Hi Tim, The new data arrives asynchronously out of threads. So I have no chance to relate the updates in any way to the timing of frame() calls. Unfortunately I cannot believe it doesn't matter to osg replacing arrays out of threads eventually while frame() is active. BTW using VBOs results in the following message:
Warning: detected OpenGL error 'invalid operation' after RenderBin::draw(,) RenderStage::drawInner(,) FBO status= 0x8cd5 Am Mittwoch, 24.
