It's a little hard for me to get into other people's caps when there are no comments at all.
From what I've figured out, you should have a closer look at event 17 and its subevents 18+19 and at event 20 with the subevents 21+22.
When I put in TimeDelta there, it would act the same in VSYNC and UNLIMITED mode. At least it appeared to me that way.
