Thank you so much for posting about your performance experience. This is hugely helpful to me.
The performance enhancement I landed last week is retroactive, which is bad news: it means there’s not much for you to do yourself.
I see the map is just one big area, and I can see why you don’t want to split it up. I wouldn’t want to either.
I have two pieces of good news, but they’re really lukewarm if anything:
- I can reproduce the problem: your map is slow on my computer. This is unusual as most of the performance issues people report don’t appear for me on my computer (I’ve got a modestly beefy machine). I’m going to download it into my dev setup and play around with it. I may be able to figure what’s slow and make it faster quickly (maybe even in time for your game). I’ll try and let you know what happens from that, but the most likely result is that I’m not able to fix this for you.
- Performance is the highest priority issue at the moment, and it’s the bulk of the work in this coming month’s roadmap. It’ll take some time to really get the improvements nailed down, but Shmeppy will be fast enough for big maps like these (and way bigger) before long. Like, I think it’s safe to say that 2 months from now Shmeppy will be plenty fast.
I wouldn’t bother trying to use Shmeppy with your party tonight 
(unless I’m able to push a change to fix the problem today). I think it’ll just be frustrating. If it’s laggy right now, it’ll only be worse with tokens (especially token labels).
Shmeppy is still just not fast enough.
