We looked at the other modpack Mrjakedar Optimization and evaluated the mods to optimize it even more so your potato PC wouldn't lag. So this is the ultimate optimization modpack = Mr.Optimizer: Legend Edition
Many optimization mods have been removed because we looked into it and found that using too many would lower FPS and optimize performance. So we looked for the most compatible options, and this is the best.
This has been tested on my potato PC. Before, it ran at a maximum of 50-60 fps, but now with the modpack and our custom configuration, it runs at 170-280 fps on my potato PC.
These are just optimization mods. I promise you'll have a great gaming experience. I recommend you don't set unlimited FPS; it's better to limit it to avoid overloading your PC. I recommend limiting it to 100 FPS or 60 FPS IF YOU LIKE.
