Are you using the recent drivers? I also have a radeon5800 series and no problem with black terrain.
I am not having black terrain issues now, but I did when the issue first struck. One of the C2C team made a comment iirc about ATI cards not doing some particular type of processing as well, and it's that I want to know about.
I'm NOT trying to solve a current bug, just asking a question about graphics cards, which will hopefully be seen and answered by whoever it was who posted whatever it was about ATI cards that I vaguely remember but can't find using the forum search facility.
I'm not looking for help with a bug or problem.
Edit: Ah Strategyonly beat me to it. Thanks for clarifying that! The 5850 is going because my husband needs a new PC, if we're going to be spending money on a graphics card I'd rather spend a bit more to upgrade mine (I'm looking at the HD 7970 or GTX 670) and put the 5850 in his new one as I am the heavy duty gamer of the two of us, rather than just buying another 5850 - it's not as if I won't want to upgrade mine at some point anyway so might as well do it now since I have to buy a graphics card anyway! Besides, I've got a tax rebate that wants to be spent on something exciting
