[osg-users] Graphic pipeline latency question

[Claudio Arduino]

Hi to All,

thank you for help, we have tried with Quadro board and the orange bar is
now ok but we are still measuring two frame of latency, the distance marked
with green color in the image screen.jpg attached at this message. The first
orange bar is within the frame 1 time slot (we expected it within the frame
0 instead, somewhere within the red marked time interval): does this mean
that the graphical istructions of the frame 0 are processed by the GPU
during the frame 1? If so, it is clear why the color change in the screen
appears only in the frame 2, at two frame of distance from the "rotate
model" istruction and from signal sent to serial port (sent at the begin of
green bar)

We think that this problem of latency is coming from OpenGL drivers
directly, but we don't know how we can solve it...
if you have some suggestions....

thanks
