    Then I must be hallucinating that my frame rate smooths out in comparison to only forcing VSync, which results in framerates of only 60, 30, 20 etc.
    It stops working however if you alt+tab out of the game.

    Where do you get your information? In the driver it says nothing about being OpenGL only. I stopped using D3DOverrider since RivaTuner support was dropped, because this works nowadays.

    While he didn't go into any details, repi, one of DICE's rendering architects, said that it was important to them to have Triple Buffering enabled still with VSync OFF.

    It used to say in the description that it was for OpenGL only, but since it doesn't say it anymore i thought they had enabled it for D3D as well.

    I sent a PM to ManuelG a few months ago asking if it worked in D3D but got no reply.

    But TB is at the driver level, which is still unsupported in DX based games. Using a 3d party app will fix that.

    Well sometimes it can help to have 3rd buffer, I noticed it mostly by texture streaming games (BF3, DeusEX HR ingame option).. Also by Metro2033 it helped with smoother picture (in driver option less jitter/stutter) + threaded optimization - on. At first i thought its like frames to render ahead but this is just half-way, it needs triple buffer to fully kick in. I saw this by BF3 spawning and in heavy combat (lots of explosions)..

    Anyway I just shared my findings and maybe it will help others too, that's all.

    Enough from me about triple buffer, cya. :)

    I think this rule no longer applies. Most games have this implemented by themselves anyways. I almost never see this VSync framerate problem in games I play unless I force through the control panel.

    I used to force this all the time in the control panel, but it causes glitches or perfromance issues for some games now (e.g. BF3), so now I just force it for the games that do not have an ingame VSync option.

    I think it still applies, but since most games support it anyway it may just look like it "does something". Kind of a placebo. Considering the amount of VRAM on modern cards it doesn't hurt, except for the additional input lag of up to one frame.

    As already said, this may be specific to their Frostbite 2 engine. And unfortunately, even developers often mix up the terms render ahead and triple buffering. Since there are both RenderDevice.TripleBufferingEnable and RenderDevice.ForceRenderAheadLimit commands they'll probably be utilizing both, but without knowing the engine's internals we cannot know in which way. If render ahead adds to the tb delay, well that explains why it feels so sluggish with tb on and a render ahead limit of 3, may mean up to 80ms of additional delay which is almost at console level.
    From a logical point of view, there's no reason tb would give an advantage without VSync.

    1. No, I can show that it works in Metro2033, but I am too lazy to make a video. If you really really want to, I could make one though, but I invite you to try it out for yourself and look carefully at the framerate with FRAPS or Afterburner. The triple buffering fails when you change graphics settings or alt+tab out of the game, though.

    2. No, it can be faster than just double buffering. I invite you to read the example just on wikipedia.

    I have a problem whit them :
    The drivers work great on my gigabyte 460 but on my new Gigabyte GeForce GTX 660 Windforce OC it has 2 bugs:
    It adds more power to the card and the Clock is higher (10%), and the clock is not going down on IDLE. on 305.27 the drivers that come whit the card all is ok.
    So no go for me at this time, still i want to know if someone else has the same problem.:question:

    Thanks for the link, :thumbup:



    btw, for those that say triple buffer is useless if vsync is off
    As you can see its not a placebo ;)


    And BF3, Hard Reset, DeusEx Hr and a few more are all stabler with triple buffer on (vsync off). There is no real extra mouse lag, well unless you use 3-4 frames to render ahead and low mouse dpi sensitivity. :nerd:


    Actually now that i've read this, im gonna experiment with d3doverrider by other games that feel stuttery or jitter if vsync is off, maybe its only this "In double buffering the program must wait until the finished drawing is copied or swapped before starting the next drawing. This waiting period could be several milliseconds during which neither buffer can be touched."

    Can someone confirm this to actually being useful without the fear of breaking game performance, MP wise?

    I copied this from http://www.tweakguides.com/NVFORCE_6.html

    Maximum Pre-Rendered Frames: If available, this option - previously known as 'Max Frames to Render Ahead' - controls the number of frames the CPU prepares in advanced of being rendered by the GPU. The default value is 3 - higher values tend to result in smoother but more laggy gameplay, while lower values can help reduce mouse and keyboard lag. However extremely low values such as 0 may hurt performance, so I recommend this option be kept at its default of 3 globally, and only adjusted downwards in specific game profiles. Remember, in most cases mouse lag is due to low framerates, so adjusting this option is not an automatic cure to lag issues, nor should it be the first thing you try. Finally, it only works in DirectX games, not OpenGL games.

    My question is shoud I set it to 3, as my default settings were - application controled, and does this option have any impact in the MP games?

    ^
    If you notice mouse lag then use 1 or 2, 0 is not available anymore. If game becomes unstable (more fps fluctuations) try 2 instead of 1.

    Love these drivers but why is 3DMark11 giving me the "Graphics driver is not approved" error?

    I never had fog issues with my 7970's.

    If this was or is a bug on AMD, it was squashed drivers ago.

    No idea why, but my buddies GTX 690 experiences massive slowdowns in smoke though, say from tank fire.

    It keeps him above 60 FPS though, no idea whats going on with the slowdowns.

    I just said that it's not a driver problem. It's a BF3 problem.
