one caveat: > [@Mapping LED Bikini](https://forum.electromage.com/t/mapping-led-bikini/1156/7): > > Okay got it mapped and synced properly now, thanks everyone for the help! I did have to add the fake pixels at the end of each map, but only adding 2 didn’t work timing-wise. For proper timing sync they both need the same number of total pixels. Basically the same image and same map coords but reordered. So the map for the top is A, and the map for the bottom is B. Now the top PB map has the A map then the B map, but the bottoms start at B then go to A. It’s comically simple the solution wa… just came across this, as I was reviewing older posts looking for code… In your case, having 13000 pixels in each map/PB might be too much… but the goal is the same number of pixels, I think, so the CPUs are working with about the same amount of data each render cycle… so 13000/4 is roughly ~3000+ pixels, but do try to at least keep equal amounts on each PB… You’re going to have to play with timing to get it to work right. Again, non-trivial # of pixels, so the syncing of multiple PBs on that scale will take some work/experiments. Keep us in the loop. --- _[View the full topic](https://forum.electromage.com/t/expected-framerate-13000-leds/1382)._
