[1.7.2]Optifog + Optimine

**z11** · 07-06-2011

This is a combination of both Optifog and Optimine in one complete package. Both Optifog and Optimine are FPS and performance boosters for Minecraft that have significant increases in performance when used both individually, and separately. One file includes both mods together* and the other two will be the mods themselves. They will be added in soon.

*The two individual versions are not compatible with each other, and if you want to use both mods you will need to download the combined version.

Optimine

This mod improves FPS, especially for slower computers. Gains of 20FPS and more are common. For people with slow computers, or lack a bit in specs and tend to lag a lot (or even a little) then those people should consider getting this.

What this is is the unofficial update of the Optimine mod originally made by Scaevolus. Scaevolus didnt update the mod after v1.3, so the community has taken it upon themselves to update it to work with the latest version of minecraft (Which is currently 1.7.2).

Features:
FastRender: More efficient chunk queue processing.
UniText: A completely rewritten text renderer. It's faster and supports Unicode, although the Unicode font files are not included with this release.
Fewer glClears: Erasing the entire screen is expensive. This mod avoids it when possible.
Better chunk drawing code: Removing a few useless transforms from the chunk rendering code lets all visible chunks be drawn in a straightforward manner.
Better Tesselation: Modified for speed. TNT explosions no longer cause clients to have horrible lag, and everything in general should feel faster.
Error handling: Don't go to a black screen when there's an OpenGL error. Print a decent error message to the command line instead.

Optifog
This mod is an FPS boosting mod, that alters the way fog is rendered in Minecraft. In vanilla MC, the fog is intrusive, ugly, and makes it hard to see anything while getting any amount of FPS boost out of it. This mod instead changes the way the fog is rendered, giving a much better look, while maintaining higher FPS even when playing on further render distances.

This mod is Modloader compatible.

General speedup 10-20%
Occlusion Culling without visual artifacts (Advanced OpenGL)
Mipmapping fixed, linear works without an alpha filter
Options moved to video settings screen (no more config file)
Fixed bug in PreloadedChunks
Added FAST OcclusionCulling (almost no artifacts visible)
Turned ON dynamic updates: when the player does not move loads 3 chunks per frame, when moving 1 chunk per frame.
Removed not needed classes, renamed back some fields. Should help with mod compatibility.
AdvancedOpenGL and FogType can only be turned on when supported by the hardware.
Now works with ModLoader
Now works with Optimine
Fixed lag spikes on sunrise/sunset and flickering blue blocks
Added Smooth FPS - fixes sporadic FPS spikes and stutter, stabilzes framerate
Added Brightness - lifts up shadow brightness, allows to see clearly at night
New "Limit Framerate" option: VSync

Features:

Pushes the fog away from the player so that it is only visible as transition on the render limits.
Uses a fast fog type on FAST and a better looking fog type on FANCY settings.
Decreases the render distance a little to get the same visible depth as before. On FAST decreases it even more to compensate for bad fog on screen edges.
Added experimental Occlussion Culling (hidden geometry removal) so only visible objects are rendered. Helps a lot on bigger render distances, on FAR and NORMAL doubles the FPS.
Added Optimine compatible versions (both "inio" and "303" versions of Optimine)
Added Texture mipmapping - far distances blend nicely, no more eyestrain.
Added chunk loading optimizations, like mod CAF. Configure how much chunks are to be loaded and how fast, define "loading free" walking distance, limit max number of loaded chunks, fast render distance switching without reloading chunks.
Modular and configurable. Install only the functions you need. Edit configuration file to turn on/off functions or change parameters. See "Readme.txt" and "optifog.txt" for details.

Compatibilities: READ THIS SECTION
For ModLoader: Install OptiFog AFTER ModLoader.
For MCPatcher (HD Textures): Install OptiFog without the "ji.class" (the mipmaps and fog distance will not be active). For HD fonts install without the "sj.class"
Compatible with: SinglePlayerCommands, TooManyItems, PlasticCraft, CJB's Modpack, Zan's Minimap. (Others as well, these are the major ones)
Not compatible with: GSLS Shaders, DynamicLights.

Proof:

Vanilla Minecraft 1.4_01, Settings: Fast

Optifog Settings: Fancy

Optifog Settings: Fast

All of these screenshots were taken on Normal render distance. FPS will improve the shorter your render distance.

See "Readme.txt" and "optifog.txt" for more details.

Configurable Options:

AdvancedOpenGL: Occlusion Culling, the game renders only the geometry which is really visible.
OFF: All geometry is rendered (slow)
Fast: Agressive, may produce minimal artifacts (but much less than the default Minecraft OC)
Fancy: Conservative, should have no artifacts
Fog: Select fog type if supported by the GPU
Fast: Faster, simpler fog
Fancy: Slower, better looking fog
FogStart: Select fog start distance
Min = 0.2: Close to player
Max = 0.8: Far from player, near to render limits
Mipmap Level: how many levels of mipmaps are to be used, decreases the flickering of distant objects, should not affect FPS
Min = 0: No mipmaps, Minecraft default look
Max = 4: Full mipmaps, some detail may disappear in distant objects
Mipmap Type: type of mipmaps, minimal FPS effect if any at all
Nearest: Faster
Linear: Better looking
Load Far: Enables fast render distance switching without reloading chunks, loads all the terrain at distance Far
PreloadedChunks: Enables movment in an area without loading new chunks
Min = 0: No preloading, after moving 5m new chunks will be loaded (default)
Max = 8: Preload 8 chunks, when moving up to 8 chunks (8 x 16m = 128m) no new chunks will be loaded
Bigger values force more chunks to be loaded at startup, which may take some time

Installation:
Navigate to your .minecraft folder (Instructions for that)
In .minecraft/bin Right click your minecraft.jar and open it with an archiver such as 7zip/Winrar
Drag all .class files from the file you downloaded in.
DELETE THE META-INF FOLDER
Close, and test.
