I love how Microsoft has been put into its place as far as PC gaming goes. PC gaming was Microsoft's neglected platform, which rarely received any love. Microsoft basically had a monopoly on PC gaming because of DirectX and Windows, and they didn't see why they should improve their platform with no competition around.
As soon as Vulcan proved to be a viable option that pushed for openness and support of other operating systems such as Linux, we see Microsoft showing respect and throwing love at PC gamers. Better updates that prevent BSODs, making their exclusive games available not just on the Xbox platform but also on the PC platform, Xbox and Windows crossplay, and so forth.
This will also shake up Nvidia, and some of their shady business practices. Don't get me wrong all my cards have been Nvidia to this day, so I'm not being biased. Some of these shady practices include older cards dying from driver updates, which I've experienced first hand. My 580 was doing just fine until one of the updates hit, and my card died a few days after the update and many other people had experienced the same issue. The practice of overpricing their cards and releasing the Ti versions after consumers had spend so much money on the 80s should also be revised. I know AMD hasn't been perfect either, but I feel like these two companies can push each other through competition to better their products and support.
Competition is always good for the consumers, and I feel like Microsoft and Nvidia have competition now after a long time.
