very high lag/chugging

[Mystipony]

Hey, new here, not sure where to put this, sorry if it's in the wrong place.

But when I play minecraft my game gradually slows down and starts lagging and chugging really bad, it's much worse with the technic pack, and I'm not sure what to do. I heard that allocatting more memory to my minecraft might help, but I'm not sure I can do that with the Technic Luancher.

Here are my specs,

Processor: AMD Phenom 8450 Tripple-Core Processor 2.10 GHz

Memory (RAM): 4.00 GB

Graphics Card: NVIDIA GeForce 6150SE nForce 430

System type 64bit operating system

Yes, I know I need a new graphics card, and more RAM, but that's shouldn't be the problem I wouldn't think, Minecraft isn't that graphic intensive, more RAM couldn't hurt though.

Just because minecraft not be a top of the range triple A blockbuster HD shooter, doesnt mean it isnt graphics intensive. Mooooor graphics card=Mooor FPS. In some cases, LESS ram can be better. Try half a gig.

So, noob question here, but How do I change how much RAM I have allocated to Technic?

I know how to do it in normal minecraft, but I don't know how to with the Technic Launcher and all that.

Actually I think 1GB is the recommended (and default) RAM alloc for Technic; iirc it was something like >2GB and Java starts getting screwy.

How long is it before things start to slow down? Does it run fine for half an hour and then start getting bad? Is it slow from the start?

[freakachu]

the ram settings are in the options menu in the launcher.

It's about 3-5 minutes in and then it happens. I have found a 'temporary solution' it goes back to being fine for another 3-5 minutes if I change the smooth lighting slider, even a little. but it's rather inconvienient to do that ever 3-5 minutes.
