Sorry in advance if this is a worn-out topic.
I just installed Max Payne 3 via Steam, and it won't run properly.

I have contacted both Steam and Rockstar, and have gotten zero help

.
In particular, it will only run consistently under Windows Server 2003 SP1 compatibity mode, and then only in DX9 graphics

.
I have Windows 7 Pro 64 bit (kept up to date) and Sapphire HD 7950x2 (driver is current).
I have looked around at various forums and this seems to be a common problem, with many different proposed fixes, few of which make any sense to me (not that that necessarily means anything

); I did try some of them (the less bizarre/adventurous ones. Thank heaven for Windows Restore Points

.) with no result.
I have gotten the Rockstar Social Club stuff working OK, and I can run the game in the compatibility mode mentioned above, but of course i would prefer to run in under DX11. For some reason I do not comprehend, twice I was able to get the game running by selecting Windows 7 compatibility mode and running as admin. The game would start up OK, but when I selected DX 11 graphics setting, the game crashed on restart. I have not been able to consistently reproduce this result -- seems random; most of the time the game will not even start under this compat. mode. It seems to me I have some sort of video driver conflict or incompatibility, but I'm not sure.
AMD says a new Catalyst driver will be out next week, so I am hoping that will fix the problem.
Any ideas ?
How annoying are my Smilies ?
