Slow LED response & (no) 4k USB Grabber - Rpi3

Hi,
RPi + Hyperion alpha build 7.

Using these and this , with this , I experience a laggy/delayed LED update (222 LED’S), not huge but long enough to be distracting and noticeable. Also, i have to downgrade my image source to 1080p to receive any LED output at all.

1) any ideas how to reduce the delay? How/Would adding in an Arduino help?
2) any suggestions for the 4k source problem? Having to downgrade the source is inconvenient (and makes the project hard to justify to the “boss” as we have a 4k source & 4k TV)

thanks in anticipation for any support for this Noob

Ok, so just turned on, LED’S first, then everything else & ipad for hyperion web UI & real time example, only to find the LED’s working correctly (still with the delay, but i’ll work on that). Partly solved, somehow...

Set size decimation to at least 4 in the usb grabber settings in WebUI. This will reduce the delay.
If 4 is not enough, try with 6 or 8.

And this worked nicely, along with some tweaks to the smoothing, thanks very much!

FFS! I spoke too soon... not working in 4k again. :mad:
