I'm not sure if Aris can/is allowed to answer this but I'll ask anyway. Is there an environment size limit hardcoded in the engine? Some days ago I was at the WMD forums reading some threads and someone said that pCARS has an environment limitation of 16x16km, so tracks can't be any bigger than that, and so I was wondering about AC and if it has such a limitation, if yes, what would be the size? And then someone may say "Why would a track need to be so big?", well why not?
