No not really RampantAndroid.
Simply because:
1) Far Cry's screenshots taken from the game with the F12 key are automatically created as .JPG's.
2) I do not have them as originally created from the game in .BMP's, of course.
3) Changing format from .JPG to .BMP wouldn't have the same quality as in automatically creating them as .BMP's in the first place.
4) I believe I've made my point, which is clear enough with the posted .JPG's: HDR, in Far Cry at least, is affected by Adaptive A-A, as ATi tells it is capable of. The X1K series is technically, physically capable of that. Now another question that could be asked is ... are developers ready to make their games optimized for that ? I'm not sure. I cannot say.
Personally, I didn't buy an X1800 XL just because it's ATi, or just because Ruby is drawn on the cooling solution of the card, but because I had a superb deal for it, that only a fool with the money for that kind of products would have refused to grab the opportunity.
And now as I use it regularly I discover a great Graphics card, that I myself can admit did avoid getting information from, since I wasn't interested, by you know what ? By mere sayings, and forums posts.
Now all I can do, and say, is to eat my thoughts back, and be proud I have such a great card at the price I got it.
