Memory leak in1.7.10

[pirahnah3]

Hello all, not quite sure if this is the spot for this but it did not have a specific area otherwise. Please move if needed. 

 

I am having ap roblem playing any 1.7.10 modded minecraft pack, not just here at Technic but also from FTB and AT launchers as well. 

 

Packs I have tried:

the 1.7.10 modpack 

Modsauce

FTB Alpha

Direwolf

 

All produce the same issue and that is a constant memory use. In game I can watch the memory % used constantly run at 17% and go up to 40% and then back down. The longer i play the higher it goes until ultimately the game starts to freeze or becomes unplayable due to low FPS. I have tried with and without optifine and the same results occour. I have tried Superflats, amplified, BoP, and standard. 

 

Comp Specs 

Mac Pro 4.1

2.66 quad core xenon 

640gb 5400 RPM drive 

20gig ddr3 ram 

Radeon Sapphire HD 7950 graphics card 

Java 7u72 

 

This is NOT an issue for any 1.6.4 modpack i have tried, Attack of the B Team, Agrarian Skies, FTB, Tekkit, or Hexxit (Did not do alot of gameplay on hexxit or tekkit). 

 

Help is appreciated thank you.

Weird. you have any specific settings in your Technic Launcher/FTB Lanuhcer?

[pirahnah3]

nothing specific in the launchers I know of, I keep the ram at 4gb or less. I have tried at 2, 3, 3.5, and 4 and this occurs at all levels tested.

• Does this happen with Vanilla?
• Are your video card drivers up to date? Have you tried beta drivers?
• Does the memory usage growth seem to be independent of which 1.7.10 modpack you are using?

[pirahnah3]

have not tried vanilla, only have tested on modded. 

Vid card brand new install drivers checked upon install and were up to date (install less than 2 weeks ago)

no it does not.

You tried Fastcraft? 1.7.10 is almost unplayable without it....

 

Edit: It's this or you're running out of memory and the OS is starting to swap big-time.

I have tried Fastcraft and Optifine, the leak happens both ways. 

 

Running out of memory is onyl the issue after a time of playing. The machine has over 20gig however i have been advised to not allocate more than 4gig to the launchers.
