INFO
This modpack is made to boost your fps, so you can use it to boost your fps. The only mod that doesn't contribute to more fps or is dependency is iris shaders. This pack is client side, but some of its mods will work on the server side as well. Use this if you want better performance in minecraft. It also contains a shader and a nice texture pack. You can use this as a base for your modpack. More mc versions will be added in the future.
PERFORMANCE
This modpack boosts the performance by a ton. In a big storage room, my fps without any mods was 200-300(with default settings and 16 chunks). With the modpack it increased by ~640%, going to around 1700-1950 fps. Because I have a decent pc, I can use shaders, and with shaders my pc gets around 120-180 fps with 12 chunks and 80-110 with 16 chunks(with complementary unbound ultra preset).
Without the modpack here I get 314 fps:
With the modpack here I get 2277 fps(624% fps increase):
