最强硬件最新驱动最悍游戏最牛系统A/N大比试！ - POPPUR爱换

We are going to investigate the performance of new ATI and Nvidia graphics card drivers in contemporary gaming titles running under Windows 7 using the following testbed:

Intel Core i7-965 Extreme Edition processor (3.2 GHz, 6.4 GT/s QPI); Gigabyte GA-EX58-Extreme mainboard (Intel X58 Express chipset); Corsair XMS3-12800C9 (3 x 2 GB, 1333 MHz, 9-9-9-24, 2T); Maxtor MaXLine III 7B250S0 HDD (250 GB, Serial ATA-150, 16 MB buffer); Enermax Galaxy DXX EGX1000EWL 1000 W power supply; Dell 3007WFP monitor (30", 2560x1600 @ 60 Hz max display resolution); Microsoft Windows Vista Ultimate SP2 64-bit; Microsoft Windows 7 Ultimate RC1; ATI Catalyst 9.7 for ATI Radeon HD;
Nvidia GeForce 190.38 WHQL for Nvidia GeForce.
The graphics card drivers were configured in the following way:
ATI Catalyst:

Smoothvision HD: Anti-Aliasing: Use application settings/Box Filter Catalyst A.I.: Standard Mipmap Detail Level: High Quality Wait for vertical refresh: Always Off Enable Adaptive Anti-Aliasing: On/Quality
Other settings: default
Nvidia GeForce:

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

We selected the highest possible level of detail in each game using standard tools provided by the game itself from the gaming menu. The games configuration files weren’t modified in any way, because the ordinary user doesn’t have to know how to do it. We made a few exceptions for selected games if that was necessary. We are going to specifically dwell on each exception like that later on in our article. Unfortunately, we couldn’t complete our performance tests in Call of Duty: World at War because the game version e had at our disposal worked incorrectly under Windows 7 and wouldn’t let us launch a single-user scenario.
We took one single-processor and one dual-processor graphics solution from each camp. Here are the graphics cards that will participate in our today’s test session:

ATI Radeon HD 4870 X2 (2 x RV770, 750/750/3600 MHz, 1600 sp, 80 tmu, 32 rbe, 2 x 256-bit, 2 x 1024 MB GDDR5) ATI Radeon HD 4890 (RV790, 850/850/3900 MHz, 800 sp, 40 tmu, 16 rbe, 256-bit, 1024 MB GDDR5) Nvidia GeForce GTX 295 (2 x G200b, 576/1242/1998 MHz, 480 sp, 160 tmu, 56 rbe, 2x448-bit, 2 x 896 MB GDDR3)
Nvidia GeForce GTX 275 (G200b, 633/1404/2328 MHz, 240 sp, 80 tmu, 28 rbe, 448-bit, 896 MB GDDR3)
We ran our tests in the following resolutions: 1280x1024, 1680x1050, 1920x1200 and 2560x1600. Everywhere, where it was possible we added MSAA 4x antialiasing to the standard anisotropic filtering 16x. We enabled antialiasing from the game’s menu. If this was not possible, we forced them using the appropriate driver settings of ATI Catalyst and Nvidia GeForce drivers.
Performance was measured with the games’ own tools and the original demos were recorded if possible. We measured not only the average speed, but also the minimum speed of the cards where possible. Otherwise, the performance was measured manually with Fraps utility version 2.9.8. In the latter case we ran the test three times and took the average of the three for the performance charts.
