What does 64-bit mean in terms of gaming?

In gaming, 64-bit refers to the architecture of a computer's processor that can handle data in 64-bit chunks, allowing for greater memory access and improved performance. This means a game can utilize more RAM (over 4 GB), resulting in better graphics, larger game worlds, and more complex simulations. Additionally, 64-bit systems can enhance multitasking capabilities, leading to smoother gameplay and improved overall efficiency in running modern games.
