No, in fact, this response is hard to understand. You said GT5 simulates barometric pressure on cars against their poly models, and have yet to provide any proof of such a grand claim...
No one said barometric pressure,at least I didn't,what I mean is that the engine counts with the barometric considerations for the different scripts for the objects or in this case cars,not that it reads the objects according to the shape.
and t.o. that looks pretty good,although I don't posses live I will buy a subscription in the upcoming days(if PSN doesn't go back),then I will add my gamertag,for now I'm playing LFS which is pretty good,and its free so is worth a look,only on PC thought but those Fomulas BMW are quite fun to drive,I hope that FM4 will features some open wheel cars,I know the caparo is included but I want to see a real open wheel like a Formula 3 or something like it.
