[QUOTE="Jong, post: 610139, member: 104040"] One of us is missing something here though guys (quite prepared to accept it is me!). What you seem to be trying to do is use Reclock vsync correction to fix drift, but as my long rambling, possibly incoherent, post above said is that as soon as you turn on your vsync correction you break Reclock's feedback loop. Reclock adjusts the "raster offset" by measuring EOP. It relies on EOP occurring, on average, a fixed time after "raster offset" (asynchronous to vsync), but when the Presenter fixes SOP this link is broken. It wont work. For Reclock to do what you want it would need to have another point of reference that either was your "raster offset" or is at least related to it and for that you would need the special API you have discussed. Or are you trying to do something else altogether?! :ooops: [/QUOTE]
