Dirt Showdown is the latest title in the franchise from Codemasters, based around the famous Colin McRae racing game series, although it no longer uses his name, since he passed away in 2007.
We enabled Ultra image quality settings at 1080p with 8 times anti aliasing, as detailed above.
The system managed to maintain smooth frame rates, although it did drop under 30 frames per second a couple of times. We would suggest lowering the anti aliasing to 4x to improve the minimum frames a little.
