Minecraft-Region-Fixer VS fabulously-optimized

Your best bet is to either entirely delete the chunk or use an application like this

- [Mon 18:37:52 ERROR Minecraft] [Multiverse-Core] The world 'spawnv2' could NOT be loaded because it contains errors and is probably corrupt! - [Mon 18:37:52 ERROR Minecraft] [Multiverse-Core] Try using Minecraft Region Fixer to repair your world! 'spawnv2' - [Mon 18:37:52 ERROR Minecraft] [Multiverse-Core] https://github.com/Fenixin/Minecraft-Region-Fixer - [Mon 18:37:52 ERROR Minecraft] [Multiverse-Core] Failed to Create/Load the world 'spawnv2'

If you have other backups of the world without corrupted chunks in those locations, I would recommend using this tool: https://github.com/Fenixin/Minecraft-Region-Fixer

try https://github.com/Fenixin/Minecraft-Region-Fixer

I'm unable to exactly trace down when did these errors start showing up because I only recently figured to use DiscordSRV to log the console, however, we first saw these issues after a player traveled so far and so fast from spawn that the server ended up running out of memory while that player was alone online (we have 4GB of RAM and the player went to 40+ thousands with an elytra or a boat). Since that caused the world to jump in size, I downloaded a copy of it and ran this region scanning script: https://github.com/Fenixin/Minecraft-Region-Fixer to rule out chunk corruption or something similar, and the script didn't find anything wrong.

Since you mention having backups, you can try using MCEdit to replace the bad chunk or use MC Region Fixer.

Try running this on your world and deleting any corrupt chunks https://github.com/Fenixin/Minecraft-Region-Fixer. Make a backup first obviously.

That said, there was a forum thread where they would fix corrupted worlds, though it is no longer actively monitored and I don't know of any general "corrupted save recovery" place; otherwise, there is a tool, Minecraft Region Fixer, which will fix corrupted chunks (updated through 1.18; not sure if it will work on 1.19 but I don't think it made any changes to the save format), but may not be able to fix every issue (e.g. issues with specific blocks or entities). Note that in either case there may be data loss when resetting corrupted chunks/deleting entities/etc (best case is that no player builds were affected).

There are some features that optifine has that sodium doesn’t, but there are tons of mods that add them. You can find a list here, but Fabulously Optimized is a well-known and popular modpack that adds sodium, other performance mods, missing optifine features, and much more. You can also use Prism Launcher (a fork of MultiMC) for an automatic install of Fabulously Optimized with auto updates, and to be able to manage your mod packs and launch them with single clicks instead of having to manually change your mods. Alternatively, if you won’t use shaders or resource packs, Simply Optimized is essentially a “lite version of fabulously optimized without all the QOL mods like connected textures or the shaders mod (I’d recommend adding zoomify for the optifine zoom). Let me know if you have questions

Have you tried this https://github.com/Fabulously-Optimized/fabulously-optimized

There's a really cool modpack called Fabulously Optimized that should boost your FPS considerably. See https://github.com/Fabulously-Optimized/fabulously-optimized/

Right right. I only mentioned that because it was the only one listed with the word grass in here https://github.com/Fabulously-Optimized/fabulously-optimized/blob/main/INCLUDED-MODS.md

OptiFine isn't liked by the modding community nowadays, being closed-source, kinda slow and doesn't run on Fabric. I'd suggest Fabulously Optimised, the modpack, over OptiFine.

Have a look at the Fabulously Optimized Modpack. It is a Vanilla+ (Fabric) modpack optimized for maximum performance and has a bunch of QoL mods. Check the compatibility of these and whether these fit in your modpack. I do this everytime I start playing a new modpack.

you can try getting some of the mods under the smooth section in this list: https://github.com/Fabulously-Optimized/fabulously-optimized/blob/main/INCLUDED-MODS.md but other than that i can recommend assigning a key to turn shaders off when near large create contraptions which is what i usually do. you see shaders + large create contraptions dont work well unless you have a 4090 or something so sadly there is no way of fixing it. you can also try other shaders that are more optimized like this one: https://www.curseforge.com/minecraft/customization/chocapic13-shaders

See https://github.com/Fabulously-Optimized/fabulously-optimized...

If you feel comfortable using CurseForge's launcher to manage modpacks, this is a quick and easy option for the maximum performance you'll ever get out of Minecraft. It is currently at 1.19.2, but the github lists all the mods included which may have 1.19.3-compatible versions. You can also see the changes to the configs.
