This could of course just be a bug on my system.

Edit: To be clear, in multi display performance mode, the demo runs, but uses Pixel buffers (or PBuffers).
Sorry to revive this thread, but this is the only place I could find reference to a multi-display acceleration/FBO problem.

I'm having the same issue no matter what PC I try it on (same thing happens on Quadro and Geforce). I've tried posting a question on Nvidia's site, but it's been a month with no reply. Does anyone know if they're working to fix this? Should I just switch everything to pixel buffers, or will I have the same problem? Any other known workarounds that preserve multi-display acceleration?

To be more specific, when I use FBOs with multi-display acceleration, the CPU usage skyrockets and everything slows to a crawl.
