Half-Life 2/Counter Strike: Source Hardware Stress Test, Pure Mode
The hardware stress test is definitely not something that reflects any type of gaming process. The only action of the test is flyby through a cavern with water and all over the floor and a number of flying slabs created using pixel shaders. The test should emulate the Half-Life 2 load, but since there are no bots and open terrains, this one only emulates certain portions of the title.
The stress test puts pretty high load on pixel processors, which is why all modern graphics cards except the GeForce 6800 performed nearly equally in 1024x768 resolution achieving about 140fps with the GeForce 6800 Ultra hitting nearly 147fps. In 1280x1024 resolution high-end offerings from ATI and NVIDIA deliver equal results, while in 1600x1200 the RADEON X800 XT takes the lead, but the RADEON X800 PRO stays much behind the competing solutions from NVIDIA.
Generally speaking all graphics cards performed well in the video stress test. Even ATI’s previous-generation mainstream graphics cards perform pretty well in 1024x768. What you should keep in mind when comparing results of the GeForce FX-series to the rest is that they worked in DirectX 8.1 mode with aggressive optimizations of texture filtering, whereas others worked in DirectX 9.0 mode.
