Let me tell you my story so far.
So, I recently bought this game on steam and played on Windows 7 but with all the stuttering and optimisation issues, I enjoyed it but found I couldn't continue with it, so I changed over to windows 10 to see if it works any better, only to find that now it won't even start, I've re-downloaded it, verified it, but every time I try to run it, it does first-time setup then just flat-out refuses to run, no crash or error message, it just disappears and when I try to run it again it goes back to first time setup.
I've done everything in the pinned post on the steam forum but nothing worked, I've tried verifying, I've looked at my Graphic drivers and they're up to date. Does anyone have any ideas on how I could fix this?
