I’m encountering a problem when running vvvv: Every 3-500ms or so, vvvv stutters a bit. This occurs even (and can be nicely observed) with a super simple patch of just a quad translating left to right - the expected motion is supposed to be smooth, but it is not, there’s a little jerk one or two times a second, not totally regular.
I have a hard time diagnosing it. It occurs irrespective of single or dual screen, if multiple renderers show the same content (initially I suspected some weird sync issue with external monitor).
Renderer presentation interval does not have an influence, Main loop time mode Filtered or Increment show the problem in a more pronounced way.
I also fiddled with graphics driver settings, does not seem to do anything.
I don’t know if there are background processes running causing this, but I have nothing out of the ordinary running I think. Virus scanner is deactived, doesn’t help.
This problem was present in earlier versions of vvvv, too, but I haven’t been using it so heavily lately, and coming back to it it seems to be more pronounced (can’t swear this, though).
Ah yes, I’m using b27.2, on a Win7 64bit laptopt with an Nvidia Quadro FX770M chip, driver version 296.83.
So, does anyone have an idea what this could be, or better how to fix it? It’s pretty annoying if you present slowly moving graphics. :-(
