Sorry, I do not experience this either. That is, running 'osgprerendercubemap'
as well as 'osgviewer cessna.osg' at the same time, both run at my full refresh
rate.
Running osgprerendercubemap twice does give a problem. In some cases, I get this
error:
Warning: detected OpenGL error 'invalid operation' after RenderBin::draw(,)
RenderStage::drawInner(,) FBO status= 0x8cd5
In other cases, the two windows continue updating, but one runs at full refresh
rate whereas the other runs at around 11-15 fps.
But I think that's pretty much normal. I think the video card is pretty much
supposed to be using FBOs exclusively for one OpenGL context, or something like
that. Someone please correct me if I'm wrong. In any case, two OpenGL windows
using FBOs will probably not be useful very often to me, but might be in some
other applications, so if it's supposed to work it should be investigated...
Hope this helps,
J-S
