I am using a custom modpack with some of my favorite mods, and lately i've been getting some strange fps problems with my main survival world. It starts out at about 60 frames, like normal, then slowly drops down to about 7. This has no apparent cause, has only happened on that world (so far), and makes it nearly unplayable. It also has never happened before, it just seemed to start the other day. I did nothing that i think would affect performance when it started happening. These are the mods i am using:
Forge .953
CodeChicken core 0.9.0.9
NEI 1.6.1.9
Tinker's Construct (latest version for 1.6.4)
Ars Magica 2 1.1.2b
Backpack 1.27.34
Torojima's ChocoCraft 3.0.3
Morph 0.3.0
Flans 4.1.1 (with ye olde content pack)
iChun Hats 2.1.2
Iron Chest 5.4.1 build 702
MapWriter 2.0
These are all 1.6.4 mods, and this has never happened before. I did nothing that would likely cause this problem to start. I know that it might be impossible to tell without the world, but can someone give me some sort of advice as to how to fix it?
