Natal 占用 10-15% CPU 性能，移除处理芯片以节省成本

A few details about Project Natal's technical capabilities slipped out alongside the holiday 2010 release window at Microsoft's CES press conference. The most revealing of these specifics is that the hardware will only siphon 10 to 15 percent of the 360's CPU power, according to a statement from Natal lead developer Alex Kipman. "Natal has to work on the existing hardware without taking too much hardware processing away from the games developers," Kipman added.

However, according to a report obtained by GamesIndustry, the processing power could have been further reduced. The original build for Natal included a chip that processed the "bone system," assumed responsible for creating a skeleton of the player in front of the device's glossy eye. However, in an attempt to lower costs, the chip was removed from the device's final build, putting that processing onus on the software that will utilize Natal.

In other words, it's extremely unlikely that any software will be able to have Natal support patched into it -- a fact that Digital Foundry's Richard Leadbetter says could help "serve to focus developers on Natal-specific concepts as opposed to revisiting old classics."

Natal 计划开发主管 Alex Kipman 透露，Natal 将占用 Xbox 360 CPU 能力的 10-15%，他表示这不会对硬件处理能力有太大影响。

不过，GamesIndustry 得到的一个报告指出，CPU 处理能力会被占用更多。研发阶段的 Natal 有一块芯片负责处理骨架系统 (Bone System)，但是后来为了节省成本，最终版本中将这块芯片移除，改为通过软件方式处理。
