With R600g Now Supporting OpenGL 4.1, See How The Open-Source Performance Compares To AMD Catalyst

With those Steam Linux games now out of the way, onto some of our classic OpenGL Linux tests.

R600g Radeon vs. Catalyst Linux Testing

The Tesseract open-source first person shooter was running the same speed between the two drivers on both graphics cards!

With the Xonotic first person shooter, both HD 6000 series graphics cards were yielding frame rates of ~80% the count of Catalyst.

Overall, these are some of the best results we've seen out of the open-source R600g Linux driver stack. In some games, the performance of this open-source driver stack with DRI3 enabled is hitting -- or even exceeding -- the Catalyst frame-rates. It's perfect timing with AMD working to remove support for pre-GCN hardware from Radeon Software Crimson. The only sad part of these results is that pre-GCN hardware outside of the Cayman and Cypress series are still left at OpenGL 3.3 support for the time being, thus not making this open-source driver suitable for running many of today's modern Steam Linux game titles.

With the year quickly coming to an end, I'm also working on some latest open-source driver figures for the RadeonSI Gallium3D driver, some year-over-year comparisons, and more.
