speed mode

The tag 'speed mode' on WindowsForum.com refers to a performance setting found on certain laptops, particularly Sony Vaio models, that allows users to switch between integrated and dedicated graphics cards. In speed mode, the system uses a higher-performance GPU, such as an NVIDIA GeForce GT 640M LE, for tasks like gaming or graphics-intensive applications. Users may encounter issues where dxdiag does not display the dedicated video card even when speed mode is enabled, often requiring a restart after switching modes. Discussions cover troubleshooting this detection problem and understanding the difference between speed mode and stamina mode for optimizing system performance.
