is so high that it’s more than practical to play with SSAA, and that’s where we’re going to focus today. At all resolutions and anti-aliasing options the GTX 670 can surpass the 7970, but this is especially the case with SSAA. At 2560 the GTX 670 is just shy of 60fps, while the 7970 manages only 48fps and the 7950 39fps. SSAA is the ultimate lavish feature, and although Portal 2 is perfectly playable on AMD’s cards without SSAA, SSAA is also the ultimate option for image quality and there’s no good reason not to use it with cards that perform this well.

At this point it’s not entirely clear why the GTX 600 series does so well here (both AMD and NV use SGSSAA), especially given the fact that the Radeons have a memory bandwidth advantage. But regardless of the reason at 2560 the GTX 670 is looking pretty good. For that matter this also happens to be one of the stronger games for EVGA’s GTX 670 Superclocked; the performance gain at 2560 pushes past 4%.

    If you want to see what we really have GTX670 performance in games is worth taking a look at this overview:

    These are the comments of people reading AnandTech articles? Gamers? Enthusiasts? WHERE?? A bunch of trolls barking at each other. Not one useful comment, not even one to express USER oppinion after USING the card for a while. NOT ONE to say if the colors look better or worse than on the last generation card or the competition ones. You are all just a bunch of ....spit on you trolls!

    I've been holding this question unaswered in me for years. I would like to know which card produces the best image quality given the same conditions and settings, a nVidia one or Ati/AMD one. Image quality as in the closest to reality or closest to what the image producer indended. And If I get an aswer I want it argumented, no "because it has PhysX!" "because it rocks!" childish like considerations. Picture examples would be greatly apreciated. Thank you, have a good day and try not to troll too much.

    It had to be like that of course. Always against me. Two games I want to play,only two I don;t care about the others: Crysis and The Elder Scrolls V: Skyrim. And what do I see?? nVidia will work on one but not the other, AMD will work on the other one but not on the first one. What the f...k is that!?? What card should I get and why? Pictures please. Money is a concern.
