If you have a bad computer you need to make the graphics lower, if it still doesn't work you need a better computer. Business computers don't work well (Use home premium or professional). More space on your computer can help. You should not use too many texture packs or high-quality texture packs (like LB photo realism). Having Mods is fine (just don't use too many).
Lag, viruses and not the proper game. And if you love the game so much why not support mojang (creators of minecraft) and buy it?
Your computer is old.
there is no viruses on minecraft just lag and pixelmon has none to
Yes, but it might lag.
That depends on your computer.
There is none. Lag is produced from your own computer, not recording systems.
Forge, Forge is very popular and runs several Big mods like Tekkit and The House mod. Forge is completly lag free.
The answer is right on the minecraft.net site genius. It is an out of date classic version of minecraft, lag-o-saurus as I would say. Get minecraft, it isnt that expensive, unless your REALLY poor to the point where you probably stole the computer your using to ask this.
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.
use a 64-bit java to run minecraft. Or install optifine to reduce lag
To get Minecraft for free, you need to download it on Xbox.
Minecraft requires java my mom said it is no suitable when I played it (for free) it keeps showing the menu later.. it starts lag
