Dirt Showdown is a video game from Codemasters and is part of the Colin McRae Rally games revolving around a tour of events to compete in allowing you to win money and prizes to spend on new cars and upgrades as well as unlocking new events and races. The game uses high-resolution textures and AA settings to simulate dust particles, terrain and damage to the vehicles.
Dirt gives us a similar performance result to Bioshock when using our standard benchmark settings. The slower frame rates becoming more notable at 1920 x 1080.
As soon as the graphics preset is dropped down to medium, the menus themselves even run a lot more smoothly, granted the image is by no means as clear as it is when running at Ultra settings and 4x MSAA, but it is playable all the same and the individual settings can be tweaked and tuned where necessary to improve things.
