引用一下gzeasy大大的看法

这篇文章说的意思是:
“雷管FX在3DMARK03下会对某些场景没有变化的渲染对象比如天空这种背景保留计算值,然后在之后的渲染过程中直接“Reload”出来,这样就“省去”了对这些背静的处理时间/GPU运算/内存带宽。如果画面出现视点变换,驱动程序会重新进行渲染过程,把正确画面渲染出来,因此所有的截图都是完美无缺的,运行时渲染质量也没有受到影响。
可是当EXTREME TECH用开发者版本的3DMARK03变换测试者视角时,雷管FX并不知道测试者视角的改变,继续按照原来的程序保留某一角度下的背景计算值,因此会出现那些奇怪的画面。
EXTREME TECH的意思是:虽然不知道这样的“作弊”能够带来多少的性能提升,或许提升不大,但毕竟是“作弊”。
这样的手法的确很高明,没有任何画质下降同时提升性能。但如果这被证实是作弊,我认为NVIDIA有必要作出道歉,并在以后的驱动中修正问题。毕竟拥护需要的不是3DMARK03那些没有意义的数字,而是提升实际游戏性能。雷管FX本身在已经大幅提升实际游戏性能,这些并不是通过作弊得来的,即便没有3DMARK03,对用户来说还是一款实实在在的雷管。

倒底nv有沒有cheat,都還有待証實,原post的標題是頗為不妥
不過現在一片熱烈討論,也稱不上是什麼道聽塗說…

NVIDIA released the NVIDIA?DetonatorTM FX unified drivers for the Company's award-winning line of desktop, mobile, and workstation GPUs. The NVIDIA Detonator FX drivers deliver significant performance increases and improved image quality, and provide a robust suite of software applications designed to extend and enhance the visual computing experience. Detonator FX provides up to a 30% increase in 3D graphics performance in real-world gaming benchmarks, and works with the entire line of NVIDIA GPUs- from the brand new GeForceTM FX GPUs, all the way back to the five-year-old TNTTM GPUs.
43.45 44.03
875P + 3Ghz + FX 5800 1024x768 1280x1024 1600x1200
43.45 44.03 43.45 44.03 43.45 44.03
3DMark2003 (NoAA/NoAF) 4700 4872 3467 3611 2682 2792
UT2003 Flyby (NoAA/NoAF) 205.8 210.8 167.7 173.8 116.1 121
3DMark2003 (4xAA/8xAF) 2142 2359 1458 1595 957 1028
UT2003 Flyby (4xAA/8xAF) 97.6 110.7 67.1 75.8 41.8 45.8
Some bugs present in the 43.45 drivers are fixed and now the sky looks good on the 44.03 drivers. You can compare the image quality too of the 43.51 and Radeon 9800 Pro w/ Cat 3.2 here. The 3DMark2003 and UT2003 performance certainly improved with this new set of Detonator FX driver.
眼見為憑,不要道聽塗說. 原作者也太猛了吧,打個這麼聳動的標題..真是...
