Microsoft Corporate Vice President Marc Whitten has talked out about some of the changes that Microsoft is making to the final developmental kits of the Xbox One. These changes include a new graphics driver and increased GPU clock speed.
On a recent podcast with Major Nelson, Whitten stated, "This is the time, and this is the thing I think people are going to see as we get into Gamescom and people get their first look at new things since E3. This is the time where the developers have the final Dev Kits in their hands, they're really working closely with us on how things have come together. There's some things that have really started to come together quite well." Whitten also stated, "Since E3, an example is that we've dropped in what we internally call our mono driver. It's our graphics driver that really is 100 percent optimised for the Xbox One hardware. You start with the base [DirectX] driver, and then you take out all parts that don't look like Xbox One and you add in everything that really optimises that experience. Almost all of our content partners have really picked it up now, and I think it's made a really nice improvement." For those wanting to know the original clock speed was 800 MHz and it has been bumped up to 853 MHz, it isn't a major improvement but it is an improvement nonetheless.
I personally am looking forward to this upgrade to the Xbox One. It is just another promising feature that Microsoft has added to the next-gen Xbox. Although I won't be able to afford the Xbox One, I do believe that increased GPU clock speeds and a new graphics driver are great reasons to buy the Xbox One.
