About this project
What does FastBoot add?
⚡ FastBoot accelerates game loading by using mixins overwrites during early loading stage, particularly for heavy-modded setups ⚡
FastBoot operates on a simple idea: in most cases, data conversion and processing for every game version is unnecessary, so FastBoot delays them. As a result, the game loading speed decreases
🎮 Tests
⚡ FastBoot helps to boost the game loading speed by 1.5x-2x times, compared to tests without the mod ⚡
🎥 Here's a video showcasing the mod's tests:

| 1.17.x | 28 seconds | 10 seconds |

| 1.19.x | 16 seconds | 8 seconds |

🔧 Compatability
The mod works well with all other mods, including perfomance mods. FastBoot is fully compatable with OptiFine, Sodium, and other performance-friendly mods. However, because the mod does use some changes in game loading process: if you experience any compatibility problems, please leave a comment.
