Hello
I’m having some strange performance problems, and I wonder if anyone could help.
I’m using pbuffers and render to texture for offscreen renderíng, and then displaying the offscreen buffer “onscreen” by binding it and drawing 2 triangles, filling the viewport compleatly.
This introduces a sigificant performance loss (it pretty much halfens my framerate apposed to direct “onscreen” rendering), and I’m getting frustrated because it seems I can’t figure out anything to do about it.
I know that the context switching between the “onscreen” and offscreen contexts can be slow, but i hope not this slow…
Any ideas??
Thanx for your time
