    That said, either AMD is cheating or have a serious driver problem.

    Yup smooth FPS is a key feature for smooth game-play..

    Yeah. I agree. After I installed 12.11, my Trinity Dual Graphics set up was really choppy but yield the same average fps, at least in sleeping dogs.

    Downgraded back to 12.10 and it improves a bit, but the problem still surface at times.

    I have a feeling this problem of high frame latencies is AMDs (ATIs) curse for a long time, yet till now noone seemed to be able to analyze this problem..

    Or was it well known fact among certain people and were they deliberately concealing it?

    Conspiracy theorists can initiate the long-term process of building their silicone castles from guesses and presumptions and become a neverending source of amusement for others, but for me as a 4-year ATI/AMD card user there is mainly one imortant thing to be aware of : If your eyes' sensitivïty is above average and you want to really fully enjoy your money spent on HW/SW to play videogames, you should definitely consider buying a card from Nvidia.

    Maybe 1 other thing : All the comparative articles and discussions' flamewars about whose card has the highest (average of) fps etc. are quite pointless because of this higher level of overall product polish and hw-sw optimalizations Nvidia has to offer gaming-wise.

    Hmm, smooth framerate is nice, but I'd rather have higher smoother framerate, then a locked, lower smooth framerate (if that makes sense). In other words, I'd rather have a consistent 60 FPS than 30 FPS, even though 30 FPS is easier to maintain on more hardware and game engines...

    Just did what this guy did:

    http://forums.anandtech.com/showthread.php?t=2289641

    And my HD 7850 is just as smooth if not smoother than my GTX 460 in the two games I tested.

    Just install RP and it will be smooth as butter.

    Well AMD needs to do more work on there drivers. Come out with some good stuff. Like maybe a fix to crossfire or trifire setups. I mean they develop and make the cards. So fix it with a real fix.Not the one that give 5% or 50%. SOMETHING BIG:3eyes:

    smoothness is not a need neither it's a necessary rule for amd's drivers target...

    so...you can't even prove that, pass on...you keep it up or wait for the miracle driver or switch to green, you can't ask a solution for a non-confirmed problem.

    Do you suppose this has anything to do with flip queue size or maybe AMD's triple buffering through CCC actually doesn't work? AMD claims triple buffering is automatic with vSync, but do you suppose that actually doesn't work?

    Yes yes, keep blowing the problem out of proportion. And throwing around theories.

    Now I wonder what causes "frame time" spike to 500ms they showed there. It's 1/2 of second.
    I do not get such problems. I have HPET enabled in BIOS. Tested my system for drivers which may cause High DPC latency and I do not have them.

    I honestly do not think they did any testing of that system to find which part of it causes it to stop responding for that long.
    Maybe it's network adapter, you never know till you do proper testing.
    They apparently did not since they just made quick article about random stuff.

    If it takes 0.5 second to render next frame I would like to not only see that VGA was not doing anything in that time, but even see that it was VGA driver that caused this delay.
    I can make one hour long video 120fps @120Hz, record it and there will never be such spike in "frame time".

    Then Skyrim is pretty fine game using pretty old "atimgpud.dll" for xfire stuff. I wonder what would be difference on that particular system if those guys used Radeon Pro to mask that HD7950 as GTX 660 and therefore got rid of that atimgpud.dll.

    There is another thing... Skyrim is not really engine which can be used to measure anything seriously.
    With all those bugs when you run it at high fps. Catapulting animals, objects which "flicker" & sound which goes away and back as they flicker.

    It was all fine and dandy with Techreport in September with Catalyst 12.7 beta:

    http://techreport.com/r.x/geforce-gtx-660/skyrim-beyond-50.gif

    Anyway I can't replicate the smoothness issue that Techreport is advocating with a 7950 on my 7850 in Skyrim at least.

    Here's how I tested: http://www.youtube.com/watch?v=Yj79q5oLm7o

    i5 760@4GHz | P55A-UD3 | Corsair XMS3 2x4GB 1600C9 | HD7850 2GB@1100/5400 | Skyrim is installed on a 1TB WD Caviar Blue | Win 7 64bit Pro, Cat 12.11 b11 | Vanilla Skyrim with high res textures, Max Settings, 2xMSAA, SMAA@Ultra, 16xAF

    Used RadeonPro to Force settings.

    vsync off, triple buffering off, flip queue size = default
    http://img717.imageshack.us/img717/9799/novsync.jpg

    vsync off, no triple buffering off, flip queue size = 1
    http://img145.imageshack.us/img145/5136/novsyncflipqueuesize1.jpg

    vsync on, triple buffering on, flip queue size = 1
    http://img405.imageshack.us/img405/296/vsynctriplebufferingfli.jpg

    Getting the huge spikes at similar intervals which I assuming is caused by other factors(game engine streaming in new data/area/textures etc...), not the card, so I was fairly accurate with my runs.

    Here's the save file if anyone wishes to try and replicate my runs, I hit bench key and run right after the guy finishes speaking:

    I checked out what you put up and maybe its like some have said as in its software related and the fix is really software. So maybe its in the device drivers them selves. I guess another question is has there been a modded device driver? Not just putting one driver on another type of card or changing files ,but a completely modded driver. (windows driver)

    So an HD7970 it's worst than a gtx670?
    can please someone explain better this driver problem?
    Really confused

    You have to view things more positive, after all AMD went out of their way to provide us with the flickering to distract from the jerkiness :grin:

    Possibly not. The test was performed with a HD7950 Boost only, Boost and Powertune could be to blame for occasional micro-stuttering. It's also not clear if it is a driver problem at all.
