I'll be honest, while these details are incredibly impressive in a lot of ways, it isn't worth the sacrifice in frame-rate. Cutting back on smaller details and other subtle bits to improve performance would have been preferred. The fact is, while racing, most of those fine details are virtually invisible and impossible to see especially on rival cars. For replays? Sure, it makes more sense, but while racing it's really not that important.
Thats just like your opinion bro.gif
