• Minecraft Version: 1.12.2
• BetterFps Version: 1.4.8
• Forge/LiteLoader Version (if any): 1.12.2-SNAPSHOT
• Other Mods (if any): OptiFine and CSL but I can tell that they did nothing.

When I try to use both BetterFPS and liteloader as libraries I found that it crashes with no crash-report, I think that's because the game doesn't start at all...I mean, the log part hasn't been loaded yet.
If I delete BetterFPS's tweak or LiteLoader's tweak, then it starts but the mod whose tweak I delete won't get loaded.
And BetterFPS can't be loaded by LiteLoader. I don't want to install a forge. I tried to use forge before and it works well, but Forge eats too much memory.
How to solve it?
