I won't argue with that theory (because I agree with it).
But, in Standard mode with AMP off I had identical results when compared to Standard mode with AMP on High.
Perhaps the processing is still taking place and producing identical input lag but it is just not inserting the extra frame(s)?
I also could only assume that Low, Med and High are different in that each setting increases the amount of frames inserted each second?
High inserts 60 extra "calculated frames" each second
Medium inserts 40 extra "calculated frames" each second
Low inserts 20 extra "calculated frames" each second
Off inserts 0 extra "calculated frames" each second
The lag time created by this process (while in a normal mode) may be present regardless of whether the "calculated frame" is inserted or not.
To me this would make more sense based on my understanding of AMP AND the test results.
It would also make sense that game mode and PC mode remove this processing/circuity from the signal processing path all together and therefore reduce the input lag.
