...it f*ckin sucks! It's been a long time that I wanted to try it so yesterday I bought a 12$ one month session to finally try the suppose to be good game. Once my gears where setup in place and every button assigned I started my first race in test mode.
After lapping for about 10 minutes here's what I've concluded: The drive is really different from LFS' one, the graphic are a lilttle better but they got a bad optimization so I must turn everything down to get a good framerate (I run LFS at maximum and it's looking perfect).
When I log in on the iRacing website and want to play ... everything seems fine but there's something I don't like, it's kinda too serious, LFS is way more friendly. So that's what I now think of iRacing, do not waste your money on it LFS is perfect (and still a beta), just wait for updates and keep racing. Thanks for reading.
