We included DiRT 2 as a DirectX 11 benchmark. Unfortunately, DirectX 11 is irrelevant here because all of the enhanced effects are pre-empted by the medium detail setting. This setting was required to get playable performance from the low-end Radeon HD 5450. So while enabling the newer shader model doesn't cause a performance hit, it doesn't really offer any enhanced DirectX 11 effects, either. Crowds and water effects are turned off at the medium setting, two of the main areas that receive tessellation enhancements from DirectX 11 mode.
Even with the effects turned down to medium, the Radeon HD 5450 is barely playable. Once again, the Radeon HD 4650 puts the similarly-priced competition to shame.
