I followed the thread and would like to add the following to it:
You are still generating too much disk I/O, as someone already mentioned...
either do some sort of IPC between the two programs, or - if you are unable
to change the image generator's code - read and write the frames from a RAM
disk. There is still a lot of waste in CPU utilization in the latter case,
but at least you would benefit of a greater I/O performance (eating some
memory, of course).
On the other hand, how do you know if the image generator is ready in
producing a frame? You somehow need to flag the other process, if you don't
want to waste even more CPU time (cycling in a loop, waiting for the
image)... IMHO, this means IPC anyway.
Just my 2ct tips...
