For about a year + I've not been able to play, thankfully the above solved the issue [the ati dll file and the resume fix] but not with the current releases.
For me neither of the fixes work using 3.6.12 Inferno release with any of the last 6 ATI drivers [that is as far as I went back in testing different drivers], the game just hangs when trying to access a mission or the tech room[white screen] then I must close it.
I've not tried any of the older Inferno releases other than the last which did not work either for me.
The latest beta however, along with the DLL file and the resume game work around seems to of fixed the problem - "fs2_open_3_6_14_SSE_RC1.exe" - is the beta release that works for me.
I get the feeling the issue is linked to either crossfire and or anti-aliasing, you can tell when the game is going to work as when the "Hints/Tips" dialogue appears in the main screen, a purple horizontal bar comes up [can screen shot this if need be], in my experience that happens in some games when I've set AA up via CCC, in this case it happens either way. The bar vanishes when you close the tips dialogue. When the game isn't going to work, e.g. with the 3.6.12 Inferno's, the bar does not come up at all and going to tech room or mission/hanger hangs the game / white screens it.
With the new CCC drivers they have added application profiles, to make sure it wasn't a crossfire issue i set up a profile for freespace to force crossfire disabled, made no difference.
So for now I'm stuck using the beta, but at least i can play
Just none of the mods i have seem to be compatible with it as they refuse to load.
Not sure if i should of posted this in the relevant thread for the 3.6.14 RC1's, sorry if so. But whatever you guys are doing keep it up pretty please as it makes the game playable again for me and for that, much <3
