usefulmods VS PolyMC

I wouldn't install optifine, the majority of mods don't play well with it. Opt for Rubidium, Sodium, or another combo with the mods listed here: Modlist Link

highly reccomend using rubidium/magnesium if you're on forge, they are faster and have less incompatibility issues, here's a list of mods that work well for performance enhancing https://github.com/NordicGamerFE/usefulmods

does laptop have a GPU? if yes, is it being used? in-game F3 screen to check. top right about 4th or 5th line down. if no, optimizers may help a little. a good list

I would suggest that you try out any performance-enhancing mods, after a bit of research to see if they have any known conflicts with anything you already have (this is a good list). Be careful (back up first!), and be prepared to back out any changes.

No, not really. No one was in charge at the beginning. It was a community project with multiple people having the administrative role at the same time. LennyMcLennington was one of the contributers, but not really an important one. But he removed the administrative rights from the actually important people. Devs like flowln and Scrumplex played a much bigger role. Even after half a year being the only developer at the PolyMC-Project Lenny still heasn't caught up with what other conributers had done in a few months before. See: https://github.com/PolyMC/PolyMC/graphs/contributors

Could I suggest trying a different launcher such as PolyMC? You can get this on deck in Linux linkand sign into your microsoft account to access Java. This version also has the benefit of you being able to get modpacks.

It's still open source, the repo hasn't moved. https://github.com/PolyMC/PolyMC/

The issue is: the main developer freaked out, made a post ranting about political bs, kicked everyone from the GitHub project and now it's been 2 months since it hasn't been updated. The developers who used to contribute to "PolyMC" moved from the "PolyMC" project to the "PrismLauncher" one after the drama.

There was no prompting or provocation towards lenny at all. The code of conduct existed for ages before lenny deleted it on oct 17 2022: https://github.com/PolyMC/PolyMC/commits/358f080c76dbdfc65f32e08448a5e38b78d2bab0/CODE_OF_CONDUCT.md

First, it's gio that handles trash in SteamOS. Second, after digging into PolyMC's code, it also leverages trash. Was added roughly 7 months ago in this commit: https://github.com/PolyMC/PolyMC/commit/02f30de1c11fa53e61c199032a3280afe618e3b2
