    Do any of you guys have TAA enabled? Is there a performance enhancement over regular AA? Should I use it? Everywhere I look in ATi-TT and tweaking programs I see TAA this and TAA that so im kinda confused.

    If memory serves, it allows you to run, say, 4AA at the performance cost of 2AA. Look @ Karoush's guide @ tweakguides.com, it will give you a much clearer explanation.

    i want to use it but it locks my FPS at 85, it feels like vertical sync is on! but it really dont see anything on performance enhacements! i guess that if you have your aa enabled like 6x and you taa (i am not sure) but you will use 6x2=12xaa

    So your saying I can Enable 2XTAA and it will give me the same result as 4XAA performance and Visually?

    And yes, TAA requires v-sync. Not a big deal, I use v-sync anyway.

    So, by enabling temporal AA, I can run it at 4x, and it only has the performance hit of 2x?

    That makes no sense, as CCC tells me it effectively doubles the AA level ie. 4xAA becomes 8xTAA.

    Can anyone else confirm this?

    EDIT:

    Gotta try this out for myself.

    That's exactly what it does. It applies 4x AA patterns to the image, but you will percieve it as 8xAA (hence 8xTAA). So you will see the effect of higher level AA while really applying only a lower level.

    Damn, I never knew about the catch, V-Sync. I hate enabling that as not all my games run close to 60FPS. It is possible to change the minimun TAA threshold from like 60 down to like 30 right?

    I can set the Temporal AA to either 2X, or 3X, which one would most likely created the best quality/performance?
