Severe Lag(Mac)

[diamondeye83]

Last week, my tekkit would run, (minimum smooth lighting, fast graphics, normal render distance) at about 45 FPS witha maximized window. I havent played this week because ive been busy, but now when i play on the default window size i get 20 fps, same settings as above, and on maximized window, i get no more than 5 fps. Anyone know what might be causing this?

EDIT: tried tekkit lite, classic, and hack/mine, and they had the same issue. Might be a launcher problem then

Hi yeah this problem has just hit me too i cant work out for love nor money what the problem is. I have every thing even lower then normal now and its just crazy low fps.

Yeah I suspect the Launcher Updates to the /bin files (jinput.jar, lwjgl_util.jar, lwjgl.jar, natives, and minecraft.jar) are to blame. Really not happy that this fix was rolled out to provide Java 7 support, WHICH WE NEVER NEEDED. Technic Devs, if you are listening, PLEASE rollback your changes so Mac users aren't hit by this issue. I'd rather have a stable, playable system than support for a framework we don't yet need. When Minecraft hits 1.6, we apparently might have to have Java 7 support, but until then we are happy to play on Java 6.

Same problem here. It's very annoying! The FPS is 40 and yet the game still lags like crazy! This is unbearable! OSX 10.8.4
