A user by the name of shurik_spb has tweaked out the lighting and colours on 5 of the tracks in F1 2010 to make them look more like real life.  Given that people seem to have quite a few problems with this game, it's great that it seems pretty open to customisation. There are already camera mods but this is the first that tweaks actual content.

Here are some preview shots: 
 

Looks better, perhaps a little too much colour saturation though?

That's kind of what I thought, I think I'm going to wait for later versions to see if it gets tweaked down a little. Apparently you can customise it yourself as well.
