siegfriedrox: Nevermind that didn't help on windows. I've tested now.
The best for me is to run the game with -glide (WITHOUT the launcher, reinstalling the game with a clean folder), d3d i just get crashes and in software mode i have those wheels problems, which are fixed more or less with cpu grabber.
Weird thing that it works pretty well on linux (not perfectly, taurus still cannot pass the bridge on the second mission and commits suicide, yet he drives 100 times better than on windows with software rendering).
In summary,
1)try the game normally.
If this doesn't work or you get slow cars:
2)install the launcher (in the right folder), and try software rendering with the cpu grab thing (for me it worked near 80%, it may be different for you).
3) if it still does not work (or you don't want this ugly hack), try glide or d3d from the launcher
4) if it still does not work, uninstall the launcher and the game, uninstall the game (+ clean the folder), reinstall the game, make a shortcut of i76.exe, add "-glide" and try it.
For me 2) and 4) work fine.
Cool, I'm going to try all this out. Been hankering to play some I76, but it's compatibility with windows is a bit lacking...
