That depends on your computer.
Your computer is old.
There is none. Lag is produced from your own computer, not recording systems.
Currently HD texture packs are not supported my Minecraft, and therefore are bound to lag. Having a powerful computer may prevent lag from occurring due to an HD pack, but not always. To fix lag due to HD packs try making sure the only program you are running on your computer is Minecraft as HD textures tend to make Minecraft require a lot more RAM.
Because your xbox can't handle the lag.
A slow/low end broadband speed is usually the #1 problem for lag on servers. The other is too little ram on the computer on single player, 4 gigs should be the minimum you should have. If you go to the minecraft WiKi they can tell you how to add more ram to the Minecraft application if you have plenty on the computer. Things that you can do to reduce the lag is to turn down some of the visual options in the menu.
No air probably has outdated hardware to run it with a huge lag
you can always go for a alienware computer as they are designed for gaming
yeah. anything with over 2 gb of ram or you'll get loads of lag
Minecraft uses Java, which is slower than what other games use.
If it where possible i would say yes, it could be if you have a super fast computer.
You may need to download the newest version of Java for minecraft to work. Or maybe your computer can not handle it.
there is no viruses on minecraft just lag and pixelmon has none to
