When running Warsow and monitoring the system metrics, the CPU usage remained much lower with the open-source driver over Catalyst. This CPU usage difference is perhaps due to a bottleneck in the driver code and needing to wait on the GPU to finish slowly execute its operations. The CPU usage difference was also similar when running Nexuiz.
