I can somewhat reproduce: java version is making it worse.
the torch and other light sources seem fixed.
I also cannot reproduce on the latest.
I appreciate you giving a better test environment. Note I am using java 22.0.1 instead of 21.0.3:
in plain minecraft I get slightly less fps drop(40 to 60 which is around a 50% and in yours you shared around 85%)
with a datapack adding custom noise function without all my customizations I get ~25(20 to 30) fps drop
with a datapack adding custom noise function and with all my customizations I get ~0(0 to 5) fps drop
Let me know if any more info would be helpful.
can only consistently cause the GPU increase. Am I missing something?
think I can confirm, it seems related to: MC-250246. And if individual is willing, I would assign Les3awe.
reason I asked it because some people get unofficial Minecraft servers thinking its official.
IDK why it was in vanilla logs, when it was mainly a fabric issue. Although the sculk sensor showing up as unknown is annoying.
can you see if this occurs during day as well?
cause I am not sure if this is truly vanilla/non-modified can you open f3 screen and take a screenshot?
could be something else I am not being easily able to reproduce it.
Java version 8 is likely the issue, if not it is a device specific issue shown at MC-151530
Connor Steppie, this is already being tracked under MC-5417 is what I think mojang is saying.
ent and AgentM try my solutions, see if they work.
incorrect version tag stating 1.21, it stops at 1.20.2 mostly.
can others verify I know its happening I just want to know if its on just my pc?
not saying it should be reopened just stating that I want to have it actually thought about before deciding to set as invalid.
Mojang please do not default post a invalid on this.
Can Confirm, and MrMuskle they are different issues, ArsiTheFox can you give a better description of the issue so they can see its different.
