I’m not exactly sure what vsync does, other than turning it off speeds up performance by at least 100%.
but I did notice that the performance panel and the tab (and the exit confirm dialogue) are drawn on the right screen when vsyn is off and you’re in horizontal span.
Is this an unavoidable byproduct of having vsync off or a problam that Derivative can fix?

vsync decides if the app needs to swap its buffers in sync with your monitors refresh rate. With it off the buffer will swap as quickly as possible (thus the higher framerate), but you will notice horizontal tearing of the image.
The positioning of dialog boxes has nothing to do with vsync though, thats strange. Something to do with your nview settings I think?
yeah it’s only happening with vsync off, on two different computers, on two different graphic cards (7950 GTX) - and (8800M GTX)
it must be disclosed that I’m using modified nvidia drivers from the laptop2go site because Touch can’t deal with dual monitors and many laptops have drivers modified to not allow the horizontal span.

What happens when you tell nview to specifically open dialogs on the left monitor?
Do the custom drivers come with nview?
mmm… I do have to enable the NView Desktop manager for me to have that option, which is something - admittedly a few years ago - Jarrett advised me not to do so as not to lose performance speed (maybe I misunderstood him).
Anyway I did that, and so far it has behaved correctly. Now of course Houdini is misbehaving with vsync off, so I’m going to make it application controlled and try vsync off in my start table.

nah there’s no performance issues with using nview. Maybe you’re thinking of ntune?
Although a few years ago things may have been different. At any rate is safe and good to use now. (ntune is still bad)
mmm… I am noticing even with Houdini that now certain sections (the menus, not the windows) are not refreshing all the time, even though I turned vsync off in nview. Maybe it’s the directive of where to open the panels, I’m not sure. Maybe it’s once again my card (I haven’t - nor I won’t try - houdini on the other computer I’m setting up, it doesn’t need to be installed).
I’ll keep you posted if I notice more anomalies, it’s certainly a trick to find the right performance/quality balance.
It would actually be nice if you guys could post the Nvidia settings of your preference to this forum, with filtering options, etc. so that others may benefit as well.
thanks,
