Description

BetterFps is a Minecraft mod that add a few performance improvements, trying to be compatible with other mods.

If you have two screenshots comparing with and without, PM me.

These screenshots are outdated and many improvements have been implemented since then.

Improvements

All improvements can be enable or disabled in the config file (config/betterfps.json) or in the options menu (Options -> BetterFps Options) (For older versions, press F12 while in game).

Algorithm

Changes sin() and cos() algorithm. There are 7 algorithms. Each one of them may or may not help you, it really depends on the hardware of your computer.
Currently, it's pretty similar from what FpsPlus used to do, but it doesn't edit base classes.

I have plans to expand this, not in more algorithms, but in algorithm generation based on benchmarks.

Affects both client-side and server-side.

Memory Preallocation

Removes a RAM preallocation of 10MB. This allocation was added to prevent players from starting the game with low memory, but this allocation is kept until its almost the memory reaching its limit. This was made just for players using modpacks, where memory might be a problem. If you have enough memory, this is pretty much useless for you.

Only affects client-side.

Fog

Removes the fog. The fog creates a lot of lag, why not add an option to remove it?

Only affects client-side.

Beacon Beam

Removes the transparent layer of the beam. It might help it when there's a lot of beacons.

Experimental - I'm still testing if it actually helps anyone, I might remove it.

Only affects client-side.

Fast Hopper

Hoppers are very unoptimized, they keep checking for items to pickup when there's no need for it. Simply putting a solid full block on top of it stops looking for items to pickup.
Recently, Forge has added the new capability API, which forced me to remove others improvements. I might reimplement them in the future.

Only affects server-side.

Fast Beacon

Beacons are also unoptimized, the code processes stuff that it didn't need to. Not only it was recoded thinking in performance, the code was also organized for processing stuff only when it needs to.

Affects both client-side and server-side.

Fast Search

The creative mode search is really unoptimized, in big modpacks, the pressing any key in the text input would freeze the game by a few moments. This improvement implements a smart search algorithm, reusing old results for new searches. It will also prevent any non-alphadecimal key (such as shift) from updating the search.

It also supports multithreaded/asynchronous searches: they will prevent lag spikes from happening when searching

Only affects client-side.

Installation

Installation for Minecraft Forge

Find the game installation folder
Drop the mod file in the mods folder

Note: The mod will not appear in the mod list due to a missing feature in Forge. I've been trying to add this feature to Forge for about as long as this mod exists, but this is up to Forge devs, not me :/

If you want to check if the mod is installed, you can open the options menu, it should have a BetterFps button in there.

Installation for Minecraft Vanilla

Double click the mod file to open the installer
Click "Install"
Change the installation directory, version and profile according to your preferences.
Open/Restart the Minecraft Launcher
Play the game :)
