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.

    I have purchased 2 of the new Nvidia 600 series, a gtx 660 ti, which runs fine this far, but I would question if it was worth it's cost. I purchased a second cheaper gtx 650 because cost with the promised free download of Assassins Creed III made it best choice for second computer video card. The game download promotion is a lie, tigerdirect codes are not being honored by Nvidia and I informed tigerdirect but they are still selling these cards with the promise of free game download. This is a dishonest promotion by both firms, Beware!

    Why support firms that are promoting these video cards with a dishonest promotion. If the free download promotion has exceeded its allotment, then both firms should stop advertising it and promising a free game download they know is not going to be honored. Shame on them for promoting such lies to customers at Christmas. I will never buy from them again.
