Trying Out DRM-Next With Radeon/AMDGPU Drivers Ahead Of Linux 4.4
With Tesseract there is a small performance gain to report with the HD 6870.
There isn't much to see out of the Team Fortress 2 results. If the R9 285 Tonga would have worked with this game on the new DRM-Next code, it would have remained slow anyways due to the lack of power management / re-clocking.
Not much to see out of Unigine Valley.
