I don't quite get what is "multiple JFrames with a single buffer
strategies". createBufferStrategy() API is per-Window, so if you have N
windows, you also have N BufferStrategy instances.
would like to know how I can determine how much memory would be required
just to render the buffers for those frames in Windows XP/7. The setups
will most likely have 2-6 monitors and window sizes can be anywhere from
a small window, to a maximized, to stretched across 6 monitors. Given
total desktop resolution, window sizes, window positions, etc, is there
a good strategy I can use to approximate with maybe 70%+ fidelity how
much ram will be needed to render the windows? I would like to keep the
ram requirements to the bare minimum (flexible but the less the better)
needed without hitting any sort of thrashing (if that is an issue).
Why do you need this information? AWT/Swing apps don't have direct
control over BufferStrategy: you can draw to it, but cannot control if
it uses video memory, system memory, when it gets lost, etc.
Adding 2d-dev alias to CC as BufferStrategy class are mostly Java2D objects.
Thanks,

Can anyone give any either formulas or rules of thumb when attempting to
get the numbers? I’ve seen performance where strong references would be
= max resolution under various cases, some where each window (some off
screen) would take up max resolution size (6 monitors) etc. However this
is all non-scientific memory profiling so I don’t know if I have a
correct understanding of when the buffers are set to what size.
