I am unable to look through which of these hundreds of mods is causing the issue.
Please help pinpointing which one is causing the problem, otherwise the issue is non actionable and closed.
(Just for reference: not all modpacks experience this issue)

I understand, but i dont know which mod is causing the problem... I am trying to figure out but i am not a dev... I thought you could help me with this... I Saw some people with this problem on the comments of the mod (But they think that simplyswords are causing the lag).

I cant tell you which one is causing this problem.
Do you think the performance mods are causing the lag? do you have any idea of what i can test to check which mod is causing this? (I would try any)

[ZsoltMolnarrr]

To pinpoint which mod is causing this, try disabling your mods manually until you see the error gone, in a binary search method, (binary search will take the least amount of action).

I have zero idea which mod is causing this problem. Most usual candidate is Optifine. Sodium and Iris don't cause this.

Thanks!

1 by 1 takes lots of time, I recommend binary search. https://www.youtube.com/watch?v=MFhxShGxHWc

I finded!
Its "Emotecraft". When i remove this mod, the game starts to works properly.

[ZsoltMolnarrr]

Thank you for the information!

[Zaatch]

Thank you for the information!

Thank you for the patience

Using the following mod versions I am unable to reproduce the issue in single player:

Better Combat [Fabric & Forge]
daedelus_dev
bettercombat-fabric-1.7.1+1.19.jar

Cloth Config API (Fabric/Forge)
shedaniel
cloth-config-8.2.88-fabric.jar

Emotecraft (Fabric)
KosmX
emotecraft-for-MC1.19.2-2.2.5-fabric.jar

Fabric API
modmuss50
fabric-api-0.76.0+1.19.2.jar

MC Dungeons Weapons
chronos_sacaria
mcdw-5.0.11-1.19.jar

playerAnimator
KosmX
player-animation-lib-fabric-1.0.2.jar

Sodium
jellysquid3_
sodium-fabric-mc1.19.2-0.4.4+build.18.jar

Are you sure you have updated all mods to the latest version?
Is this effecting multiplayer only?

[Zaatch]

This happens on Single Player too
I am using 200+ mods, but only when i remove "Emotecraft" the game starts to work properly.
I just used AT Launcher to update every single mod i use, and the problem continues...

[ZsoltMolnarrr]

What version of Emotecraft are you using?

[Zaatch]

Same as you, 2.2.5

[Zaatch]

i tested with the beta too, 2.2.7

[ZsoltMolnarrr]

Can you reproduce the issue with the release version 2.2.5?

[Zaatch]

I was using the 2.2.7 version before.***

Reproducing:

without holding two-handed weapon

holding two-handed weapon

holding one-handed weapon

My new tests presents:
277 Without holding two-handed weapon
217 holding two-handed weapon (60 fps loss)
273 holding one-handed weapon (4 fps loss / no problem)

[ZsoltMolnarrr]

I was still unable to reproduce the issue with the mentioned mods.
If you install Better Combat, Emotecraft, Sodium and Iris only, does the issue occur?

[LokiLingerin]

it looks like it has something to do with player models, im using shoulder surfing and first person player model + alex's armoury and the issue also is ocurring. i believe it may have something to do with the hands as well, since with two handed weapons the issue is most prevalent, it also happens when atacking a single handed weapon

single handed weapon not atacking

single+atacking

2 hand not atacking

2 hand atacking

[LokiLingerin]

plus it also seems to happen when using an emote, its probably an incompatibility with player animator (?)

[ZsoltMolnarrr]

I am still unable to reproduce this issue.
Please specify the minimal mod setup, with a specific scenario to reproduce it.

[luan-digital]

Hello,

I was having the same issue, and it's very bad when playing with friends on my server, as whenever someone attacks, my FPS will go down significantly. After doing some tests, it appears that the issue is indeed something related to Emotecraft, but this problem is more noticeable in third person, wearing armor and when shaders are enabled with Iris.

Here's a little video I recorded showing how the FPS drops from around 90 down to 60 when attacking in third person wearing armor, with smaller drops without amor. Note that the armor is invisible due to another mod, but I also recorded another video without many of my mods and there's still a drop from around 100 fps to 90 when wearing armor versus no drop without armor (10 fps isn't a big deal, but the frametimes get all messed up, so it's very noticeable. I think this number is also smaller because I recorded in a superflat world).

Both videos were recorded in Minecraft 1.19.2 Fabric 0.14.22 and 0.14.23.
Mod list (from the second video, where there are way fewer mods but the issue is still present):

• Better Combat 1.71
• Better F3
• Cloth Config API
• Concurrent Chunk Management Engine
• Emotecraft 2.2.7-b
• Enhanced Block Entities
• Entity Culling
• Exordium
• Fabric API
• FerriteCore
• Forge Config API Port
• ImmediatelyFast
• Iris Shaders 1.6.10
• LazyDFU
• Lithium
• ModernFix
• More Culling
• No Chat Reports
• Puzzles Lib
• Smooth Boot
• Sodium
• Starlight (Fabric)
• Trinkets
• Very Many Players (Fabric)
• playerAnimator 1.0.2

[ZsoltMolnarrr]

Thank you this is useful information, however more specifics are needed.
Does the problem happen without EmoteCraft?
Which is the absolute fewest set of mods to reproduce this problem?

[luan-digital]

Hey, thanks for the reply. I did some other tests now and this only happens with EmoteCraft installed, and I was able to reproduce the issue with this minimal set of mods as well:

• Better Combat 1.71
• Better F3 4.0.0 (used only to keep an eye on the frametimes)
• Cloth Config API 8.3.103
• Emotecraft 2.2.7-b
• Fabric API 0.76.1
• Iris Shaders 1.6.10
• Sodium 0.4.4
• playerAnimator 1.0.2

The shaders I tested this with are Complementary Shaders Reimagined, Nostalgia and Solas.

I think it's important to note again that the issue seems to get worse when the player is wearing armor, and that I only had issues in third person or when another player is visible while attacking.

Hello everyone, I join in the discussion of this issues. There is a modpack with more than 200 mods on forge (writes one of the modpack developers). The modpack has all these mods:

• Better-Combat-Forge-1.7.2-1.19.2-FC.jar
• emotecraft-for-MC1.19.2-2.2.7-b.build.50-forge.jar
• API-player-animation-lib-forge-1.0.2.jar
• firstperson-forge-2.2.3-mc1.19.2.jar
• API-bendy-lib-forge-2.1.1.jar

Embeddium is used instead of Sodium.
Some players (not all) have strong FPS drawdowns when they pick up a weapon (even an ordinary sword or axe) or when interacting with it. Surprisingly, the issue may not occur immediately, but after a while.

I will do the testing and write about the result later.
(Sorry for my English)

[K0rS1z]

Tests have shown that removing the mod "API-bendy-lib-forge-2.1.1.jar " solves the issue.
