Yeah when you load the Items over and over and over again. But what about that there is a static list which never changes unless you force it to (rejoin world/restart game/Command)
then it would not really lag the game and you can create lists for easier access. So you do not have to loop through everything 1000k Times.
And since these recipes are not required on server side (since the recipe showing is only client sided) there should not be that much lag at all. But i personally Prefer nei no longer. I saw that it is getting stuck every now and then,
also it is not crashproof with broken recipes. I mean i can normal craft stuff and when i search in nei something it crashes (it was a broken recipe on my side) but craftingguide had no problem with that. Just throwed a error message for peoples bugreport and thats it.
I think this:
Also you should install NEI, I don't care if you like CraftGuide more, or if NEI crashes far too often for you and everyone else, because Chickenbones sadly still doesn't know how to do a simple try/catch, CraftGuide just doesn't cut it and it will probably never do so. And the Wikis? Seriously, you consider just using the Wikis instead of NEI? Do you really think the Wiki Editors can keep up with this Mod? I add Recipes faster than they can edit the Pages. The Wikis are only really useful for How-To Guides and Machine explanation.
I have the same thought of gregorius.
However, you could put a config to disable / enable the display of recipes, like "hideSecretRecipes" does ?
Maybe "hideReplicatorRecipes" ?
