Just similar to optifine, grouping particles together and giving the option to turn them on/off

e.g. potion particles,
animated textures (lava, water, nether portal)
along with the amount of particles shown (built into mc) : All, Decreased, Minimal
(rest in attached screenshot)

optional: option to enable/disable block breaking particles as seen in the brilliant mod: Patcher by Sk1er

(Maybe some bug fixes found in Patcher could be used in some of your other mods)

Do you have data to show that particles are a significant source of lag w/ Sodium? We already optimize particle rendering quite a bit.

Not at PC right now, but I can confirm that with alot of modpacks played with optifine, the particle switch is a significant factor as to why my fps is above 300 in some cases (80-120 frames without).

Will test this and provide screenshots tomorrow as I am in England.

You Can install Sodium Extra For These Features Simple :)

This Option You Cannot Find In Sodium Extra But You Can Try To Find A Mod For Fabric Which Is Supported With Sodium

ok thank you!
