Fast as Fabric

Fast, efficient, and optimized Fabric modpack built for minimum lag and maximum performance

This modpack serves as a base for other modpacks, or as a simple solution for maximum performance in vanilla Minecraft. It was inspired by optifine_alternatives and fabulously-optimized with a focus of validating claims through benchmarks and removing unnecessary mods.

Benchmarking

Raw results are available in the benchmarks directory. The following setting were used:

• fullscreen
• 4GB RAM allocated
• max FoV (Quake Pro)
• vsync off
• max framerate unlimited
• render distance 8
• peaceful
• creative
• all other settings are set to lowest unless specified.

A world is created using seed 2151901553968352745 and baseline settings are configured. After 2 minutes a baseline image created and cloned for each benchmark. All benchmarks are performed 2 minutes after loading into the world.

Benchmarking was done using the following tools:

• MultiMC
• Carpet
• Fabric Chunk Pregenerator

Testing methodology and data presentation inspired by:

• Phoronix
• Gamers Nexus
• Krausest Web UI Framework Benchmark
• TechEmpower Web Framework Benchmark

Hardware

• Intel i7 6700
• Nvidia GTX 1060 3GB
• 16GB DDR4 (4GB allocated)

Glossary

rdp

• relative delta percentage
• measurement / baseline - 1 * 100%

fps

• average frames per second
• measurement of understanding visual smoothness

tps

• average ticks per second
• measurement of server smoothness and responsiveness
• /tick warp 10000

cgps

• average chunks generated per second
• measurement of server and world generation smoothness while exploring
• pause game after starting pregen (escape menu) to stop server ticks from consuming CPU time
• manually timed
• =10000/(time)
• /pregen start 50

ram

• memory usage in MB
• singleplayer reflects client + server usage

rdp sum

• sum of relative deltas as a percentage
• used to determine overall impact of the mod

Notes

• Sodium entity culling is disabled as it's done more aggressively by the EntityCulling mod

Additional settings to improve server performance:

• in game /gamerule disableElytraMovementCheck true
• in server.properties allow-flight=true
• in server.properties use-native-transport=true use only on Linux servers
• in server.properties view-distance=8 less than 8 can affect mob despawn behavior
