ok im wondering if anyone else has this problem. let start off with my computer, i have 4GB of ram and i never lag on minecraft. back on 1.5.2 i could usually get 60-80 fps on single player all settings max. after the update that included the new launcher, there became a problem. i now have 5-15 fps on single player on render distance medium and fast graphics (never needed to use such low graphic settings in the past). that was too strange, so i did my research. other people had similar stories of 1.6 causing unnecessary lag. and im sure its not because i dont have optifine yet (optifine makers said that it is %50 complete for this update) and i was usually fine without optifine before also with around 40-50 fps
please tell me that you have similar problems do you know any ways to prevent this from happening.
its getting really annoying and i want it to go back to how it used to be.
