Existing dx10 graphics cards do not support dx10.1

Switch from "driver home"

At Siggraph 2007, a world-class computer graphics image event held in San Diego, California last week, Microsoft officially confirmed that Windows Vista SP1 will upgrade DirectX to 10.1.

When introducing the features of dx10.1, there is a saying that "Supported on upcoming Hardware". We can understand it as "the latest hardware supports ", it can also be understood as "only the latest hardware will be supported ". Recently, INQ reported that Microsoft interpreted this sentence as the latter. This means that if the fever gamer buys geforce 8800 or radeon HD 2900 at a high price and has not run several dx10 games yet, it is theoretically outdated.

Of course, this does not have much impact on normal players. dx10.1 has not added any new features to improve the image quality, nor has it made any improvements to the development environment. Basically, dx10.1 is to redefine some of the features originally set as optional in dx10 as mandatory features, such as upgrading 16-bit floating point texture filtering to 32-bit, 4x msaa multi-sample anti-sawtooth and so on. These new features require both Vista SP1 and new graphics cards and game software, so players do not need to worry too much at present.

Despite this, this forced upgrading of users is still unpleasant, but we should blame Microsoft for its fast upgrade and the poor foresight of graphics card manufacturers, or is it too slow for the game vendor dx10 to launch?
