I hope that's another typo because Xmx shouldn't be passes as an argument into the FTBLauncher. Make sure you copied the right arguments. Also it would be 2048m.Hey there, I've tried using the FTB JVM Settings, but saddly, those corrupted my world. The game will not let me open anything. It's like im in "adventure" mode. I also, can not load any chunks, besides a few that we're loaded from my Chunk loader. But from that, it's fine, I'll start a new world.
The thing that is catching my eye is this:
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
This is with your settings, i've updated to the latest java 7u40.
I used the Vanilla launcher to see if these settings will improve. Hopefully, this helps. I'm not to sure what I am doing wrong I read this forum, and seen that you said that, 7u40 is fine, but "buggy"?
EDIT1: I've looked at my launcher, and it seems that, i'm getting this error:
Client> Invalid maximum heap size: -Xmx-2048m]
EDIT2: Fixed, it seems that I had a typo, -Xmx-248m derp. All fixed
ftbserver.jar is correct. Without quotes though.where it says " -jar “put your server jar name here” nogui" do you put ftbserver.jar or would it only be ftbserver?
Right, what JRE should I use, because I have 7u40, and when I loaded up my FTB world, my pips, liquiducts, etc etc. all were detached from each other, also, I could not load any chunks.SNIP
Well i use OP arguments and it works well on my bit old laptop. Before i use the one from your link and i had the same problem as you did. Terrible lags after 1 / 2 hours playing. But since i switch it out with OP arguments it seems getting better.I'm playing FTB Unleashed 1.1.4 on an older MacBook w/ MacOSX 10.6.8 [2 GHz Intel Core 2 Duo w/ 2GB 667 Mhz DDR2 SDRam] & Java SE 6 v1.6.0_51-b11-456.
Without additional java parameters, my system lags to the point of being frozen for over 10 minutes after 1 - 2 hours of gameplay. With the client side arguments listed here: http://binarymage.com/wiki/doku.php?id=setup:memory my game runs much better when I can get it to load but it also seems to be causing a ticking entity crash when loading (I have been able to get around this by starting a new world, then switching to my saved world).

Any specific recommendations for those of us playing on lesser computers?
I do not use ATLauncher nor the Technic launcher and have not tested anything with them so I do not support them. Not for any distaste for either, I just have no use for them. You can probably ask on their respective forums, but I will not be trouble shooting anything with their packs or launchers.
