This modpack won't add anything new to your world, but it will significantly improve the performance and smoothness of the game. The modpack contains shaders. The modpack optimizes many aspects of the game, for example, if you do not look at the mobs, they do not load, thereby increasing performance (a creeper can still grow up from behind and blow you up)

Also included in the assembly is the blur+ mod, which adds blur when opening settings or inventory.

And added mods to improve visualization and game effects. Added texture packs for small shields, swords and fire (they need to be enabled in the settings).

The assembly optimizes chunk rendering and eliminates the loss of RAM memory.

All tests were carried out using 20 chunks of rendering (all other settings at maximum). GTX 1660 super graphics card and Intel core i7 2600 processor
