I am a beginner with Jitter and I would like to know if is there a way

Monitor 1 ---> patcher and small preview window

The second question is about the graphic card. On my desktop PC

(Pentium IV 3200 HT disabled, 1 Gb RAM), I did a patcher that creates

shapes in realtime processing external audio. The problem is that when

I have a small jit.window the visuals seem (almost) realtime, while

turning to fullscreen mode the latency rises up to look really out of

sync. I want to know if upgrading my GPU ( an old Matrox G400 32 Mb)

the situation will get better and if you have advices on a good GPU to

Hi list,
I am a beginner with Jitter and I would like to know if is there a way
under windows to have an external monitor in fullscreen mode
displaying what I am creating in the primary monitor of my laptop, for
live performances. The setup would be:

Monitor 1 ---> patcher and small preview window
Monitor 2 ---> fullscreen render window

The second question is about the graphic card. On my desktop PC
(Pentium IV 3200 HT disabled, 1 Gb RAM), I did a patcher that creates
shapes in realtime processing external audio. The problem is that when
I have a small jit.window the visuals seem (almost) realtime, while
turning to fullscreen mode the latency rises up to look really out of
sync. I want to know if upgrading my GPU ( an old Matrox G400 32 Mb)
the situation will get better and if you have advices on a good GPU to
use with Jitter, or if I need to do just  some performance tweaking on
my current setup. Thanks in advance,
Alessandro

absolutely.  look at jitter tutorial #38.


Thanks, can you answer my second question though?

I will note that upgrading to a recent generation ATi or NVidia card 

is most likely going to give performance benefit in most situations 

over this older Matrix card, since their pixel fill rates are 

significantly faster (which sounds like the issue for you if it runs 

fast in a smaller window, though not as fullscreen). One potential 

possibility with your current card would be to perhaps to resize the 

output monitor to be lower resolution (say 640x480), if you haven't 

tried this already. the jit.displays object could be used to this end

Newer cards are anywhere from 2000-15000M Pixels/sec fill rate (4-30x

I would be really interested to know the issues related to

- how jitter handle that (as far as openGL is concerned)

- how memory and processing is shared among the various cards

has anyone tested the new Power Mac G5 with multiple
graphics cards and 8 displays?

I would be really interested to know the issues related to
this setup related to:
- how jitter handle that (as far as openGL is concerned)
- synchronisation of the screens
- how memory and processing is shared among the various cards
- any other interesting issue...
