WARNING: SCREENSHOTS ARE FROM NEAR END OF CHAPTER 1.

Running The Witcher 2 with everything maxed, including AA and Ubersampling.

GPUs: 3xRadeon HD 5850 Black Edition in CrossFireX.

AMD driver package version 8.85.6-110524a1-119714E
Using 11.5 CAP2

I've got the same thing, as does every other Crossfire user who installed the hotfix.

Hopefully either the 1.1 patch or the CAP3 fixes it...

So unfortunate. The game finally runs perfectly, never dropping below 60FPS... but there are giant light beams everywhere. I have seen it in a number of places now into Chapter 2.

Yeah oh well, hopefully it will get fixed in the coming weeks.

You can of course disable Catalyst AI and loose Crossfire support to get rid of it.

For now you get to choose the lesser of two evils.
