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

The 6600 GT AGP doesn't skip a beat when we move inside Far Cry's volcano. Here it manages to sneak to a small lead over the Radeon 9800 Pro.

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.
