Well, most limos nowadays have their most blingy features as paid-for optionals. I know that it's not your job to make it a fast mod, but if we, who don't think it would be cost-efficient to invest on a new computer just for playing Paradox Games (and this mod specifically, since all the other games run just fine), had access to the poor men's APD, it would be just great.
It could take a lot of work balancing and would be time disruptive to make two versions, so I'd really appreciate if you could give a couple of simple modding tips we could apply so we could all enjoy APD as it was meant to be enjoyed, specifically how to overhaul what you think is the biggest issue: inert pops, in case it doesn't alter the game balance too hard.
Maybe even stickying a thread where people would share tips and their mod changes to improve performance of their APD wouldn't be such a terrible idea, but that's up to us, the players. I'll probably make a thread tomorrow.
