You guys really need to reread my earlier post and read about temporal antialiasing methods and implementations and their faults. Yes TAA looks worse than msaa especially depending on the software and its implementation of said taa.
Different drivers most certainly can cause different results. However one thing is for certain...turn on taa and any time you put a 3e rendered scene in motion it will be susceptible to shimmering and flickers depending on the configuration of input turn speeds and motion matrix math.
