A short introduction first: in case you didn't know, yes - it is possible to play Motor City Online nowadays. All you need to do is go to GTRCars.net and download update files and launcher.
Now here's my problem: the game worked fine until I decided to update my Win 8.1 to Win 10 Technical Preview. After a short time I had to revert back to Win 8.1, because Nvidia Optimus wasn't working correctly with Win 10. Everything seemed to be fine, all my games were working OK, except for MCO. I can still run it, but the game does not save graphics settings such as car detail level, drawing distance etc. I didn't have such problem before upgrading Windows (but maybe it's just a coincidence and these two facts aren't connected, who knows?).
The game itself runs on a modified NFS High Stakes engine (NFSHS still works flawlessly). All settings are stored within options.ini file, which is located in SaveData folder. I tried changing values in this file manually and then making it read only, but it didn't work for graphics options - the game completely ignores them and still launches with default settings. What's funny, changing other values does affect the game (e. g. launching it in windowed mode).
So, any ideas?
