I finally got my computer up and running correctly (a lot due to help from these boards, thanks~!) I was testing it out through a variety of games and I decided to try Lineage 2 with the machine. Much to my chagrin, when I load Lineage2 using the crossfire, I get a lot of graphic errors and sometimes it won't even load, just give me a 'rendering error' message.
Then, just to test, I deactivated Crossfire and it ran fine. I repeated this several times, and found that it cannot run L2 in Crossfire, but easily run it with a single card. What is wrong? Is there a setting I can change, or is it just an incapability with the game?
