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…

The GTX 660 Ti is still fast enough for us to use SSAA, so that’s where we’ll focus today. At 1920 it can deliver 94fps with 4x SSAA, and even at 2560 it’s just shy of 60fps. Whatever NVIDIA changed with Kepler to improve its SSAA performance made it a monster here, which is made all the more impressive by the fact that we’re dealing with a memory bandwidth and ROP reduced version. It would appear the biggest bottleneck for SSAA performance here is the shaders, which makes this a near-ideal scenario for the GTX 660 Ti.

Overall the entire Radeon 7900 series falls to the GTX 660 Ti by a greater than 20% margin here, and even the GTX 570 is more than humbled. If NVIDIA could do this on more games then they’d be in an excellent position.

    Long story short, we were having CMS problems earlier so we were messing with the URL slugs. Not that the slugs actually matter, but it's been fixed. Reply

    You show $399, but the MSRP is $319. Reply

    A lot of em are going for $299, but why put anything in there but RELEASE PRICE on the chart - that way you can show the GTX570 at $349.
    Bias ? You decide.

    blanarahul, very insiteful comment.

    The GTX 660 Ti seems like a good "bang for your buck" card. NVidia should count itself lucky for having trouble keeping up with demand. My worry is they lose focus with the number of markets they are trying to fill. Something I am sure AMD will be watching for.

    Yes nVidia sure loses focus - uhh... loses focus...sales GREAT - loses focus...
    Biased stupidity ?

    They're not loosing focus, it's a new strategy and it must work wonders. Instead of releasing new products as quickly as possible and fill the market with all the parts from low to high-end performance, they get out the new higher-end parts and rely on their last gen cards to fill the holes.

    Clean out the shelves so dealers don't get stuck with older technology not selling. And at the same time, not taxing new fabrication process(28nm in this case) by needing alot more to fill demand in every way.

    If they had released this at 249$ they would have never been able to supply the demand. . .why not just go for the jugular of amd? Oh yeah balance and perceived value in the market, only hurts us really. Reply
