Hey, I've made a video tutorial of installing OptiFine with Forge ModLoader for Minecraft 1.6.2:

[youtube][/youtube]

I have MCA, Fossil & archeology mod, TMI, Forge, and a pig buddy mod. I use Magic launcher to organize and add my mods. I recently downloaded optifine, the light version, and my game takes 10+ minutes for it to load... Is there anything I can do to fix this?

Have you tried changing the loading order of Optifine? Putting it in different places?

You could try loading ONLY Optifine and not the other mods to see if it is just Optifine or a potential conflict with a specific mod.

I said it once, I'll say it again: I'm having huge lag spikes when I use HD B4. Is anyone else having this problem?

Can the mod developer make an OptiFine update for Forge 804?

my minecraft freezes when i use optifine

good mod I will give diamonds!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11 :Flint and Steel: :Flint and Steel: :-( ): :-( ): :Dia

while everything is slow for mojang you should, do some stuf in the todo list

Quick heads up if your going install this and Chicken Bones' mod's.

If you install optifine and CB's mods. It will most likely cause a crash. But i'm sure CB is looking into his mods and getting them updated.

Just wanted to let you all know.

Love this mod and I've been using since it since 1.2. I've always been able to install it without any problems. But now I'm trying to install it on 1.6.2 with Forge and every single time, the game fails to start and I get this error message in the dev console:

(I'm on OS X, BTW)

I've followed the instructions perfectly. I've tried installing Optifine multiple times now and every time it fails. If anyone has an idea what I'm doing wrong, I'd be grateful.

They work fine together, make sure to have at least Forge 804, it won't work with Forge 789...

For some reason I can't get this to work when I use MagicLauncher.

private float getCharWidthFloat(char par1)
..
if (var4 > 7)
{
var4 = 15;
var3 = 0;
}

Or sorry i mean that part of code...
if (var4 > 7)
dont allow normal char weight ... for non English fonts

First, don't people use spoilers anymore?
Second, I don't really see a problem. Just get close to the chunks and they'll render. However, if you see a black pit, able to see the blocks in the sides of the surrounding chunks, reload your world. Or, get away from the holes, then reload the world.

Quote from LukeDuhMeh

Optifine is totally broken on OS X.
After the manual, correct install, this error pops up:

I've been having the same exact problem. (OS X, nearly identical error message)

Is anyone NOT having problems with 1.6.2 and OptiFine? I know people post bugs here, but usually there's a relatively even distribution of "thanks!" posts. Since 1.6 it's all negative, and I'm holding off upgrading from 1.5 because of it. If 1.6 is this bad, and OptiFine is not compatible, then I will sit it out until 1.7.

So, seriously... anyone find that it worked just fine??

Works just fine for me. Nine out of 10 times the reviews you'll find online are negative, because when people are happy with something they generally don't feel a need to give feedback, but give them trouble and they will complain to no end.

As long as I don't want Forge (I don't) it's working fine for me.
Using Magic Launcher to select the Forge environment, and then using Optifine (Ultra B4) stops Minecraft from loading up.

But if I use Magic Launcher with the Vanilla 1.6.2 environment, adding the Forge src zip file, any Modloader mods, and then Optifine, everything is just peachy.

I'm yet to try in the Forge environment with an Optifine other than Ultra B4, but that is because I don't actually use any Forge mods - just modloader ones.
