So my issue is that all of a sudden i started getting massive lag spikes. I've had RL Craft for about a week now and have put in maybe 25 hours so far and it has always run just fine with no lag whatsoever until today. i know its not my computer because it never did this before and my computer is pretty good. I don't know my actual specs but I've never had any problems running a game before. i can even run skyrim at full graphics with several mods and have no issues or lag at all and I've heard stories about how tough that game is to run so i dont know what is happening. i only have one world made and I've turned all the settings down as low as can be to make the game run as fast as possible but no luck. I'm posting because the lag started this morning and has progressively gotten worse. i gave the game a few hours to cool down thinking maybe it was just the long playing times but no luck. the lag is now so bad and happening so constantly that the game is now rendered completely unplayable. the lag happens only when I'm in a world and making a new one doesn't fix it. it happens even when i sit still and touch nothing or even in the menu when i pause. any ideas what i can do?
