Indium VS Starlight

I did find this on the issue tracker (https://github.com/comp500/Indium/issues/207) Which version of Fabric API are you using? 0.84.0 or newer is required.

Iris Shaders + Sodium - Link - Indium - Link - (Indium is needed for many other Sodium based FPS increasing mods) - Increases performance and shaders performance

Fabric has its own optimization mods. For performance, there is a great Sodium mod. To optimize the Lithium game world. To optimize Phosphor light. These are the main Minecraft optimization mods for Fabric. For shaders there is an Iris mod. Also, if you're playing with Fabric mods, don't forget the Indium rendering mod.

Indium (Required for Sodium compatibility)

You'll need CIT Resewn (and possibly Indium, but I'm not 100% sure). After this, you can follow any tutorial on how to make such resourcepack for OptiFine or MCPatcher, as CIT Resewn supports both.

indium github.com/comp500/Indium and continuity www.curseforge.com/minecraft/mc-mods/continuity allow you to have connected textures with sodium and lithium

If you don't also want Forge mods, they list the combination of Continuity and CIT Resewn as alternatives. (While not directly related to this usecase, if you go that route I would recommend also installing Sodium, Indium, Lithium, and Starlight.)

Indium to make Sodium compatible with some of the following mods.

Since they were Linux computers, then I assume they play Minecraft Java, which means there's a lot of ways to optimize the game to make it run a lot faster, sometimes even 3 times faster. This tutorial fully explains how to download Fabric mods, and this modpack is the best way to optimize Minecraft. The modpack might be a little complicated to download but it's absolutely worth. I downloaded just 2 mods (Sodium and Indium) on a computer that turns into a slideshow when Chrome is opened but they made Minecraft playable. The modpack also allows for shaders that make Minecraft look much better, almost like AAA games with RTX on.

Well Starlight seems to be out already. And it works better than Phosphor and supports 1.17 Fabric

https://github.com/Tuinity/Starlight makes chunks load way faster though, works for me

Go here and find column "Releases"(on right), and click on "tags", under description of latest version you can find word "Assets". Click on it. Download only file with "starlight" in name, and last bat not leatest -> put into mods folder. Fabric loader is required.

If you don't want to use the patch, or you are facing this issue but are not using paper(or playing singleplayer), you can use starlight (and ask your friends to do so too) on the client side. The jar file can be found in the Releases tab (only available for fabric atm).

Here is what I have found is the best for FPS boosting and general optimizations in 1.17:𝗜𝗡𝗗𝗘𝗫❎ = not compatable w/ other mods (does not apply cross catagory)🔼 = better of the incompatable ones📖 = requires an API to work[#] = footnoteAll mods here are for the fabric loader (https://fabricmc.net/use/)All mods here are for 1.17.x-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉𝗙𝗣𝗦 𝗕𝗢𝗢𝗦𝗧𝗜𝗡𝗚❎🔼Sodium https://modrinth.com/mod/sodium-Sodium Extra https://modrinth.com/mod/sodium-extra-Indium https://modrinth.com/mod/indium❎[1]Enhanced Block Entities https://modrinth.com/mod/ebeCull Leaves https://modrinth.com/mod/cull-leavesEntity Culling https://www.curseforge.com/minecraft/mc-mods/entitycullingBetter Beds https://modrinth.com/mod/better-beds📖[2]Tweakeroo https://www.curseforge.com/minecraft/mc-mods/tweakeroo𝗥𝗔𝗠 𝗥𝗘𝗗𝗨𝗖𝗧𝗜𝗢𝗡Hydrogen https://modrinth.com/mod/hydrogenFerriteCore https://modrinth.com/mod/ferrite-core𝗪𝗢𝗥𝗟𝗗 𝗚𝗘𝗡/𝗟𝗢𝗔𝗗 𝗜𝗠𝗣𝗥𝗢𝗩𝗠𝗘𝗡𝗧Lithium https://modrinth.com/mod/lithium𝗟𝗜𝗚𝗛𝗧𝗜𝗡𝗚 𝗜𝗠𝗣𝗥𝗢𝗩𝗠𝗘𝗡𝗧Starlight https://github.com/Tuinity/Starlight/releases𝗕𝗢𝗢𝗧𝗜𝗡𝗚 𝗜𝗠𝗣𝗥𝗢𝗩𝗠𝗘𝗡𝗧❎🔼LazyDFU https://modrinth.com/mod/lazydfu❎DashLoader https://modrinth.com/mod/dashloader𝗡𝗘𝗧𝗪𝗢𝗥𝗞𝗜𝗡𝗚Krypton https://modrinth.com/mod/krypton𝗧𝗣𝗦 𝗜𝗠𝗣𝗥𝗢𝗩𝗠𝗘𝗡𝗧📖Fast Furnace https://www.curseforge.com/minecraft/mc-mods/fast-furnace-for-fabric𝗔𝗣𝗜MaLiLib https://www.curseforge.com/minecraft/mc-mods/malilibFabric API https://modrinth.com/mod/fabric-api-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉-҉𝗙𝗢𝗢𝗧𝗡𝗢𝗧𝗘[1] Enhanced block entities is not compatable with Sodium unless Indium is also installed and a special version of sodium which can be found here: https://github.com/CaffeineMC/sodium-fabric/actions follow instructions below to get correct version.Step 1: Go to https://github.com/CaffeineMC/sodium-fabric/actionsStep 2: Click on the latest workflowStep 3: Click on the text labled "build-artifacts"Step 4: Open zip that was downloadedStep 5: Take out file that ends in ".jar" and only ".jar"Step 6: Put the .jar file into your "mods" folder and if Sodium is in there remove it[2] Tweakeroo with the settings (disableBlockBreakingParticles, disableDeadMobRendering, disableParticles) in TweakNo Toggles set to true

Use Iris Shaders, Starlight, and Lithium (other two are on curseforge, they are all mods but don't need Fabric API)

Delete phosphor from mods, and download and paste this

Go here https://github.com/Tuinity/Starlight/releases download the appropriate release for your Minecraft version and place it in your mods folder. For best results use sodium, lithium and hydrogen with it.

Starlight: Complete rewrite of the lighting engine. It also works better than Phosphor
