The installation of 595 MB was also quite fast, but also rather my good PC applies thank.
Before STEAM must be installed in order to then enable that game online. Everything ran smoothly. What I find, unfortunately pity is that you can find the executable file of the game is very difficult. This path is required ie for my G27 from Logitech, which requires the EXE file in the controller menu. This is a little hidden and indeed with me under the C: drive in Program Files (x86) -> Steam -> SteamApps -> common and here in Spintires folder.
Unfortunately, I do not gamble with the game, because currently no steering wheel, are supported except X-box controller. That's pretty bad and really bad because of the support even on the website clearly said that the steering wheels are supported.
The steering wheel support is probably only with Update 1, how to read and I can hope.
Until then, only play via the keyboard is possible, which does not attract me.
The game runs on a 4.2 GHz and 16GB @ i7-4770k RAM and 4GB GTX770 RAM in the highest resolution with absolute smoothness. The graphics are very nice, but also not a milestone of the genre. Also, the surround sound is birdsong across well.
Unfortunately, I have not brought any single mission to the end, because I'm not perfect right to the control and the manual and the manual and the online help has a way. Nevertheless, I have only myself bogged down and no longer know what to do when the mission simply cancel or disable what frustet.
Maybe I can to the promised steering wheel support nor give one star more, but so far unfortunately only 3 stars from me!
