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…

We’re just going to jump straight into SSAA here, as even the 7970CF can get 61fps at 5760 with it. This is the first game that the GTX 690 solidly beats the 7970CF for reasons other than bugs; at 5760 with impeccable image quality the GTX 690 is ahead of the 7970CF by 38%, and even at 2560 that’s a 27% lead. In fact you could nearly play Portal 2 with SSAA and with 3D Vision at 2560, at 60fps, if there was even a 3DV monitor at that resolution.

With that said, SSAA really clobbers the GTX 690. This is the worst performance we’ll see relative to the GTX 680 SLI, as the GTX 690 only reaches 93% of the GTX 680 SLI’s performance at 5760, and 90% at 2560. Thankfully for the GTX 690 it’s the difference between 120fps, and more than 120fps.

    Keep laughing, this card cannot solid v-sync 60 at that "tiny panel" with only 4xaa in the amd fans revived favorite game crysis.
    Can't do it at 1920X guy.
    I guess you guys all like turning down your tiny cheap cards settings all the time, even with your cheapo panels?
    I mean this one can't even keep up at 1920X, gotta turn down the in game settings, keep the CP tweaked and eased off, etc.
    What's wrong with you guys ?
    What don't you get ?

    Currently the only native 120Hz displays (true 120Hz input, not 60Hz frame doubling) are 1920x1080. If you want VSYNC @ 120Hz, then you need to be able to hit at least 120fps @ 1080p. Even the GTX690 fails to do that at maximum quality settings on some games...

    It can't do 60 v-sync at 1920 in crysis, and that's only on 4xaa.
    These people don't own a single high end card, that's for sure, or something is wrong with their brains.

    You must be talking about minimum fps, because on Page 5 the GTX690 is clearly averaging 85fps @1080p.

    Tom's Hardware (love 'em or hate 'em) has benchmarks with AA enabled and disabled. Maximum quality with AA disabled seems to be the best way to get 120fps in nearly every game @ 1080p with this card.

    You must be ignoring v-sync and stutter with frames that drop below 60, and forget 120 frames a sec.
    Just turn down the eye candy... on the 3 year old console ports, that are "holding us back"... at 1920X resolutions.
    Those are the facts, combined with the moaning about ported console games.
    Ignore those facts and you can rant and wide eye spew like others - now not only is there enough money for $500 card(s)/$1000dual, there's extra money for high end monitors when the current 1920X pukes out even the 690 and CF 7970 - on the old console port games.
    Whatever, everyone can continue to bloviate that these cards destroy 1920X, until they look at the held back settings benches and actually engage their brains for once.

    Well not if you want to do consistent 120FPS gaming. Then you need all the horsepower you can get.

    Hell my 6970 struggles to maintain 120FPS, and thus makes the game choppy, even though it's only dipping to 80fps or so.

    So now that I have a 120FPS monitor, it's incredibly easy to see stutters in game performance.

    Time for an upgrade (1080p btw).

    Actually, they use the 5760x1200 because most of us Anandtech readers prefer the 1920x1200 monitors, not because they are trying to play favorites.
  • CeriseCogburn - Thursday, May 3, 2012 - link

    Those monitors are very rare. Of course none of you have even one.
  • Traciatim - Thursday, May 3, 2012 - link

    My monitor runs 1920x1200, and I specifically went out of my way to get 16:10 instead of 16:9. You fail.
  • CeriseCogburn - Friday, May 4, 2012 - link

    Yes you went out of your way, why did you have to they are so common, I'm sure you did.
    In any case, since they are so rare the bias is still present here as shown.
