I have recently noticed that at the start of races other drivers have square wheels and its starting to get annoying. There must be a setting to stop this but i can't seem to find it. Can anyone help?

cheers in advance

this is the dinamic detail reduction, or something like that, here is a pic of it(not very good one but will do the work :P).
By put less of "that" :P, it will be less radical in the dinamuic reductions, but you will get a down in FPS
Sry for the bad english, hope it was usefull.

cheers
