I have been getting really low fps. I have allocated 8GB of ram to the game, and it didn't help at all. Here are my specs: Processor Type Intel Core i7-4700MQ Processor Cores 4 Processor Speed 2.4 GHz Processor Cache 6 MB L3 Hard Drive Speed (Revolutions Per Minute) 5400 rpm RAM Size 16 GB RAM Type DDR3 RAM Speed 1600 MHz RAM Slots 2 (0 Available) Optical Drive Dual Layer SuperMulti DVD+/-R Graphics Chipset NVIDIA GeForce GT 740M with Optimus Video Memory Configuration Dedicated Dedicated Video Memory Size 2 GB OS Windows 8
I Would love if you could help me!
First off, never allocate that much RAM to Minecraft, it straight up doesn't need it. Also, one thing I have noticed about 1.7 is that it has some memory leakage. Go to edit profile in the launcher and in JVM Arguments type these:
The first one limits Minecraft to a max of 600MB (An unmodded client should never have to go above that) but tell it to dynamically allocate only what it needs, and the second one tells Java to speed up garbage collection on the game, which will greatly reduce wasted memory. Using both of these, I was able to go from 30-40 FPS in 1.7 to 70-80. I can't say for sure if it will work quite as well for you, but it is worth a shot.

The problem with the truth, is that it never lies.
