Introduction
With the R520 core just round the corner, the enthusiast scene is heating up with ever increasing discussion of the performance and new features of these new cards. A-vivo and Crossfire to name a few, however there is also another feature that seems already implemented into ATI’s previous line of cards. This is of course Adaptive Anti-Aliasing, ATI’s supposed answer to NVIDIA’s Transparency Anti-Aliasing offered on their Geforce 7800 range. Introduced as a feature with the new 5.9 drivers, it offers sharper and clearer images but requires modification of registry values. This article will therefore show not only how to activate AAA but the benefits it will bring to your gaming experience.
How to activate Adaptive Anti-Aliasing
Activating this new feature is simple. However it will require its end user to download the 5.9 catalyst drivers recently released by ATI. It is preferred that the user downloads the catalyst control centre (CCC) for use with this feature as it will be an easier task to apply it after the registry modification is complete. This is not to say that AAA can not also be used with the preferred catalyst control panel (CP) but this will require the user to download the ATI tray tools program from Here.
With my brief introduction now over it is time to enter the registry. Using regedit we are presented with a program that has listed file names on the left hand screen and a blank area on the right. We will be ignoring this for now but will instead but using the search function accessed by selecting find from the drop down edit menu at the top of the screen. The line ASTT_NA needs to be inserted into the “Find what:” box, once this is done click the “Find next” button and wait for the search to be completed.
You should now be presented with a screen like this:
With the ASTT_NA command selected you must use your right mouse button to access the drop down menu, from there you must choose “Modify”, this should be set to “0” (without the quotation marks). With this done you must proceed to change every ASTT_NA’s command to 0. To find the next command you simply click the edit drop down menu and select “Find Next”.
You have now successfully activated Adaptive Anti Aliasing. To Finish the registry modification reboot then you will be ready to active your new feature and begin to enjoy it.
