Yes, but I don't have any good solution to fix it for now 😕

The larger the screen, the laggier it gets (especially on 4k screens).

This is because more tiles are loaded, (+ seas tiles which are animated and thus cannot be cached) Assuming you're on a laptop with somewhat regular size, you'll load something like 11 chunks x 6 chunks with each chunk being 16x16 tiles, so around ~15000 tiles are rendered 😅 (somewhat doubled when sea is displayed + we're in a browser environment so it don't get as efficient)

So it's kind of miracle that currently it works. There some cacheAsBitmap optimization when a chunk is fully static but I'm pretty sure it's not enough. I don't want to use pre-rendered chunks though, as the aim is to later make a "live rendering" including wandering peoples, creatures, water reflection, handling upper layer correctly, etc.

Hopefully one day it'll be improved though 🙂

Whole project was migrated to deno and deno deploy, and switched to vanilla html instead of using Vue, now only dependency is pixi.js

It should be a lot faster now!
