I attempted to update the mods after updating Java to see if that would help with my severe FPS issues. Now, something is causing ores to generate on a new world again and I've troubleshot 30 different mods individually to see which one did it. Please, does anyone know which mod disables ores? I can keep that one as the original version.
Also, as I said I've been trying to play Regrowth but noticed severe FPS issues, whereas I'm able to play Monster with no issues. I don't know how a barren wasteland is giving me so many issues (my CPU goes to about 75% usage from this pack, too, most other packs don't exceed 15-30) haha. Any tips? I updated Java, video card drivers, and turned settings down. I lag to about 1-5 fps when I get an achievement and the stupid fireworks go off, too, anyone know how to turn that off?
Even though I don't have any real problems with java 8, I've heard many people saying that modded minecraft is not yet officially supported by java 8, so try the latest version of java.
Also, unless you're really experienced with modding minecraft yourself, DON'T update mods in a modpack with custom recipes and ore generation, it is very likely that one of the updated mods said 'oh this is a newer version and the config that already exists is for an older version, let me reload it to the default config', reverting to the previous version of the mod won't actually solve this problem, only redownloading the pack (or restoring a config backup) will remove that oregen again.
As for the FPS issues: try decreasing the render distance drastically (it does help) and actually putting a cap on the fps (like 30, it might look horrible, but instead of fluctuating between 1 and unlimited, it will stabilize at the amount you cap it too, if the cap is low enough, you might of course still get the occasional lag spike, but it's modded minecraft, don't expect miracles)
and for the fireworks, I believe someone mentioned which config it was in one of the previous pages, doing a Ctrl+f might do the trick
And I don't mean to be rude, but you are just using the standard minecraft texturepack right? Just saying that it would be an obvious answer for fps issues if you weren't, and you know, lot's of people like a bit of hi-res
Edit: and because I'm a nice bloke, this is the post in which the config was mentioned:
