在win10新系统中,用户操作的时候,偶尔会遇到一些奇怪而又陌生的词汇,其中directx12就是其中之一了,它是谁?directx 12是微软官方最新研发的游戏API,它将允许游戏开发者对特定的硬件进行优化,从而让游戏最大程度地利用PC硬件。下面,小编就来跟大家更加细诉directx12。
相信很多的电脑用户都有相似的经历,就是无论是Win10系统,还是一些大作游戏配置要求中,都可以看到有DirectX 12标注。究竟DirectX 12是什么,好奇的用户就问了,下面小编就来跟大家聊聊关于directx12了。
directx12下载
网上搜索“directx12”即可下载。

软件介绍:
据称,directx12可将游戏性能提高最多50%,另外新版本还有诸多改进和新特性,比如底层API、多线程、混合多显卡等,堪称革命性的版本,但可惜的是directx 12只会集成在新的Windows 10系统之中,目前并不支持Windows 7/8/8.1。

不过现在,国外某大神从Windows 10预览版中提取出了directx 12X运行时的安装包,经过试验完全可以在Windows 7/8/8.1上正常安装,而且如果显卡支持(NVIDIA开普勒、费米、麦克斯韦架构),系统会显示运行在DX12模式下。

特点介绍:
1、支持显卡
NVIDIA开普勒、费米、麦克斯韦架构,也即是GeForce 200系列及更高型号;AMD GCN架构,也就是Radeon HD 7000、Radeon R200/300系列;Intel Haswell(GT3)、Broadwell、Skylake核芯显卡。
当然啦,DX支持分为不同的特性级别,而能够完整支持DX12最高级别的目前只有NVIDIA GTX 900、AMD Fury系列。

2、新的特性
DX12最重要的变化就是更底层API,这一点很像AMD Mantle,在硬件抽象层上走得比以往更深入,能够同时减轻CPU、GPU的过载(overload)。
具体包括:应用可追踪GPU流水线、控制资源状态转换(比如从渲染目标到纹理)、控制资源重命名,更少的API和驱动跟踪,可预判属性,等等。
另外,DX12大大提高了多线程效率,可以充分发挥多线程硬件的潜力。DX11在这方面受CPU性能的严重制约,主要是因为不能有效利用多核心。
微软宣称,微软对多核心CPU的利用几乎是完美线性增长的,也就是说四核心能接近单核心的四倍。

此外还有渲染流水线、渲染特性、资源管理、命令列表与绑定、描述符跳跃等等方面的改进,因为主要是关于开发的,也比较深,这里就先不说太多了。
3、硬件支持
NVIDIA确认说,开普勒、费米、麦克斯韦架构全部都支持DX12,也就是GeForce 200系列以来的型号都可以,DX11的都行。
AMD则确认,GCN架构的所有显卡均支持Directx 12,也就是Radeon HD 7000、Radeon R200系列。
Intel确认称,第四代Haswell可以支持Directx 12,但其实仅限最高端的两个型号:GT3 Iris 5100、GT3e Iris Pro 5200。
目前还不知道它们是100% API支持还是仅仅特性集上的支持,但至少有一点,那就是DX12并不需要新的硬件才能实现,现有的就可以,因此它更像是DX11的一个扩展。

4、高通与移动
之所以把高通单独列出来,是因为这是它首次与微软DX联手合作,也是微软DX首次正式面向移动领域。
按照高通的说法,DX12可以大大提升能效,改进移动设备性能,而且在扩展性、移植性方面都非常好。

5、Xbox One
AMD刚才已经说了Directx 12会完全导向Xbox One,微软则表示,他们只花了四人月的精力,就把Xbox One的核心渲染引擎从DX11.1转向了DX12。
在此之前,已经有一些属于DX12的特性存在于Xbox One(看来谋划已久),其他的也已经移植过来。
关于directx12,小编就跟大家讲到这里了。
