Max 4.6.2, Jitter 1.6.2b2.
Ive been remotely debugging a multiscreen Jitter patch with a client,
who is running the system on a beefy Alienware Core 2 Duo PC
The PC has 2 video cards, one bad ass Nvidia 7950 with 512Mb ram and
one dinkier monitoring AGP card. The 7950 has a Matrox Triple head to
go attached, while the second card has only one monitor. 4 monitors
Our patch is designed to run on all three screens from the triplehead
at once. When we run our patch *windowed* across three screens, it
runs at full framerate, about 35/40 fps with slab processing,
jit.gl.sketch calls and texturing across all 3072x768 with quicktime
playback, while the other monitor is left for the interface.
If we run the main output (3072x768 on the Nvidia) with the
'fullscreen 1' message to jit.window, our framemrate drops, the
machine is basically unusable until render is halted, we move the
jit.window onto the dinky preview monitor, lower its size, and then
start playback. Back to 40 or so FPS and everything is working.
We can position the window with border 0, and find the pixel
coordinates - but I guess my question is - what is different about
fullscreen 1 on windows with multiple monitors VS OS X? When running
the same patch on a Mac I do not see those issues?
I think we can work around this (we also had multiple monitor slab
issues as reported, and it seems that 1.6.2b2 fixes most of the
issues), but Id like to know.
Is this an OpenGL driver issue, a known Max/Jitter issue, or XP voodoo?
btw : I cannot attach the patch for various reasons - thanks for
