Final answer:
A game might use more CPU instead of GPU due to low graphics settings, a stronger CPU in relation to GPU, game optimization, or outdated graphics drivers.
Step-by-step explanation:
When a game is using more CPU instead of GPU, it could be due to various reasons. Games are designed to distribute tasks between CPU and GPU based on the nature of these tasks. The CPU handles game logic, physics calculations, and input/output operations, while the GPU is primarily responsible for rendering graphics. However, if the game's graphics settings are set to low or if the CPU is stronger relative to the GPU in your computer, the CPU may be handling a more significant part of the workload. Additionally, the game engine itself or the game's optimization could favor CPU usage. It's also important to ensure that your graphics drivers are up-to-date, so your system correctly utilizes the GPU for gaming.
