Problem Description:
CrossFire not working in NWN2 at all.

Yes, I have CrossFire
Yes, I have CrossFire enabled and working from the Catalyst Control Center.
Yes, I've verified CrossFire working in the 3dMark and Vantage Benchmarks.

No, CrossFire is not being used by NWN2 at all. The game works, like it always has using only one GPU.
NWN2 lists it as SLI/Crossfire compatible.
I can confirm by performance, GPU usage readings, and tempurature of the two video cards.
The first video card is being used 100%, the second 0% idle and cool.

CrossFire is a pretty common set up these days, so I'm sure someone has it working somewhere.
Websearches have only found very very old info.

Thank you ahead of time. I hope we can get a real solution and share it with the community.
