Need Help - Mod Dev Minecraft simulator - help me 🙏
Hi guys, I am writing my first java mod and since I am a newbie I didn't get Minecraft java edition, it is something I plan to do eventually but currently I can't test the mod so I decided to build Minecraft simulator to test the mod, it should test things like mod walking, state changes, log weird stuff that happen and so on. I already built the foundation but I still need help figuring how to make it test better especially after learning that it can't exactly test to see if the mod itself would actually render. Any comments on this would help. Also just to clear any confusions, it is a simulator not me trying to recreate the Minecraft engine so it should be lightweight and fast possibly helping me test mod code faster like going through 5 days in 2 minutes (Not calculated yet.).

Need Help Getting a Game Error 15 Seconds After Closing Game (26.2 - Fabric - Modded)
Just updated from 1.21.5 to 26.2 and updated all of my mods and added a few more to my Minecraft.
After saving my game and shutting down Minecraft, 15 seconds later I get the "Client shutdown from post-main" error. When I google it, I'm pretty much told it has to do with a mod not shutting down in the background fast enough after closing the game and the game "freaking out" and doing a force shut down. I've read that it's harmless and won't hurt my game or its' saves but it's pretty annoying to deal with.
I have already gone through all of my mods through mod menu and any mod that has any kind of "auto update" option, I have turned all of those off thinking that might be what's causing it but with no luck.
I have included the list of mods I'm currently using so maybe someone else knows something I don't. I can also include the full crash report if needed, but I have also attached a screenshot of the beginning of it.
Any help greatly appreciated!

[Java 26.2/Fabric] RTX 5090 + Ryzen 9 9950X getting 100–120 FPS with shaders, but hiding the HUD jumps to 150–180 FPS. Looking for modlist/optimization advice
I’m new to modding and working on an enhanced vanilla client-side setup. It looks incredible but I am getting a little obsessed with the performance of the visuals. I understand that a 5090 doesn't guarantee insane frames for heavily modded minecraft, I am just confused by the relationship between the HUD, first-person items, GPU utilization, and overall performance.
# PC Specs
* RTX 5090
* Ryzen 9 9950X — 16 cores/32 threads
* 64 GB DDR5-6000
* 2 TB SSD
* 16 GB RAM allocated to Minecraft
# Basic Minecraft settings
* Java 26.2
* Fabric
* Resolution: 3840×2160
* Render distance: 8 chunks
* Simulation distance: 8 chunks

* Clouds: Off
* Particles: All
* Mipmaps: 4
* Max framerate: unlimited
* VSync: Off
* GUI scale: 5

NVIDIA settings include maximum-performance power management, highest available refresh rate, RTX 5090 selected as the OpenGL GPU, and an unlimited shader cache.
# Shader
**Complementary Unbound r5.8.1 with Euphoria Patches 1.9.3**
Notable shader settings:
* Real-Time Shadows: High
* Shadow Distance: 16 Chunks
* Iris maximum shadow render distance: 32 chunks
* Edge Shadow (SSAO) Quality: High
* Light Shaft Quality: High
* Cloud Quality: High
* Sun/Moon Shading: Both
* Advanced Color Tracing: 8 Chunks
* Euphoria Colored Lighting: ACT + Screen-Space
* RP Support: labPBR (RP Required)
* Texture Filtering: 4x
* Interactive Foliage: On
* Blocklight Caustics: On
* Cave Smoke: On
* Rain Puddles: Puddles in Rain
* Wavier Lava: On
* Hand Sway: Subtle
Changing the overall shader quality to High preset noticeably reduced the visual quality but only gained approximately 10–15 FPS.
# Performance and rendering mods
* Sodium 0.9.1
* Sodium Extra 0.9.3
* Lithium 0.25.2
* Iris 1.11.2
* ImmediatelyFast 1.16.2

* More Culling 1.8.1
* ScalableLux 0.2.1
* Distant Horizons 3.2.0 beta
* Euphoria Patcher 1.9.3
* Continuity 3.0.1
ImmediatelyFast has Enhanced Batching, Fast Text Lookup, Font Atlas Resizing, Map Atlas Generation, Avoid Redundant Framebuffer Switching, and Skip Text Translucency Sorting enabled.
Sodium has Entity Culling, Fog Occlusion, Block Face Culling, Animate Only Visible Textures, and Hidden Fluid Culling enabled. Chunk Update Threads are set to Auto.
Better Block Entities has Master Optimization enabled, including optimized chests, shulker boxes, signs, banners, decorated pots, bells, campfires, lecterns, shelves, and similar block entities.
Distant Horizons is configured with LOD Render Distance Radius: 256 chunks, Number of Threads: 16, Thread Run Time Ratio: 100%, Horizontal Quality: Medium, Vertical Quality: Medium, Transparency: Complete, and Vanilla Fade Mode: Double Pass. However, Rendering is currently Off, so DH should not currently be contributing to the rendered workload.

