About this modpack
This modpack is the most optimised way to run Distant Horizons with Iris shaders. This pack contains 62 performance and/or QOL mods and 6 DH-compatible shaders. I made this pack as I was tired of poor performance and inconsistencies when running Distant Horizons myself, so I compiled a pack of well-known and very useful mods and decided to share them to the world. I wanted the best possible performance while maintaining the stunning visuals that these mods can provide, and this pack is how I achieved it.
This pack is based off of Fabulously Optimized by robotkoer, however it also contains optimisation and QOL mods not found in this pack, and of course Distant Horizons and its requirements.
WILL ADD OTHER SHADERS ONCE UPDATED TO 1.21.1 ON MODRINTH (Photon etc)
