--- Comment #16 from DL dredgingthelake@gmail.com 2012-10-23 04:00:30 CDT --- Realistically, I don't think the performance hit for Witcher 2 is necessarily worse than most other games. It's just that this game is so GPU heavy, and most will experience bottlenecks on both the CPU and GPU side.
In particular, you need a very fast CPU to make up for the bottlenecks in the d3d -> opengl conversion.
