I was sick of all the optimisation Modpacks I found including non-optimisation-based, intrusive mods, so I took it into my own hands and created a modpack that improves and optimises the game without adding any intrusive features
Optimisations include:
- All compatible sodium mods
- Iris
- client-side Noteblocks to remove lag when listening to Noteblock music (especially useful on large servers)
- Bad optimisations to optimise non-visual related features
- Chunky for better chunk management
- Entity culling
- Fast quit
- Dynamic FPS so AFKing won't eat your resources
- Noisium for better terrain gen
- Server ping fix
- No texture pack reload screen
- Optimised player rendering (especially useful on large servers)
- Render distance beyond that of the server
- Asynchronous pack scan for faster texture management
- and much, much more
