So, I’ve been building a game the past week with future lighting enabled and it’s been absolutely fine performance wise, even on max graphics. Since yesterday though the future lighting has been causing really, really, really bad lag above graphics 4 (Nothing had been changed from the day before when it was running fine, at all). My game depends on future lighting as it’s an atmospheric horror game, so I don’t really have the option to revert it to shadow map. Has this happened to anybody else, or has something gone wrong somewhere in my game through a roblox update or something else. It’s not just my pc either, my friends have tried too with both high and low end desktops and they have also had insane amounts of lag.

I am not sure. Sometimes I can play perfectly fine on my i5 laptop (not the most high-end) on max graphics in a future lighting game and sometimes i cannot even play on 2 graphics without lag.
Is that result with the same game though, or different games?
As a follow up, it seems that roblox has definitely changed something with future lighting because even older iterations of the game with less parts etc has the same issues. Not to mention the lighting style has changed with shadows where there wasn’t shadows before.
The same game, when i visit it multiple times a day and notice different performances

Future lighting has a tendency to start bugging out after there’s a lot of shadow physics and lights to calculate for. I think this is an engine bug sort of thing that can’t really be solved. Not sure, just a guess.
It also really depends on if you changed anything in the time between when it was less laggy and when it started lagging. One thing I could guess is that maybe the new reflection maps could be affecting performance as it’s a pretty recent beta feature…?
Nothing had been changed from the day before when it was running fine, at all
Possibly the reflection update, if it was introduced Sunday the 23rd of May?
Try changing the EnvironmentalSpecularScale and EnvironmentalDiffuseScale and see if anything changes, If not it must be something else.
I had both of them set to 1 when it was fine, just changed it to 0 and I’m still getting insane lag and it’s running at about 12 frames per second so I can rule out the environmental editors. Thanks for the suggestion, though.
