Well guys Ive been having some odd happenings regarding my PC and minecraft recently, I didnt make any changes to minecraft recently no new mods or anything but Ive recently started to experience some lag, now normally I would just do something to fix this such as lower my render distance for a little but thats not helping and some other problems are accompanying it. They include: My Pc running louder then usual when minecraft is open and my memory usage in minecraft has been starting with high numbers (upon entering my world it is already hovering in the 60% and quickly goes up) now Im not sure how the memory usage part works but i know I usually have a lower number and it usually goes down a bit if not alot by closing and re-opening minecraft. Something I noticed also is my allocated memory is at 100%, it may have always been like that but i did happen to notice it. Is there anything I can do to lower the memory usage and get rid of the lag?

Ive also noticed I only have 494mb of allocated memory, I feel like that number used to/should be higher, if so, how can i fix that?

Try using this to lower RAM usage if you don't use a heavy texture pack
java -Xmx512M -Xms512M -jar "Minecraft.exe"
*Make sure the launcher is on the same directory like this code
*Make this a .txt file and then save as a .bat file (clear the .txt extension and put .bat instead)

Im using Faithful 32x32,but it lags no matter what pack I use, what do you mean by "Make sure the launcher is on the same directory like this code"?
