Hi,
Could you possibly tell me the actual DMX frame rate that can be achieved with ShowXpress in combination with a D512 interface using the High setting for the DMX Streaming Frequency? Is this a fixed rate or does it somehow depend on the speed (and type?) of the host computer? Is there any way to get a readout of the actual DMX frame rate from the software somehow?
Also, would it be possible for you to increase the maximum frame rate by allowing the user to specify a reduced number of DMX channels to be transmitted? For example by limiting the DMX channel count to 256 would it be possible to achieve double the normal maximum frame rate? And similarly by limiting it to 128 channels could you quadruple the frame rate? This would be totally within DMX specs and is considered an acceptable to achieve higher frame rates as pointed out here.
I'm guessing that I'm not the only one who doesn't use or need a universe with full 512 channel capability so if reducing the channel count would somehow open the door to higher DMX frame rates please consider this a feature request.
Specifically I think a higher frame rate might result in smoother fades in LED pars as even with 44 updates per second for a full 512 channel universe the value would have to increase by 255/44= 5.8 on average per update for a fade from 0 to 255 in one second. Although the human eye can be fooled into seeing smooth motion with frame rates >18 it is capable of detecting changes in intensity at much higher frequencies and I think that's what I'm seeing when I do a fade as described.
Thanks,
Arjan
P.S. I know that some LED PARs themselves may also contribute to this phenomenon but I have the impression that with my Puck Q6/W LED pars most of this effect is coming from the limited DMX frame rate with which they are being controlled.
