Computer gamers spend a lot of time playing.

I bought a new computer and just started playing. It has 4 cores.

Does your operating system and the game itself support simultaneous operation of multiple processor cores? Because, for your information, a quad-core processor will work well on a single core, and if not, it will be no faster, or even slower, than a good dual-core processor. If it is faster, it will only be marginally so.
