Major issues/Ati tray tools

    Sorry if this isnt the right place for my topic. I posted all over th
    web today hopping someone will find an answer

    Well heres my proble


    I tryed everything I can think of but nothing works

    I use ati tray tools. And I enable triple buffering for d3d games
    Like bf2. (I use the profile options)

    I get great fps. But after I play for a while or if I change maps m
    fps drops from 80ish to 50ish and lower. Sometimes 30 ish. I turn of
    triple buffering then the problem goes away so I know its tripl
    buffering for d3d thats doing this. Why does it kill my fps lik
    this? Is there any way to fix it?

    It works very well for the first map but then it just drops. I have n
    idea what it could be. Is there any options in TWEAKS that I coul
    change to fix this

    Does anyone else have this issue

    my computer / if it matter

    x800xt
    3.4g
    2g ra

    Really would like help. I have one game on my computer right now an
    its bf2 which I spend more time trying to figure this out the
    playing the game. I have been looking around the web for weeks for
    answer but nothin

    If there is no way to fix this, can I get rid of screen tearin
    without vsync

  2. _Use vsync_. I don't know why people have such a thing against it. The only
    time I ever turn V-Sync off is for benchmarking. Otherwise, syncing frame
    swaps to monitor refresh results in a tear-free gaming experience. If your
    monitor refresh is high enough (85hz or greater) you won't notice any frame
    rate limiting.

    if what you are saying is right.. then please explain thi


    With vsync off I get 60-85 fps + (very smooth game play) but a lot o
    screen tearin

    with it on I get 20-42 to 85 fps mostly 42 and lower...it shutters
    lo

  4. I can't explain that. Something else must be wrong. Enabling Vsync should
    not affect frame rates the way you've described. I could see a slight (5%...
    maybe...) performance degradation, but not what you are describing.

    dont wont to sound mean or anything but I do not think you understan
    vsync.

    fast answe

    caps your fps to refresh rate .. so lets say you have a refresh rat
    of 85.. and then your playing a game like bf2.. with vsync on ther
    is a limit to which and what your fps can become.

    dont know the exact numbers but its something like 2 15 42 85 fps et
    et

    so if you cant pull out 85 fps then you get 42 fps when you woul
    without vsync get 67 fps... see what i mean

    42 fps is fine but when I cant pull 42 even if its 41 fps i would ge
    the next option vsync can give me which becomes very lagg

    Not quite. Your instantaneous framerate, even within one second, actually
    fluctates quite a bit. On one monitor refresh cycle the video card may have
    a buffer swap. On the next refresh cycle the video card may miss it. So it's
    quite possible to get 60-70 fps when the refresh rate is 85 Hz.

    Triple-buffering increases framebuffer usage by 50%. At 1280x1024x32, 15.7
    MB would be needed for the framebuffer. With 4x FSAA that swells to 63 MB.
    On a 256 MB card, that's quite a significant chunk. There's a far greater
    possibility the card will have to resort to AGP-texturing, especially in
    games with large textures.

    One way of alleviating this is of course to run a higher refresh rate. A
    good 19" CRT should have no problems doing 100-120 Hz at 1024x768.

  7. I appreciate your prefixing this statement with "don't want to sound mean or
    anything". However, I do understand vsync... and very well at that. Vsync
    (Vertical Synchronization), simply put, synchronizes frame-buffer swaps to
    the current _vertical_ refresh rate of your monitor. The net effects of this
    are:

    1. Prevention of page or screen tearing (a visual artifact that occurs when
    a single monitor refresh cycle is comprised of 2 or more frame buffer
    outputs). Obviously the more "out-of-sync" the frame buffer swaps are with
    the vertical refresh of monitor, the worse the "tearing" will be.
    2. A degradation in frame-rate performance (assuming the video card can
    render more frames per second at any given point than the monitor refresh
    rate will allow).
    "Don't want to sound mean or anything, " but...If you already had the answer
    then what was the reason for the original post? :)
    Yes. V-Sync effectively sets a frame-rate ceiling equal to the vertical
    refresh of the display device.
    A 3D engine does not render at predefined frame-rate markers. In other
    words, the engine doesn't say "Well, can't render at 85, so lets fall back
    to 42, or cant render at 42 so lets fall back to 15." (at least it
    shouldn't). A 3D engine renders the maximum frame rate possible until it
    reaches a software imposed or V-Sync imposed limiter.
    I can see where you're going with this. Your logic is that when V-Sync is
    enabled, your frame-rate must be equal to some whole number that is a factor
    of refresh rate. You are partially correct though. Yes, your frame-rate will
    always be a factor of your refresh rate. It is mathematically impossible for
    it not to be. However, the factors do not have to be whole numbers. They can
    and will be fractional. In other words, just because you can't render 42.5
    fps (85hz/2) doesn't mean you fall back to 28fps (85hz/3). You could very
    well be (85hz/2.001). See what I mean?

    hmm

    I can not agree on that

    I read a long topic about vsync and how it works about 2 months ago..

    It was very easy to understand. Ill look for it and post back if i
    find it. Vsync kills your fps for some people as I have read all over
    the web.. So there is no way it is just me

    Anyways this is not my question. It was about triple buffering and ati
    tray tools so can we stick to the subject? I am gussing no one has any
    idea?



    I have done some tweaking with ati tray tools and Oc my x800xt so now
    the drop fps doesnt matter as much in certain areas..

    I would still like to know why it does this

  10. Can someone describe the visual effect of screen tearing and is there a
    good tutorial on the effects on memory usage and fps of monitor refresh
    and buffering? I guess trial and error is one way of optimizing card
    performance but I'd prefer to be knowledgeable enough to get close to
    optimum up front.

    Consider the possibility that triple-buffering under D3D may be broken in
    the current ATi drivers. It's definitely a good reason why the option is not
    available in the standard driver panels.

    Helpful? The thread regurgitates incorrect information.

    BTW, I still run 2x 12 MB Voodoo2 SLI in a secondary rig for older games.
    3dfx "pioneered" triple-buffering, yet the option is *only available in
    Glide and OpenGL*.

    i was not posting to help you. That info was for myself


    I dont know what your issues are?

    but triple buffering now works in All my d3d games.
    In certain games triple buffering gave me graphic issues etc but
    already knew it wouldnt work for ever game i have

    Also finding ways around it using ati tray tools tweak options and
    also Rage3D Tweak 3.9 options.. so now in bf2 my fps doesnt drop as
    much.

    I am gussing it has to do with memory being how bf2 uses so much of
    it.


    its 3 in the morning :p lol im going to bed
