I am positive the lag people have been experiencing with your game has to do with the resolution you are using, VX ace games usually don't go beyond 640x480, I don't know what you're using to get around this limitation but it is hurting the performance. Reverting to a default resolution would probably fix it but you might need to manually resize some of the images and text-boxes, so it might not be worthwhile (at least for me the lag isn't that bad and the game doesn't require precise movement so I'm fine with it).
I really like your writing and art for this game and it already has a good ammount of content. Sorry for playing armchair dev, but I think going forward these should be your goals:
1. Fix and balance the main game loop: The core of the game is the kingdom-management gameplay, but right now it all feels very WIP-ish. You have thought of a lot of cool systems for the economy, prosperity and prestige, army variables, etc. But it is hard to get into it as a player until it feels a bit more stable, right now there are bugs with money lending, potential exploits with firing your whole army before the end of the month and then conscripting a new one to avoid paying wages, no significant ways of improving your economy in the long run, recruitment is way too expensive for how little it does, among other things.
I know you are waiting to be able to get a programmer before implementing some of the stuff (like the custom battle-system), but I think people will get more into the game if they can a better taste of what the gameplay is supposed to be, instead of yet another scene that only plays deep into the Duke's questline or the barbarian questline.
2. After making the early gameplay more enticing, I think you should do some marketing and re-work your patreon to promote the game a bit more, add it to the banner, make the page a bit prettier, potentially add rewards for supporters (early builds, WIP art, etc).
After getting those 2 things done you can continue developing the game as you will, I just think those 2 issues are the main ones stopping people from following the project more closely.
