Don't really know what we can do. I admit that I didn't check whether Vista was supported before buying the game, mainly because I assume every game coming out nowadays supports it. Someone on the DE forums says they sent in a ticket using a supported system and got a reply saying that they'd look into it.
Plus, they're saying they tried it on a Vista 64 machine and the error isn't even happening. *Shrugs*
We already know for sure that the OS has nothing to do with this issue. People on 32-bit systems are getting the problem and there hasn't been a single post across any of the forums where this is being discussed from someone saying they're
not getting the problem when running widescreen resolutions.
Meridith Braun from DE said that Noviy Disk is working on a patch and that the widescreen problem was included in the fixes (it's in the thread over on the official forums).
I'm fairly certain Asypr's support department is just completely clueless and kept in the dark about what's actually going on. The fact that they replied to person that a 9800 was below the minimum requirements for the game pretty much confirms it.
