As stated in the title, my minecraft is really laggy until the moment I let minecraft load by itself ( without typing on my keyboard/clicking anything with my mouse), It will not respond after opening mc for 4 secs and just crashed... I have incrased the java heap size to ''-Xms2G -Xmx2G'' already and my mc still lags badly. I am receiving only 50 fps with optifine in minecraft 1.5.2. However, in minecraft 1.6.1, im receiving about 18 fps without optifine as my minecraft just simply off by itself upon installing the mod. I am using windows vista with duo-core processor only. Is there any other solutions...other than purchasing a better graphics card? The lag is really KILLING me .
Also, some quick solutions:
- Get Optifine
- Run with smooth lighting off
- Normal viewing distance
- Particles minimal.
My video below also shows some tips to fixing lag:
