For those wondering, my issue (and it seems to be related to all wet tracks actually) is the texture that is from the Lotus foward.. notice that the track looks strange in the foreground..
Its a small section, but its a small section of each wet track- both rain conditions too.
not sure what the story is there... and the drivers were updated the other day.
First, sorry for my bad english.
It's globally the same problem in F1 2011 with skidmarks in wet tracks.
I resolve this with the same solution : edit your hardware_settings_config.xml in C:\Users\Mes Documents\Documents\My Games\FormulaOne2012\hardwaresettings and add this line <track_info_system type="gpu" /> behind <led_display nativeSupport="true" />
This file should look like this :
<?xml version="1.0" encoding="UTF-8" ?>
<hardware_settings_config version="46">
<cpu>
<threadStrategy parallelUpdateRender="true" workerMapFile="system/workerMap4Core.xml" forceFeedbackProcessor="3" dvdStorageProcessor="3" dataSetMonitorProcessor="1" renderProcessor="0" updateProcessor="2" fileStreamProcessor="3" />
</cpu>

<led_display nativeSupport="true" />
<track_info_system type="gpu" />
</hardware_settings_config>
With this file no more graphical bug !
So, bad point for CM for this bug since F1 2010...
