I did. Not 100% sure what I should be looking for? It says system excellent but apparently that is not a real indication? The line is flat but not super smooth, at 25kHz it has small bumps all over, at 100kHz only a few.
At 25kHz I get max variation between 3 and 7us.
At 100kHz between 2.4 and 3.0us on average.
I am running on a Win7 32bit box. My other machine runs on XP. I tried the Vista registry patch but it did not make a difference.
Thinking I should try another PC, maybe see if I still have an XP install...
