That's all well and good on paper, but Optifine in a lot of cases has become as much of a necessity as a Mod Loader itself.The people can wait. It's beta. Therefore, incomplete. A work in-progress. When it's done, then look for versions of mods that aren't included. That is when you'll find ones that should work. And if they don't, chances are, user error.
I really don't think people will remain patient about it for long. Not for this.[DOUBLEPOST=1353468654][/DOUBLEPOST]
Have you tried making a multiplayer enabled modification to Minecraft with over 10 different mods without directly touching the minecraft.jar file?Yes, please explain why you think OptiFine needs to be specially configured for FTB for it to work. When, 1) it works just fine for many people, improving FPS as it should, and 2) there's nothing special that FTB adds to the process other than an easy method to install mods, all of which work perfectly well with OptiFine, and have since it added built-in Forge compatibility months and months ago.
If the OP is having an issue, and there are people here willing to help him with the issue, why does it matter if it isn't not in the pack? I understand why Slowpoke and the pack authors don't have an obligation to support users in this case, and that's fine. But coming in here and insisting that the user is as fault because he's using a mod not in the pack is flat out wrong, and I believe contradicts the spirit in which this project came together.
Try it, you might be surprised just how much configuration is needed.
