Hi there.I get incredible lag spikes on survival games servers.I don't get it because in singleplayer or on other servers i get no lag, even with highest graphics with optifine.When i join, it's ok for like 1st 3-5 minutes but then my FPS drops to 2 and it becomes literally unplayble.I tried everything from updating java,reinstalling MC,using optifine (all versions), also tried allocating more memory for java and MC but i still get lag.Can anybody help me?
