I did a quick run of one of the layouts I know has the JP sequence issue. I loaded it up 4 times over, and let them all run together. For me, I didnt have the slowdown of the lamps when they were running idly. But I did notice that MFME gets capped at around 10% for the CPU and GPU. Whether this is what is causing the slowdown I do not know for sure. There may be far more to it. I've attached some screenshots inc. the task manager data. Strangely enough, on the JP sequence, when its at its slowest, the GPU seemed to not be in use so much, but the CPU was near max (as much as MFME was allowed to use, 10%). Hope this helps in some way of getting some insight to this issue.
