AMD have been promising a huge driver update for a little while now, and before we receive this new wonder driver, AMD have released the Catalyst 13.8 Beta drivers.
The new AMD Catalyst 13.8 Beta drivers fix the frame latency issues that are apparent on Graphics CoreNext (GCN) GPUs, meaning micro-stuttering issues with CrossFire configurations should see some big improvements. The driver also includes a fix that ensures frames generated by member GPUs of a CrossFire configuration are displayed in an even and regular pace.
AMD have also provided full support for the OpenGL 4.3 API in the latest Catalyst 13.8 Beta drivers. Once you've downloaded them, you can create application profiles within Catalyst Control Center for OpenGL applications, with CAP updates now pushed out for such apps.
