TECH REPORT'S just-published summary of Valve's Half-Life 2 presentation at an ATI function is nothing short of grim when it comes to the company's projections of how Half-Life 2 will perform on Nvidia DX9-class hardware. While a certain amount of Radeon-push / GeForce FX-bashing can be expected - this is, after all, an ATI-sponsored event - there are differences Globe Valves
to the marketing-speak that demonstrate just how serious the NV3X problems are. You'd normally expect lots of presentations filled with statements like: "ATI is a superior platform for our game", not graphs showing ATI hardware pulling no less then double the frame rate of Nvidia's best, to say nothing of slide after slide discussing the problem.
Then some enterprising MIT youngsters found a way to get Nvidia's very impressive "Dawn" demo running on ATI hardware (a supposedly "impossible" feat according to Nvidia) Reducing Valves
only to find that it actually ran faster under ATI's hardware than Nvidia's. Bring on the driver issues, optimization problems, 3DCenter's recent in-depth focus on NV3X hardware, and now this, and the tide of evidence is turning very much against Nvidia. Its not clear why the NV30 series has the problems that it does, but its clear that either FutureMark and Valve are in close cahoots to make Nvidia look bad, or there are serious architectural problems with NV30 and 35 that keep them from performing well. While some fanboys will no doubt jump for the former, an objective look at the data points more towards the latter.
What about Nvidia's claim that the FX benefits dramatically from optimized code? It might be true, but it won't save the situation. While GF FX 5900 Ultra performance did increase a fair amount from optimization, the 5200 and 5600 are still completely unplayable and barely benefited—though this may be because these two designs are, in fact, based upon the even-worse-performing 5800 Ultra design. This isn't really a solution either, since it took Valve 5 times as long to API Cast Steel Valves
code the Nvidia specific data as the general DX9 path. Valve's solution at the moment? Run the GF FX series as a DX8 part. Of course this means giving up all the DX9 eye-candy, but eye-candy isn't really useful when you can't play the damn game.

译文：暗示问题阀门正与Nvidia的DX9硬件可能会重新出现反复
作为第一个（当然最一对一等待）完全的DirectX 9游戏，半条命2将是一年中最大的成功，并将成为多年来作为一个技术演示和基准来。新的半条命2引擎，无疑会在其他游戏中，暗示问题阀门正与Nvidia的DX9硬件可能会重新出现反复，特别是如果他们不特别独有的半条命2引擎，而且我们倾向认为他们不是。
虽然是没有任何秘密事件如出一辙的表现并不那么强烈，NV35正在越来越多地漏的事情去了。首先，我们已经到3Dmark 2003的争议（如Nvidia公司的业绩不佳像素2.0首次曝光）。一个人真的归咎于在Futuremark部分坏了很多这一个基准，并考虑到3DMark '03实际上不是一个游戏引擎构建，这种批评了一些牙齿。
然后，麻省理工学院的一些进取青少年找到一个办法让Nvidia的令人印象深刻的“黎明”演示在ATI的硬件上运行（被认为是“不可能的”壮举据Nvidia公司），却发现它实际运行在ATI的硬件速度比Nvidia的。带来的驱动程序问题，优化问题，3DCenter最近在对NV3X硬件深入的重点，现在这一点，证据的潮流正在转向非常反对Nvidia的。它不明白为什么事件如出一辙系列的问题，确实如此，但它清楚，要么在Futuremark和阀门的密切勾结，使Nvidia的看起来很糟糕，或有严重的结构问题与事件如出一辙和35个不让他们表现良好。虽然一些fanboys无疑会跳前，一个客观的数据看点偏向后者更多。
究竟坏事情？非常糟糕。即使是Radeon 9600专业门诊步伐的绿外汇超过50％，而Radeon 9800的FX专业双打瘦弱的每秒30帧。这些指标都没有AA或自动启用。游戏甚至没有任何低于上播放的是FX 5900。
怎么样Nvidia的要求，极大地优化代码，从外汇交易的好处？这可能是真实的，但它不会挽救局势。虽然绿FX 5900超级性能并增加优化，5200相当数量和5600仍然无法播放，并几乎完全受益，虽然这可能是因为这两项设计，事实上，依据的，甚至更糟糕表现5800超设计。这是不是一个真正的解决方案，要么，因为它采取了阀5倍长的代码，作为一般的DX9路径Nvidia的具体数据。阀门的解决方案的时刻？运行绿FX系列作为DX8的一部分。当然，这意味着放弃所有的DX9眼睛糖果，但眼睛糖并不真正有用当你无法播放该死的游戏。
