This absolutely killed my laptop, my CPU load was at a constant 85% while doing NOTHING in FL studio. I spent hours at the end trying to fix a mysterious issue of excessive peaking, and overall this was a bit of a nightmare. It's done now though.
The cost of this is: I put a lot of effort into the drop, but due to the hardly functional state of the project from then on, the intro and whole 2nd half is a bit rushed. I would usually work some more variation in there but this project was already taking almost 2 hours to export as it was and on its last legs.
