I could not figure out which options settings were controlled by which .ini file, so I copied the entire AC/System folder as a backup. However, I don't think I'll be using it, because when I went in to play, I took the time to truly experiment with every setting the game has to offer and found what I think is a better set of options for me and my wheel than what I had before.
While that is obviously great news, I'd be willing to bet you could do even better by messing with some of those ini files. Graphics can be improved quite a bit my messing with ini files as well.
What is the actual release date for those not getting in on early access, and what is FMOD?
No one knows release date. If I had to guess I'd say mid to late November. They were shooting for end of October, but I think the RC has more bugs than they anticipated.
FMOD is the new audio engine they implemented for 1.0 Gives the devs (and modders) better tools & effects for audio production.
I noticed that the 5.1 surround is noticably better than it ever has been. I really wish it had adjustments for each speaker's volume, though. Maybe one of my other apps will give me that ability.
There were some bugs with 5.1 surround after FMOD implementation that I believe they're still ironing out. I'm sure you know this but for those that don't you can adjust some volume levels in the (in game) audio options for better balance. IIRC you can adjust engine, tire, wind, brakes, road noise all independently.
Happy to hear you're enjoying the game more now.
PS... I have an Evo I'm working on.
