If you have previously used MCPatcher for HD Textures, HD Fonts or Better Grass (important)
Follow these steps to prevent a possible "Black Screen" problem when installing OptiFine:
1. Temporarily revert back to the Default Texture Pack.
2. Uninstall the HD Textures, HD Fonts, and Better Grass mods from the MCPatcher. These functions are included in OptiFine.
3. Set Graphics to Fancy
4. Install OptiFine and test with the Default Texture Pack to make sure everything is working.
5. Select your previous texture pack and graphics settings
6. Run Minecraft and enjoy
Compatibility with other mods
When installing OptiFine together with other mods always make sure to install OptiFine last. The only exception are mods which are designed to be installed after OptiFine and say so in their install instructions.
If you need ModLoader: Install OptiFine AFTER ModLoader.
If you need Forge: Install OptiFine AFTER Forge.
MCPatcher is NOT needed for HD textures, HD fonts and BetterGrass, they are included in OptiFine. Install OptiFine without MCPatcher's HD features for best performance.
If you need DynamicLights (ModLoader edition): Install OptiFine AFTER DynamicLights.
I love fog! it's such a great concept!
And fog also has a horrific side which is awesome, and then you just made it even more awesome!
I'll sure be downloading this when it gets modloader compatible!
Great work keep going!
Private Mod Note
Rollback Post to RevisionRollBack
Censorship is telling a man he can't eat steak, just because a baby can't chew it.
Hmm, why does nothing help my FPS? Must be something wrong somewhere as all of these mods make no difference to my speed. I run between 18 and 25 no matter what mods or what settings I use, even putting a 64x64 texture pack on made no difference. It won't go smoother and it won't get worse. After a while of playing it lags but just cycling through the fog settings gets it back up and running.
As for this mod, I think I prefer the look of this fog over the inbuilt stuff, I think.
