Windows Vista/7 resolution problems (800x600 bug)

[Edorf74]

I had this strange thing happening. I recently upgraded the ram on one of my laptops that was running STW Gold Edition. Upgraded from 4gb to 8gb, running
64-bit win 7 and an Ati card.

Until then I have used the msconfig memory fix to reduce system mem. When I started STW today with all the 8gb in system I could suddenly run the game in 1024x768 res.
I was really wondering what did this. I came to the conclusion that it was not any newly installed drivers that made this happen.
Went into msconfig again and reduced the ram to 4gb to check if the situation would be the same. Started the game and it could not run in 800x600.

So I have this: I actually got the resolution problem fixed by upgrading the ram to 8gb. The solution also applied to Medieval Total War that had the same issue.
