Updated series. The debug patch is dropped, a r-b by Nicholas is tacked onto patch 1/3 and patch 3/3 has the locking fix that Nicholas proposed. In terms of testing 3/3 didn't change anything for the better or worse, observed behaviour on retested DCN-1 and DCE-8 is the same. Patch 2/3 is identical. For reference i made a little git repo with a cleaned up version of my test script VRRTest.m and some pdf's with some plots from my testing with a slightly earlier version of that script: https://github.com/kleinerm/VRRTestPlots Easy to use on a Debian/Ubuntu based system as you can get GNU/Octave + psychtoolbox-3 from the distro repo. Explanations in the Readm The following plots illustrate how patch 2/3 can sometimes help to make transition to BTR a bit smoother min VRR was 25 Hz or 40 msecs in this test case on DCE8 and 30 Hz or 33 msecs on DCE11.
