> Q1.-Q3. These can only be answered with profiling. I've seen compositions that can render thousands of frames per second (so you could do ~30 screens from a single machine at 30 fps, assuming it was possible to get that many video cards, which isn't the case), and I've seen compositions that struggle to render 1 fps -- your composition(s) will likely fall somewhere between those. If the landing point is high (>200fps), you could drive 2 screens, maybe 3 (and maybe 4 if you're ok with 30 fps instead of 60).
I'm not sure which GPUs can be doubled-up these days, so hopefully someone else knows that (I'm going to randomly guess 4 to be the maximum number of outputs, assuming each graphics card has 2 outputs, and you can fit 2 in a box. I don't think more than 2 graphics cards/machine are possible, but I could be totally wrong). > Q4. > Who on this list with the appropriate Cocoa/OpenGL/Wizardry skills might be > interested in being hired to help make something like this happen?

Smokris and I did exactly this for a few shows recently (within the past 18-24 months). He can likely chime in with more details. _______________________________________________ Do not post admin requests to the list. They will be ignored.
