[osg-users] Loading problem, OpenVR integration

[Pelle Nordqvist]

Hi Lorenzo, maybe you want to check out this thread:

http://forum.openscenegraph.org/viewtopic.php?t=14222

For me it helped by simply 'parading' all objects in front of the camera
at the start of the simulation, this forces the push to GPU needed,
as long as the data fits on the card.
I don't think there is any other way to really force this push
for a static database.

Cheers,

/Pelle
