=====================================================================================

WHAT MAKES IT DIFFERENT FROM OTHER PACKS ?

There are lots of modpack out there for 1.12.2 but most of them dont include a mod called 'Nothirium'. You can read more about it on its official curseforge page. This mod along with all other mods will improve you fps upto 2x-5x depending on you PC.

FPS TEST

I tested it on my old laptop. Here are the specs:-

CPU-- i7-5500U

GPU-- Integrated graphics 5500

RAM-- 6gb (4gb dedicated to minecraft)

I was able to achieve 150-170 fps on a newly generated world at 1600x900 resolution (slightly below 1080p) with optimized settings

INCOMPATIBILITIES

A few mods are incompatible due to nothirium's optimization which includes-

Full Incompatibilities

FarPlane2

LittleTiles

Albedo

Colored Lux

Partial Incompatibilities

Optifine: Make sure that 'Smart Animations' is disabled in the graphics settings. Also custom block render layers from Optifine won't work with Nothirium.
