I have a laptop with an Intel 82852/82855 GM/GME integrated video chip.
I know that this is very-low end, but it turns out that the game will run mostly fine as long as I turn down many of the graphic options. (I didn't buy GC2 because it looks pretty. I bought it because of good strategy game-play and AI.)
However, when I first installed and updated, I was presented with a seemingly fatal error about DirectX and true-type fonts. I didn't write down the exact text, but it said that I must update my drivers for GC2 to work (display true-type fonts). There was one OK button. In context, it seemed like OK would exit the dialog so that I could go update my drivers.
But I never bothered to click OK. While the dialog was still open, I went to look for drivers (I keep them updated - there were none newer) and search the forums for answers (found a long post from people that run fine with this video). Then I went on a little rant about a refund (sorry, I was really mad at the time). I forgot about the dialog that was hidden behind other windows.
It turns out that clicking OK launched the game anyway. Yes, there are some graphic glitches, but nothing that prevents me from playing GC2 and nothing that crashes the game. And once the game launched the first time, the DX warning/error never came back. (Btw, I see fonts just fine.)
So, I think it is a bug (or just a design flaw) to present a warning that seems to be fatal. At the very least, my suggestion would be to warn that there MIGHT be problems unless the code can determine for certain that there WILL be problems. Instead of just one "OK" button , perhaps have "Exit" and "Continue Anyway" buttons.
Thanks.