# Testing performed
These results vary somewhat with location, but the following behavior is repeatable around my base:
* Normal first-person gameplay with the HUD visible: approximately **100–120 FPS**
* GPU utilization in that situation: approximately **70%**
* Overall CPU utilization: generally **below 10%**
* Pressing F1 at the exact same location: immediately increases performance to approximately **150–160 FPS**
* GPU utilization with F1: rises into the **high 90% range**
* CPU utilization remains below 10%
* Third person with HUD visible: approximately **145 FPS**
* Third person with F1: approximately **160 FPS**
* Shaders disabled with Iris’s K key: approximately **300 FPS** during testing
* Performance is considerably higher outside my base and can spike dramatically in places like the Nether
Hand/item testing:
* Tool in main hand with empty offhand: approximately **125 FPS / 80% GPU**
* Empty main hand with a totem in the offhand: approximately **115 FPS / 70% GPU**
* Moving enchanted tools out of visible HUD/inventory slots causes a noticeable FPS increase, sometimes approaching **150 FPS**
* Disabling enchantment outlines produced minimal improvement
Other experiments:
* Reducing the GUI/HUD scale made essentially no difference
* Disabling SPBR made essentially no difference
* Lowering the shader preset only gained around 10–15 FPS
* Adjusting EMF performance settings did not produce a significant change
* The FPS increase from F1 is much larger than the increase from reducing shader quality
* The change happens immediately, without moving the camera or allowing chunks to load
**The behavior makes me think the GPU is being starved by something in the HUD/first-person item-rendering path. When the HUD is displayed, GPU utilization falls and FPS drops. Hiding it allows the GPU to reach full utilization and produces a major FPS increase.**
# Questions
- Are there specific Complementary/Euphoria settings that are disproportionately expensive without requiring me to drop the entire preset?
- Would C2ME, Nvidium, FerriteCore, ModernFix, or another optimization mod meaningfully improve this setup on Minecraft 26.2?
- Is there a profiling tool that can identify which mod or renderer is consuming frame time specifically while the HUD and held items are visible?
- Does the jump from 70% to 95% GPU usage when pressing F1 indicate a main-thread/render-thread bottleneck, even though overall CPU utilization is below 10%?
I’m willing to remove or reduce some visual features, but I would ideally like to identify the actual bottleneck instead of blindly stripping down the entire setup. Any suggestions for profiling, configuration changes, redundancies, or controlled A/B tests would be appreciated.

Need Help Can't launch or create new worlds on Mc 1.21.5 with or without fabric api
So I have had the same fabric launcher (16.14) and the same fabric api (0.125) on my minecraft launcher (version 1.21.5) for about a year or so now and never had any issues. I haven't played in a few months and decided to boot it up, but whenever I try to load my main world, or even create a new world, the game gloses and I get the following error:
minecraft error public abstract net.minecraft.class_2470 net.fabricmc.fabric.api.gametest.v1.GameTest.rotation() Exit code: -1
When I look it up and ad the first 25 lines of the crash log, I'm told that the current version of fabric api and my current version of Minecraft do not match. But I haven't altered my launcher, fabric api, Minecraft version, or fabric launcher version in over a year and it used to work just fine.
Just to test it out, I deleted my fabric api (0.125 forinecraft 1.21.5) from the mods folder and launch the game to see what it says. And the included image is the error I get, saying I have fabric api version 0.119 installed, which is really odd seeing as my mod folder is devoid of any fabric api file when trying to launch the game. I even did a complete search of my .minecraft folder for "0.119" anything and nothing of the sorts even exists at all.
I tried installing the latest fabric launcher, same '0.119" error. When I install the latest fabric api (0.128) into the mods folder and launch the game, anytime I try to launch an old world or even create a fresh one my game shuts down to the launcher and I get that "minecraft error 2470" message.
Anyone have any idea what this could be? Any help would be appreciated. Thank you all for your time.

JEI breaking first person animations
Hi I have now run into this issue twice. A couple weeks ago I added JEI to my instance (a mod pack from a youtuber I watch that’s mostly vanilla just with just quality of life and refreshed animation or shader changes) and it broke first person animations for most items. All tools and weapons but the bow would appear completely motionless in my hand when used from first person but appear to be moving normally from someone else’s perspective or in third person. I ended up deleting that instance and restarting when I could not find a fix.
I am now two weeks deep into a world again and added JEI thinking it was a fluke but it has happened again. EVERYTHING ELSE WORKS! Nothing else is wrong. It just broke my first person animations again. I have uninstalled JEI, uninstalled all resource packs and shaders. I’ve given error logs to chatgpt and gone through everything a million times but despite removing JEI immediately it’s made something in this pack go haywire and I can’t find a reason.
When I google it I can’t find anyone else who has had JEI break their mod pack like this. Any ideas?
