同时也谈到了下一代的DirectX 10... 都是英文的= =
Here's a list of several new Direct3D 10 performance improvements
GameSpot was able to wrestle out of the DirectX 10 team:
New constant buffers maximize efficiency of sending shader constant data
(light positions, material information, etc.) to the GPU by eliminating redundancy
and massively reducing the number of calls to the runtime and driver.
New state objects significantly reduce the amount of API calls and bandwidth,
tracking, mapping, and validation overhead needed in the runtime and driver to
change GPU device state.
Texture arrays enable the GPU to swap materials on-the-fly without having to
swap those textures from the CPU.
Resource views enable super-fast binding of resources to the pipeline by
informing the system early-on about its intended use. This also vastly reduces
the cost of hazard-tracking and validation.
Predicated rendering allows draw calls to be automatically deactivated based
on the results of previous rendering - without any CPU interaction. This
enables rapid occlusion culling to avoid rendering objects that aren’t
visible.
Shader Model 4.0 provides a more robust instruction set with capabilities like
integer and bitwise instructions, enabling more work to be transferred to the
GPU.
The D3D runtime itself has been completely refactored to maximize
performance and configurability by the application.
跟DX9 最大的不同 我想就是 CPU 跟GPU 被完整的区隔了..变成两个独立的单元~
而且GPU 处理的所需储存的资料也不再受显示卡上记忆体大小的限制,而是可以
直接存取系统的实体记忆体罗~这真是一大福音阿! (文章我没贴上来,请自行到下面的
网址观看...)
GPU受CPU 的干扰也越来
越少~可以专心的处理影像资讯 文中也提到了SM 4.0...
7系列支援的SM3.0 已经能让目前的游戏表现的淋漓尽致...
真的不敢想像SM4.0 所带来的震撼影像!!
请大家拭目以待吧~应该是今年的下半年会发表吧?????
