levitheman Posted February 12, 2014 Share Posted February 12, 2014 I haven't found any help with this so far, so here goes. System running: Windows 7 Home Premium Java 64-bit 16 gb ram (6 allocated to B-team) AMD FX-4100 CPU (Quad Core) Radeon 5500 graphics card Problem: Every 2-5 seconds I suffer a lag spike and a drop to anywhere between 1-13 FPS I have done the following: Allocated more than enough ram without changes Run on the lowest possible graphics, far runs the same as tiny. Reset the pack PLEASE HELP ME Link to comment Share on other sites More sharing options...
Ajthemodfreak Posted February 12, 2014 Share Posted February 12, 2014 You may have a 32 bit java install, check and see. Link to comment Share on other sites More sharing options...
MrMadMinecraft Posted February 12, 2014 Share Posted February 12, 2014 My friend had the same problem, he thought he had 64 bit java and checked on it, somehow it'd gone to 32 bit and essentially that was causing the jittery lag. Link to comment Share on other sites More sharing options...

Java is 64-bit Link to comment Share on other sites More sharing options...
Maxis010 Posted February 12, 2014 Share Posted February 12, 2014 (edited) More is not necessarily better with RAM, 2 to 3 Gb is the recommended, if you are still suffering lag at that then RAM is most likely not the issue Edited February 12, 2014 by Maxis010 Link to comment Share on other sites More sharing options...
Ajthemodfreak Posted February 12, 2014 Share Posted February 12, 2014 Well, if you've got 64bit installed and assign around 3gigs of ram to it and are still jittering the only thing I could think of is to try and install optifine but It's not really working right now with the pack, nei bugs and crashes.

levitheman Posted February 12, 2014 Author Share Posted February 12, 2014 I heard about some autosave setting that caused lots of problems, was that fixed? Link to comment Share on other sites More sharing options...

Ajthemodfreak Posted February 12, 2014 Share Posted February 12, 2014 Btw what is your fps? and are you doing anything in the background like rendering something or possibly have a lot of internet pages open especially youtube pages. Link to comment Share on other sites More sharing options...

I get 200+ in normal MC, and around 100 with most modpacks (I play upwards of 200 mods sometimes) Nothing else running Edited February 12, 2014 by levitheman Link to comment Share on other sites More sharing options...
matt8348 Posted February 12, 2014 Share Posted February 12, 2014 (edited) I'm having similar issues too but my computer is not as good as yours so I just assumed that was the reason for my issues. I get decent framerate (anywhere from 60-100) but every now and then there is like you said lag spikes. What is strange is that I did not have this problem when I was playing 1.5.2 version of the Tekkit pack but I did when I updated the pack to 1.6.4. So makes me think 1.6.4 version of minecraft causes some of these issues for some people. What seems to calm down these lag spikes is defragging my hard drive. Normal Windows defrag doesn't really help but I use a program called MyDefrag and it seems to work better. Again doesn't get rid of the lag spikes for me, but does reduce them a little bit.
