I found odd looking specular reflections at night, and at day during rainy weather. Check this out. For example on realroad surfaces you can easily see specular mask (alpha channel in main diffuse map). Final effect is different on different tracks and depends on specular colour and specular intensity in shader settings but less or more it's visible on all objects in rf2. link1 link2 link3 link4 link5 link6 link7 link8 link9
There are washed because the absence of a direct light? (ie: the sun or target spots), i suposse. Also the sky is black wich is wrong, the sky at night has a light dark blue gradient dome.
