Capes VS fabulously-optimized

Sadly no. BUT there is a client side mod called capes which let's players have custom capes but you have to have the mod to see other players custom capes

After a quick search I found this mod called Fabric Capes, which might be what they're talking about

Fabric Capes (by VictorKohler)

You can install Kappa or Fabric Capes alongside sodium/iris for optifine capes

You can replace all of Optifine's features with the right Fabric mods, like Continuity, CEM, Animatica, FabricCapes, and Iris. I don't know all the features Optifine has, but every important feature Optifine has that I can think of has a Fabric mod counterpart.

Well, there is the Fabric Capes mod, it shows capes from OptiFine and a whole bunch of other mods

you can get to see your capes in fabric, just add this mod https://www.curseforge.com/minecraft/mc-mods/capes :)

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.
