[QUOTE="Skymaster, post: 129635, member: 36626"] Playback of a pre-rendered sequence requires very little processing power. It's reading the channel data from the FSEQ and spitting it out to the lights. This is why a small-board computer like a rPi works well for this. Creating the sequence in xLights, however, needs much more grunt work, because this is what takes the effects and layout and has to compute frame by frame what the RGB values for every pixel are. Now, depending on the sheer number of lights and channels, thats where the processing power ramps up. Matrixes and panels have very high channel counts and are where alot of grunt is needed to generate the frame data. I have around 18k channels in my display, and the same again in my TuneTo sign. So not particularly large. Sequences take up to 5-10 seconds to render on 2 year old mid-spec desktop, and about 15 seconds on a 7 year old laptop. But if you had hundreds of thousands of channels, this could blow out to minutes on the same hardware. So, YMMV. You'll get suggestions that you must have the latest Mac Pro M2 CPU and things like that because it's more optimised etc, but those things cost a fortune, and honestly, the hard-on for a few seconds of lower render time is certainly a driving factor there. You can certainly use any machine, until your show gets so massive that it just refuses to render on a machine. My suggestion is don't go buy something crazy until you get frustrated or can't render, certainly not if the only purpose is for the 1-2 months of a year that you are sequencing. Use batch render - hit the button, come back in half an hour and you're all done :) [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
