Far Cry - Volcano
Like our Doom 3 "heat haze" demo, the Volcano level in Far Cry includes lots of pixel shader warping and shimmering.

For some reason, the X700 XT stutters through the volcano demo at 1024x768, but not at higher resolutions. I double and triple-checked the results, running through the demo a total of nine times, but the X700 XT's scores were consistently within a few frames per second.
