Abstract: Methods, servers, and systems for enhancing the performance of gaming applications through cloud computing. The method comprises receiving user information, which includes object states or visual effect data related to a game, from at least one user. Based on the specific game channel in which the user is playing, the method determines whether the user information requires processing by cloud computing. If cloud computing is required, the user information is transmitted to a computing server. The computing server processes the user information to generate graphics-related results, which are then transmitted back to the user's device for rendering, optimizing the gaming experience by leveraging cloud resources while minimizing the computational load on the user's device.
