Heya all- hoping someone may be able to offer advice here. Sorry if I'm in the wrong section.
I am having huge performance issues running modded MC, and I mean that I typically average 7 fps. I cant believe that its my system... its not that terrible. Can anyone offer advice on how I can fix this? I'll start off saying I run the game on the lowest video settings with nothing in the background, on Windows 10 with updated Java version (x64) and optifine hd ultra.
My specs for my laptop are:
AMD A8-5545M APU w/ Radeon HD 1.70GHz, 8GB Ram, Windows 10 home - 64-bit
As I said, its modded, and I believe the main source of the lag is from IC2exp and/or Gregtech. which I am playing around with now. Didn't have AS severe problems running a nearly identical modpack replacing gregtech/ic2exp with TiC. I added java arguments as follows on reading up in forums, and it hasn't seemed to help in any major way:
Either way, i really think the 5-7 FPS i am seeing right now must be related to something I can resolve. Can anyone help, or direct me to someone who can? Thanks!
You have a quad core processor so why are you using -XX:ParallelGCThreads=10? All the graphs and benchmarks I've seen show better results setting this to the number of physical cores rather then logical threads. In either setting yours is 4 cores, 4 threads so you should being using -XX:ParallelGCThreads=4.
That's for the modpack that is running unplayably slow. Also, in case it is contributing to the problem, I have two different minecrafts that I use for the different packs- two folders I've called TIC.minecraft and the other is GregTech.minecraft. I have separate launcher profiles referencing the different folders. Thanks!
Honestly, I have no idea what ANY of the arguments mean! I just found a thread that listed them in one block and had a lot of comments with it helping people, and just stuffed them in there. I'll try the 4 threads first, then just try going with the default altogether. The issue I have is that I have relatively few problems running my other modpack, which is almost identical with the exception of Gregtech and IC2 being replaced with Thaumcraft and TiC. I experienced many slowdowns before I figured out I had 32bit java installed, and after replacing it with 64 bit I dont have too many problems. Although, even with the other modpack, I still average around 20 FPS. Its pretty sad, but playable. I feel like it shouldnt be THAT bad, given that I can run many recent-ish games without much problem.

As grimallq said, it is probably primarily because of the relatively slow CPU. However, try running it without Thermal Expansion and with FastCraft and see if that works any better.
I actually unchecked the jvm arguments and almost doubled my fps, so that was definitely part of the problem. I think I am going to put in an argument for 2gb ram usage. I just ran the gregtech pack and had much smoother performance, however serious glitches in the form of large empty chunks just refusing to correct. I'm hoping the additional ram argument will help on that. I'll also see how many processes/services I can clear from Windows 10 to save CPU,
I heard about fastcraft and grabbed it, but didnt put it in in case it was contributing. That could help? I heard it could be effective.
Thanks for all the advice, all! Anything else you think of would be greatly appreciated

Can we get a list of the mods you have installed?
Please don't PM me asking for help, I will just redirect you to the appropriate forum, where there are others who are far more skilled than me.
This is not the signature you are looking for.
Banners and such things

I'll give that a shot, thanks!
