Absolute Realism

Transforms Minecraft into a realistic game, with vast and beautiful world,
cinematic graphics, lots of new content, and completely overhauled gameplay.

Important

Allocate 4-8GB RAM to play!

Turn off VSync for better performance in Options -> Video Settings -> General.
By default LOD Dropoff Distance is set to extreme, which noticebly impacts performance but gives the best graphics possible. This can also cause severe lags in specific conditions on weaker hardware. You can fix that by setting LOD Dropoff Distance to High in Options -> Distant Horizons (the cube on the top left in options) -> Advanced options -> Graphics -> Quality.
If you want to play with guns you have to turn on FAR_BLUR_ONLY in Video Settings -> Shader Packs -> Shader Pack Settings -> Post Processing -> Depth Of Field settings.
If you experience a visual bug "melting GPU" fix that by re-enabling Rendering in Distant Horizons options.
If you want to generate chunks faster (real chunks, not DH) consider increasing Chunk Update Threads in Options -> Video Settings -> Performance.
To see info about new items - use REI mod, the search bar to the right of your inventory. You can use @ to see items from a specific mod.
