System specs are good enough, i5 CPU, 8GB RAM, nVidia GTX 760, yesterdays drivers, Madcadz keyboard and mouse only.
Turbo crashed directly at the start, Steam showed the game running for ~5s and then not anymore, for every start try.
in crashlog only some Stack overflow messages and an Exception,
apparently at Steam overlay Dll.
Turned off Steam Overlay for Turbo, uninstalled nVidia 3D vision stuff (no glasses available anyway),
restarted the PC, nothing works.
Deleted systemconfig file, checked nVidia driver settings (changed most settings to "controlled by application"),
also made sure to try on only 1 screen.
Uninstalled and reinstalled the driver.
Nothing helped.
Really disappointing

One user less, he is refunding the game.
