Minecraft Forums

So my system Specs are:

Cpu: i7-6700k 4.00GHz

Gpu: gtx 980

Ram: 16gb DDr4 in dual channel

Drive: 224Gb Kingston HyperX Savage SSD

So my system should be more than capable of handling anything minecraft can dish out, but I seem to crash every time I die. Then the game runs at around 2 -> 0.5fps for quite a while after reloading. From my interpretation of the dump it seem to have a major memory leak! What can I do to solve this issue and make minecraft playable again?

Thank you
