i updated the mod based on the screenshot i just sent and i get much more performance now i did install ferritecore at the same time so i'm not sure if that helped at all EDIT: nevermind i guess, it only updated after a restart, so i was using 2.1.0-a in that screenshot. I'm finding some strange results. If i open mc for the first time and load up a world ive already been in at 32 medium, i get 160fps+. if i then change my settings to 128 high i get 45fps. but if i then go back to 32 medium i only get 110fps, and if i exit to main menu and load again at 32 medium, i only get 75fps. does anybody have a clue on what's going on here? can you replicate this? have you had this issue before?

what the f ive seen that before you need some staff member on here to look at it, a few of them have seen this before as well switching back and forth between render distances destroys performance for some reason

Could be world gen starting and stopping affecting fps?
Aggressive Combo
well how would i fix this? it's really annoying i don't want to restart the game every time just so you know, turning off lod generation doesn't improve it at all

Set render distance to something high, like 512, wait for that to load, and then set your render distance back to 256 and turn off distant generation Oh Then I don't know
Aggressive Combo
coud you tell some other staff to see if they can replicate this?
Puhpine
Puhpine2mo ago
I'll test it in a few hours
Aggressive Combo
alright, keep me updated
Aggressive Combo
here, you can see exactly what i'm experiencing

Distant generation can take a minute to fully stop. Can you check if it's really not the issue?
Aggressive Combo
you can see in f3 at the end it says world gen: 0/0 it's finished

Oh yea true
Aggressive Combo
and no, it does not get better if i wait
Timo of the Timoing
ok so someone else used nightly they had this same starting stopping problem
Timo of the Timoing
their log
Timo of the Timoing
definitely a problem with that nightly build had the same thing it just gets this horrible stuttering problem, then goes to 0/0 and just gets in a loop for a while then it works again (??) it queues a renderer cleanup then it instantly decides to do that cleanup then it gets occupied doing that and just quits doing LoDs until it gets out of that loop
Aggressive Combo
i was not using nightly in this example though. i was using 2.1.0-a
Timo of the Timoing
i've not seen this happen prior to 2.1.0
Aggressive Combo
yeah, i WAS using 2.1.0 try to replicate this with the stable build puhpine is going to try to replicate it when he can
Timo of the Timoing
i have no clue what triggers it you?
Aggressive Combo
my issue? i sent a video https://discord.com/channels/881614130614767666/1249090448828399668/1249261209992040461 EDIT: Using a completely clean installation with only the fabric api and dh, this problem does not go away.
Aggressive Combo
that's something completely different...
Timo of the Timoing
ok gl
Aggressive Combo
im just waiting for someone to replicate this because it makes it unusable for me

what mod loader and MC version? generating some LODs now
Aggressive Combo
You can see that on the top of this thread 1.20.6 fabric
Puhpine
Puhpine2mo ago
sorry, forgot
Puhpine
Puhpine2mo ago
i did not notice the same issue
Puhpine
Puhpine2mo ago
it always jumped back to 320 to 330 fps whenever i switched back to 100 lod distance and 400 when i switched to 32
Aggressive Combo
that's weird. did you have any other mods or was that a clean installation? you didn't leave the world and join back though
Puhpine
Puhpine2mo ago
clean install oh was that required to reproduce it? oof
Aggressive Combo
i mean it definitely made the problem worse
Puhpine
Puhpine2mo ago
but you already saw the problem when you just switched between lod distances right?
Aggressive Combo
yes, but it got much worse when i left and joined the world as you can see in my vid
Puhpine
Puhpine2mo ago
yea thats true
Aggressive Combo
can you try that?
Puhpine
Puhpine2mo ago
i kinda deleted the instance because im smooth brain so ill need to regenerate the lods so it might take some time
Aggressive Combo
alright
Puhpine
Puhpine2mo ago
same story
Puhpine
Puhpine2mo ago

Aggressive Combo

Maybe its related to AMD?
Aggressive Combo
who knows, probably could you get some staff here or someone that knows a fix? it's very frustrating if you know someone with a similar setup lmk
Puhpine
Puhpine2mo ago
me and marijn are staff 😭
Aggressive Combo
i know you are
Puhpine
Puhpine2mo ago
if i see someone with a similar issue i will let you know
Aggressive Combo
alright thanks @Puhpine (GMT +2) just wanted to let you know that I fully reinstalled/reformatted all my drives (including windows) and that issue still persists i haven't tried 2.1.2a yet im probably gonna put it on gitlab

Sucks that you still have the issue. As you're the only person still that I've seen with this problem I doubt it's easy to fix
