    我们接下来将要考察 EVGA GeForce GTX 275 CO-OP PhysX Edition和XFX Radeon HD 5850 Black Edition这两款显卡的性能,下面是我们使用的测试平台信息。

    CPU:Core i7-975 Extreme Edition processor (3.33 GHz, 6.4 GT/s QPI);

    散热器:Scythe SCKTN-3000 Katana 3 ;

    主板:Gigabyte GA-EX58-Extreme mainboard ;

    内存:Corsair XMS3-12800C9 (3 x 2 GB, 1333 MHz, 9-9-9-24, 2T);

    SSD硬盘:Samsung Spinpoint F1 HDD (1 TB, 32 MB buffer, SATA II);

    电源:Ultra X4 850 W Modular power supply;

    显示器:Dell 3007WFP monitor (30", 2560x1600 @ 60 Hz max);

    操作系统:Microsoft Windows 7 Ultimate 64-bit;

    显卡驱动:Nvidia GeForce 196.21 WHQL for Nvidia GeForce;

    ATI Catalyst 10.1 for ATI Radeon HD.

    AMD显卡驱动设置如下:

    Smoothvision HD: Anti-Aliasing: Use application settings/Box Filter

    Catalyst A.I.: Standard

    Mipmap Detail Level: High Quality

    Wait for vertical refresh: Always Off

    AAMode: Quality

    Other settings: default

    NVIDIA驱动设置:

    Texture filtering – Quality: High quality

    Texture filtering – Trilinear optimization: Off

    Texture filtering – Anisotropic sample optimization: Off

    Threaded optimization: Auto

    Vertical sync: Force off

    Antialiasing - Gamma correction: On

    Antialiasing - Transparency: Multisampling

    Multi-GPU performance mode: NVIDIA recommended

    Multi-display mixed-GPU acceleration: Multiple display performance mode

    Set PhysX GPU acceleration: Enabled

    Ambient Occlusion: Off

    Other settings: default

    测试所使用游戏一览:

    第一人称射击游戏:

    Call of Duty: Modern Warfare 2

    Crysis Warhead

    Cryostasis

    Dark Void

    Darkest of Days

    Far Cry 2

    Left 4 Dead 2

    S.T.A.L.K.E.R.: Call of Pripyat

    Wolfenstein

    第三人称射击游戏:

    Batman: Arkham Asylum

    Resident Evil 5

    Street Fighter IV

    RPG类游戏:

    Fallout 3: Mothership Zeta

    模拟类游戏:

    Colin McRae: Dirt 2

    Tom Clancy's H.A.W.X.

    即时战略类游戏:

    BattleForge

    World in Conflict: Soviet Assault

    目前市面上有很多PhysX加速方案,除了EVGA GeForce GTX 275 CO-OP PhysX和XFX Radeon HD 5850 Black Edition 的对比测试以外,我们还加入了下面几种情况。

    GeForce GTX 275 + GeForce GT 220

    GeForce GTX 275 (PhysX acceleration enabled)

    GeForce GTX 275 (PhysX acceleration disabled)

    AMD的HD5800与HD5900性能比NVIDIA同级别显卡强,硬件规格也高出不少,唯独在PhysX加速上被NV狠狠玩了一把,不过这并不代表没有办法破解这一驱动程序上的限制。本次我们测试使用XFX Radeon HD 5850 Black Edition+驱动破解之后的Geforce GT220作为PhysX加速卡的组合来与EVGA GeForce GTX 275 CO-OP PhysX Edition进行对比,看一看哪种方案更好。
