FTB Unleashed L.S.O.D.

[Ithambar]

Hey fellow FTB players,

I am not sure, if this is the right place for it, but I have been trying to fix this the whole day and am kinda tired.

I am experiencing the socalled Lag Spikes of Death (L.S.O.D.) when playing any of my Unleashed worlds. It only happens with Unleashed, not with Vanilly MC nor any other FTB modpack.
I tried about anything suggested on the internet from Optifone up to a virtual partition on my RAM, but nothing worked.

Does anybody have any single clue what I could be doing?


I really want to play FTB again...

The only thing I can see in this, is that everytime Minecraft autosaves, this lag appears.

But I do not know, how to deal witth this. I was able to play Unleashed without any problems before.

1. It's not autosaving:

Saving and pausing game...

It's autosaving when you press ESC.
2. Have you tried going to Optifine > and setting FPS Limit to Vsync (drag that slider to the left) and using Fast Advanced OpenGL?
Another thing: what are your system specs? Even if Unleashed worked without lag for some time, your specs could still help .
Something I also recommend is to regularly defragment your Hard Drive. Read this Microsoft article on how to do it.

 

[Ithambar]

Hmm, no, changing those settings did not work...

Anyway, here are my specs:

Windows 7 Home Premium Edition (64-bit) Service Pack 1 (Build 7601)
8087 MB RAM
Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz
Intel(R) HD Graphics 3000 | NVIDIA GeForce GT 650M


At least I hope these are all the important values...

And yes, I should defrag my Hard Drive, didn´t do that for some time...

Try removing Optifine and make sure your Java 64 is update 40. Those 2 things are what fixed it for me.

Intel(R) HD Graphics 3000 | NVIDIA GeForce GT 650M

Well, since you got both Intel integrated graphics and Nvidia discrete graphics, that could explain the whole problem.
Nvidia uses the Nvidia Optimus Technology to change between your Nvidia graphics card and the Intel graphics card. It doesn't detect Minecraft as a program that needs a powerful GPU.
In other words, DirectX games that don't use Java (pretty much any other game: Battlefield. Batman: Arkham City. The Elder Scrolls. Pretty much anything) will use the powerful Nvidia GPU. Minecraft, on the other hand, it's not deemed as a demanding game.
Tl;Dr; Go to the Nvidia Control Panel. Then click on the drop-down and select "High Performance Nvidia Graphics"

Many, many thanks. I actually managed to get FTB to run again. I am so happy you all tried your best to help me.

Thanks!

 

[Gerald Huppertz]

Can you tell us what you did to fix in case others have similar issues.

Thanks

 

[Ithambar]

Well, I tried everything suggested here, and in the end Guild Master´s last post did it. I told my pc to use the high graphic drivers in general and espacially for all Minecraft related stuff.
