Proprietary vs. Linux Git, Mesa 11.2-devel, DRI3 For R600g/RadeonSI
With Metro 2033 Redux and Metro Last Light Redux, the performance was significantly lower on the open-source driver than with Catalyst in this latest round of testing. Additionally, the R7 370 and HD 7950 cards were experiencing stability issues with the current driver used.
Under OpenArena was another game where the Radeon HD 7950 continued to be unstable and would end up losing its display. While the HD 6870 performance was quite close on the R600g driver, the R9 290 results show there is still much more potential to be squeezed out of the RadeonSI Gallium3D driver.
