Even with succeeding updates we still found the R9 290 Linux performance to be poor -- and that's for the high-performance Catalyst driver over the open-source RadeonSI Gallium3D-based driver. In this article are fresh benchmarks of the high-end NVIDIA GeForce and AMD Radeon graphics cards from Ubuntu Linux using the latest beta graphics drivers.
