Dirt: Showdown

Dirt Showdown is the latest in a string of great racing games from Codemasters. Like is predecessor, 2011's Dirt 3, this game sports impressive visuals with DX11 support. “Ultra” settings for shadow effects, global illumination, tessellation, and post processing elements, like depth of field, are available in the game, and in turn, crank up the workload on the graphics subsystem. The game engine also makes use of multi-core processors for higher performance on top-end systems. We tested the game configured with its Ultra graphics options with 4X anti-aliasing enabled at resolutions of 1920x1200 and 2560x1600.

We test Dirt: Showdown with all of its graphics-related options cranked up to their respective maximum values. One feature in particular--Global Illumination, which enhances lighting significantly--runs much faster on the AMD-powered cards. As such, the GeForce GTX 660 card, regardless of their clock speeds, trail every other card in this game, including the Radeon HD 7850.
