Why GFX card with more RAM?

GPU may be not 100% loaded if it is held back by vsynk too.

Triple buffering is in the default Nvidia panel above Vsync no need to add any other programs.

This one works for OpenGL games only IIRC. This could have changed though as I did not use NV recently.

Enabling Triple Buffering for OpenGL-based games such as Doom 3, Quake 4, Prey or Enemy Territory: Quake Wars is very simple - go to your graphics card's control panel and enable it from there. However this won't work for enabling Triple Buffering in Direct3D-based games, which are the bulk of modern games. Instead, you will need to use a utility called Direct3D Overrider (D3DOverrider) which comes with free RivaTuner utility.

Many reports of "terrible fps" are caused by not switching it On imho having vsynk On.
On my ATI card I have 30 fps with triple buffering off and 40-50 fps if it is on. I force it via creating a game profile for CloD in ATI Tray Tools.
I guess this allows my card to be 98-100% loaded according to a monitor when many others report 70% load only.

PS. Moreover I noticed if vsynk is switched on both in game and in drivers it results in further fps reduction because of some conflict. I prefer to run the game with vsync off recently to get rid of all these limitations altogether and stop screen tearing by reducing graphics settings, overclocking and other system optimisations.

Well I don't know if the Athlon II Black Edition cpu is the bottleneck but
my setup produces stable playable fps in DCS-A10, ROF, ARMA2 and
som other titles. It is just here that the problems occur.

EDIT:

I made a test. I turned off VSync and the fps go up but the tearing is completely unbearable when
looking through the propeller arc. That would give me epilepsy even though I don't suffer from it.

The only remedy is to turn on the filter and live without the prop arc. That at least seems to give
acceptable fps without to much tearing even though it's not nice.

The intresting part is that the CPU now gets taxed up to 60% as opposed to about 40% and the
GPU's get taxed up to 95% each as opposed to not above 40%. This to me is very strange!

Im just repeating what others have said but have you? Checked the performance section in the forum?

1) forced the AA in the Ati tray tool to 2x or 4x or off and shut it off in the il2 video options.

2) forced vsync in tray tool, off in game

3) maybe set textures to performance ati tray panel(can you do that in ati)

4) go to RUN and enter "msconfig" go to start up and shut off everthing at start up, go back if you need that stuff later.

5) go to advanced system properties and select performance under the visual effects tab also r click on desktop and personalize so you dont have the aero if you have win 7.

6) lower the trees, lower the buildings, grass off, ssao off, everything else med or so except texture(makes planes look good so that one last)

If this is the case than turn vsynk back on but force triple buffering ON in
ATI Tray Tools >> Game Profiles >> Create a profile for Launcher.exe >> Direct3D tweaks tab >> "Force to use triple buffers" checkbox. >> Save the profile.

Epilepsy filter is not a good solution imho.

I will try ATT and RadeonPro if that doesn't work.

I have however tried with both applications before and done everything suggested
even deinstalling everything and just installing the radeon driver and operate it with
ATT but that leaves crossfire disabled since ATT in the latest version is broken in that regard.

It doesn't seems to fare well with my system unfortunately. Perhaps the solution is to
test with a monitor capable of 120Hz?

But i will keep fiddling, sooner or later i will perhaps get it to a state where it is operational.

I have monitored CoD using well in excess of 2 Gb memory on my card and it climbs slowly but surely ever higher. I believe there is a memory leak in CoD.

Ataros's suggestions do nothing for me that I can notice.

Interesting stuff Ataros.

It seems since Vista Win 7 triple buffering has had some changes.


"Q
Can anyone let me know whether the triple buffering and vsync in the Nvidia Control Panel work for DirectX games?


A
The 'triple buffering' option does affect rendering behavior within the modern DirectX APIs.
The 'vertical synchronization' control is less cooperative: in Windows XP, it applies to both OpenGL and DirectX 9 APIs; in Windows Vista and Windows 7,
it only affects the OpenGL APIs."

That's curious. I get lots of tearing in W7 DX API's when vsync is off and none with it is on, so it appears it does something in DX???

I think he must know what he is talking about

However there are many different opinions and discussions on other forums like guru3D, etc. Some say only OGL lines of code are present inside the drivers.

Another opinion is that an application itself must have triple buffering enabled and some applications enable it by default when a user switches vsynk on inside the app (but not in drivers). Some apps like Left for Dead and BF3 have tripple buffering as a separate checkbox in settings.

We do not know how CloD is programmed and need to benchmark it with various settings to find out. IIRC when I switched vsync ON in drivers I had some issues. Maybe ingame CloD vsync uses TB.

ATI Catalyst still lists triple buffering inside OGL section only. I run vsynk off to be on a safe side. Having TrackIR smoothing set to max helps me to avoid tearing. It still happens but on very rare occasions. Reducing settings also helps with it.

For NV users to be on a safe side I would install D3D Overrider to force triple bufering ON and test it. It is free
Download and install recent RivaTuner, find the D3D Overrider executable inside the install folder and copy it somewhere. you can now uninstall RivaTuner. D3D Overrider does not require RivaTuner to run.
