A setting is only changed if it is already in your options.txt. Values in the table show the target; the file keeps its own format.
How to use it
- Open your .minecraft folder and find options.txt.
- Drop it on the box above (nothing is uploaded).
- Pick a preset. Potato PC gives the most FPS; Balanced suits most computers.
- Download the boosted file, close Minecraft, and replace your old options.txt with it.
- Start the game. Not happy? Put the backup back.
How it works
options.txt is a plain list of settings like renderDistance:12. The booster changes only the heavy settings that already exist in your file, and writes each value in the exact format your file uses, so it works on old and new Minecraft versions. Everything else, like your keys and sounds, stays exactly as it was.
Questions
What gives the biggest FPS boost in Minecraft?
Render distance has the largest effect, followed by graphics mode, particles, clouds and smooth lighting. The Potato PC preset lowers all of them.
Can this break my game?
No. It only changes values that are already in your file, keeps every other line, and gives you a backup. If you don't like the result, put your old options.txt back.
Should I also install performance mods?
On Java with Fabric, performance mods such as Sodium, Lithium and FerriteCore can raise FPS a lot more. Use them together with these settings.
Does it work on Bedrock?
No. Bedrock stores settings differently. This tool is for Minecraft: Java Edition.
