The Atom Modpack is an experimental modpack, featuring the most effective mods in terms of optimizing Minecraft. The pack itself is not ready and expects bugs or crashes.
Use
The Atom Modpack provides a highly optimized version of Minecraft, which aims to provide the best possible performance, and maybe break the game itself and strip it from some components:
reworked light engine;
a new and optimized rendering engine (Vulkan);
general optimizations, regarding culling and loading times.
Statistics
By my own tests, using my own hardware, I was able to achieve a more-than 730 FPS boost! It really might be dependent on the actual resources of every system, but the Vulkan rendering system is compatible with almost every modern desktop PC.
P. S. : All of the mods added are stated in the "dependencies" tab of every version of the modpack, if some are interested into looking at their respective use.
