Far Cry
Our Far Cry benchmark takes a run through the dense Pier level. Geometry instancing (which is the duplication of objects based on a singe model, think replication of blades of grass here, saving lots of unecessary work) helps keep the frame-rate at reasonable levels when in-game options are set to maximum. Again, 1280x1024 was smooth at all but the most complex of scenes. £150 buys you considerable gaming power.
Complex scenes and the additional burden of high AntiAliasing and Anisotropic filtering take their expected toll on midrange 128MB cards, but you would be silly to play Far Cry, set to maximum detail, at 1600x1200 4x AA/8x AF on a GeForce 6600 GT, wouldn't you. Even ATI's RADEON X800 XT PE finds it tough with such load.
