⬇ Download on ModrinthWelcome to THE optimization mod for minecraft 1.21.1.
This minecraft mod is the culmination of my research and constant tweaking to make the most optimized version of minecraft you can play, while also improving the default visuals like the fog, clouds, water, particle effects, render distance, and so on.
Here's the frame rates that I normally get when sitting still, at 32 render distance.
Here's my specs if you want to know i7-7700HQ, GTX 1050TI, 24GB of ram, out of which I only use 4 for MC, and an HDD that I have at most seen running at 10MB/s. Note that this is just the beta. Expect a lot of changes, things added and removed between versions, crashes, and bugs at every step. I tried to minimize them to a minimum, but there's so much I can see on my own. So if you find anything, tell me, including criticisms.
