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."

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.
