Some performance observations + graphics settings that have an effect

[Bizly]

Great advice!

I have two 7850s in crossfire... If you are playing on a lower end GPU you might need to reduce the other settings further, however these were the settings I found making the biggest impact on the frame rate. Also if you are suffering from a low performance even on the lowest settings on a decent GPU, the bottleneck is then most likely caused by your CPU.

For me the Catalyst 13.8 beta2 drivers have been working nicely.

I found that if you don't use the beta drivers with the HD 7850 it makes the game unplayable in almost every setting except bare minimum, however with the beta drivers I was easily able to run maximum @ 60 fps with a single 7850.
