That attitude has slowly been changing, and now Nvidia is announcing their first notebook driver release. Going forward, the company will be providing CUDA-enabled drivers for mobile GPUs, giving any GeForce user an easy way to stay up to date. Part of this change, Nvidia says, is due to the change in their driver architecture, with a switch to a modular design and an unified installation package. The drivers should work on any notebook with an Nvidia GPU and not cause any alterations to vendor-specific functionality, such as notebook hotkeys.
AMD has been working for some time to release drivers for Mobile Radeons as well. As both companies continue to expand upon this, hopefully nobody will have to rely on notebook vendors to provide drivers anymore, and finally keeping up with the desktop world.
