Performance drops after spending time in game

Starting up my world I get great performance even as all the chunks are being rendered but after like 30 minutes or so performance steadily starts declining to noticeable levels. I can start at around 100fps and it slowly works down to where at some instances I’m below 30 even if I cap my fps to 60 even with the extra computing power it still drops after everything is rendered. I am running an i5-11400f with a 3060ti on 32gbs of ram (I’ve tried allocating 8-10 gigs) I am running at 1440 but that’s because I have to with the combo I have or I get significantly less performance due to bottleneck I’m running multiple mods to help with performance issues ie sodium, lithium, immediately fast, memory leak fix and others my cpu load is set to low impact and I’m 256 chunks with 8 render. I am running with shaders to help take some load from the cpu

i am using same cpu and rtx 3060 and 16 gigs of ram

Mati•4/4/24, 12:34 PM

and i don't get performance drops

Mati•4/4/24, 12:35 PM

maybe your cooling system is not good.

Mati•4/4/24, 12:35 PM

i also have lot of performance mods

Mati•4/4/24, 12:36 PM

well if i start to move while the lods are still rendering i am getting drops

Mati•4/4/24, 12:42 PM

allocate more ram too

MMati i am using same cpu and rtx 3060 and 16 gigs of ram

Just A GentOP•4/4/24, 12:56 PM

Cooling is not the issue even at 100% my cpu rarely gets above 60-65 never over 70 and gpu isn’t hitting 100% so temps on that stay low. From what I have read in this discord is that allocating to much ram can cause issues

Mati•4/4/24, 12:56 PM

i've allocated 12 of 16 gigs

Mati•4/4/24, 12:57 PM

allocate a lit more bro

MMati i've allocated 12 of 16 gigs

Originally when I first started I had given the game like 16

because I had 23 unused and then I read that and I was like oh I’ll just turn it down. When I get home from work I will bump it back up and see how that goes

Mati•4/4/24, 1:17 PM

where did you read that

MMati where did you read that

Just A GentOP•4/4/24, 1:18 PM

I don’t remember exactly and it might not have been in the discord now that I’m thinking about it. It may have been YouTube comments on videos about DH I was watching when trying to get it set up

majo24•4/4/24, 1:26 PM

Sounds like you might have a memory leak or something like that

Mmajo24 Sounds like you might have a memory leak or something like that

Just A GentOP•4/4/24, 1:30 PM

Well like I said I do have a mem leak fix mod running (I know it doesn’t mean I don’t have a leak) if that isn’t working what else could I do. I had a video mem leak fix mod but it doesn’t work in 1.20.4

MayBike•4/4/24, 2:44 PM

what dh version is this

Just A GentOP•4/4/24, 3:38 PM

Not sure the version of DH but it’s the one that supports iris and MC version 1.20.4

Is distant generation on? Lods will keep generating farther away and eventually use up memory

Are they lag spikes or just average FPS keeps going lower and lower?

That’s a good question that’s something I just learned about this morning and I’m not sure if it is or not I’ll have to take a look. Is it a feature in the most recent version I’m using the version with iris on 1.20.4

MMarijnIsN00B Are they lag spikes or just average FPS keeps going lower and lower?

Just A GentOP•4/4/24, 5:15 PM

Both I get a fair amount of lag spikes and then eventually the fps drops down

SPINZ•4/4/24, 5:21 PM

It’s been a feature

SSPINZ It’s been a feature

I’m new here

TheNewSky•4/4/24, 6:15 PM

Use f3 and look at the memory usage in the top right as you play. I had the issue where, after a while, it would hover around the max memory I allocated causing constant lagging due to the garbage collection.

TheNewSky•4/4/24, 6:17 PM

You can try to use the jvm arguments to make the garbage collector better

TTheNewSky You can try to use the jvm arguments to make the garbage collector better

Just A GentOP•4/5/24, 1:37 AM

What do you mean by that towards the end garbage, Jvm, and garbage collector. I’ve only recently switch from bedrock and modding on bedrock is no where near as complex as Java

TheNewSky•4/5/24, 1:38 AM

It’s not modding per say

TheNewSky•4/5/24, 1:38 AM

If you use the vanilla Minecraft launcher then in order to change how much ram you have allocated you have to edit the jvm arguments

TheNewSky•4/5/24, 1:40 AM

And the garbage collector clears out space in memory that isn’t being used anymore

TheNewSky•4/5/24, 1:40 AM

So if you allocated 12GB Minecraft might use up all 12GB given to it and then clear out the stuff from memory that it isn’t using anymore

Just A GentOP•4/5/24, 1:53 AM

So does it clear it out itself or is there something I can do or do I just throw more ram at it

TheNewSky•4/5/24, 1:53 AM

You can change its behavior to make it work better using the arguments

TheNewSky•4/5/24, 1:53 AM

I can paste the ones I use in a bit

TheNewSky•4/5/24, 1:54 AM

But it will only help if the memory is what’s causing the performance drop

Just A GentOP•4/5/24, 2:00 AM

Got it where do you go to change these is it in the place where you allocate cause I’m completely lost

So obviously I need to check the mem in game but is this a normal thing to have to do or is it just random from pc to pc sort of thing @TheNewSky

TheNewSky•4/5/24, 2:22 AM

Depends on the mods you have

TheNewSky•4/5/24, 2:22 AM

I never had to do it until I downloaded a ton of mods

TTheNewSky Depends on the mods you have

Oh makes sense I’ll look into and see what happens
