Currently the lighting update speed is really weird
Notice the weird lighting updates on the sails (flicker) and on the water (lingering blocks of shadow and torch light)

Hack devs: literally prove that Roblox Lighting has the capacity to be improved
Roblox: “so you guys want more Terrain updates right”

I need both terrain updates and lighting updates (just got updates for both, thank you roblox gods)
Those two things are mostly made by the same person (zeuxcg). It’s not like they’re two different parties. And “hack” week projects are quite literally hacks. Just because it works on one machine (zeuxcg’s in this case) doesn’t mean it’s automatically ready to be used across the entire platform or that they wouldn’t have to pour hours of development time into it still.

I think it’s just a shame that we see devs’ amazing additions and fixes to Lighting and yet Roblox works on things like Fonts that haven’t even been inplemented yet. The Terrain updates have been pretty neat but I personally stay away from using it.
EDIT: Go figure, constraints just went live. Still waiting on the new fonts system, then.
This looks like its an issue with the way lighting is calculated. I heard that currently the lighting grid isn’t calculated on the graphics card, so I would assume that means there will be noticeable delay in the update of the grid. This combined with the way the grid works would mean you get these weird blobs of shadow that seem to linger around because that section was determined to be blocked from light and hasn’t yet been passed to the graphics (correct me if I’m wrong here).
The good news is that I also heard there may be plans to handle the grid on the graphics card in the future, so a fix to this may already be in the works (confirm?).
The problem is just that the light grid updates once every so often, not immediately every time something changes, so you see artifacts because you have parts dynamically moving over a static grid. Not sure if that has anything to do with being CPU/GPU-bound, because even at the highest graphics level I don’t get high CPU or GPU usage and I still see the slow updates in some instances, so I think it’s just coded that way.
Can you link to what you are talking about in the last sentences?
Arseny’s out for another week or so (vacation) so I’d directly ping him with this mid-August to get his opinion.
We have a lot of developers here all working on pretty cool things. I’m working on VR for example. The fact that I’m making ROBLOX’s core UI better in VR doesn’t hinder any progress on anything else. If it did, we wouldn’t be a very efficient company.
