Beware ATI catalyst Version 11.6 halved my FPS compared to 11.5

I thought Triple buffering improved frame rates when VSYNC is enabled in game?

Exactly. This is what I mean. Without TB you have either 60 or 30 or 15 fps if vsync is on, you can not have 40 or 50 fps.

thought triple buffering only related to open gl?

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 enabling Triple Buffering for Direct3D-based games - the bulk of modern games - actually requires more effort. You will need to use a utility called D3DOverrider which comes with RivaTuner - see the bottom of this page of my Nvidia Forceware Tweak Guide for more details.

Fro ATI use ATI Tray Tools as described in my previous message.

i have vsync on, and triple buffering off, and i dont get my fps halved.

I tried the 11.6 drivers and my performance plummeted through the floor. I know my sig still says 11.6 but I've gone back to 11.5, where the performance was good.
With the 11.6 drivers, I was getting just over 20 fps average in the Black Death track, which is a little less than half of the normal. (High setting, for consistency.)

So yes, for me the 11.6 drivers are terrible.

It would seem that triple buffering causes more problems than it is worth.

1. If it is not properly supported by the game in question, it can cause visual glitches. Just as tearing is a visual glitch caused by information being transferred too fast in the buffers for the monitor to keep up, so too in theory, can triple buffering cause visual anomalies, due to game timing issues for example.

2. It uses additional Video RAM, and hence can result in problems for those with less VRAM onboard their graphics card. This is particularly true for people who also want to use very high resolutions with high quality textures and additional effects like Antialiasing and Anisotropic Filtering, since this takes up even more VRAM for each frame. Enabling Triple Buffering on a card without sufficient VRAM results in things like additional hitching (slight pauses) when new textures are being swapped into and out of VRAM as you move into new areas of a game. You may even get an overall performance drop due to the extra processing on the graphics card for the extra Tertiary buffer.

3. It can introduce control lag. This manifests itself as a noticeable lag between when you issue a command to your PC and the effects of it being shown on screen. This may be primarily due to the nature of VSync itself and/or some systems being low on Video RAM due to the extra memory overhead of Triple Buffering.

I haven't noticed any issue with the 11.6 drivers. Not using triple buffering.

Afaik triple buffering is only! for openGL.
In a directX game, CoD, its of no use.
