So I just noticed last week that my used memory keeps going up, then down usually causing lag spikes, from 200+ fps down to 0 or 100, something that's noticable. (It'll go from 30% to 50% used memory then crash to 30% etc at all %'s) Sound is also glitchy, goes on then off every second when it rains. I tried with all my mods, vanilla, different versions, no texture packs, and on my laptop as well. I have no idea what is causing this, but it's very inconvenient that it keeps crashing on me. I tired google, and didn't come across much, or what I did didn't help me. Any help would be appreciated. Thanks
