My new latop has this problem in Minecraft when it freezes for like 1.5 seconds and it’s really starting to piss me off like fuck… AND it lags like hell when I leave it on the game menu for 5 seconds -.- This is balls and it really disappoints me.
It also runs out of memory every 15 mins.
le sigh This was the only reason I got a new computer so I could play minecraft without lag :C No.
Try using optifine if you arnt, the lag spike might be the auto save feature which optifine fixes, also try running it in fullscreen mode (F11 i think), that gets rid of a bit of lag too =]
I had a very similar problem Vaio. My PC is rocking, and I still had lots o trouble. The solution for me was a proper installation of Java. I needed the 64-bit version to fix whatever it was stopping it from working. Do you know if your OS is 32 or 64-bit?
Another option is to update video drivers. Oh, and try installing Java from internet explorer instead of firefox like I did. Did any of that help?
Unfortunately I can’t really suggest anymore than they have. Though driver updates do generally help, if you haven’t done that already. Also do Windows updates as well.
