Early Radeon DRM-Next Tests Ahead Of Linux 4.7, Mesa 11.3: Many Improvements, One Card Falls
With Team Fortress 2 the Radeon HD 6950 was the biggest gainer while the HD 7950 and R7 370 saw small gains in performance and the Radeon R9 290 was again in bad shape with this drm-next-4.7 code.
Unigine Valley was similar to the other tests with three of the graphics cards being in good shape while the Radeon R9 290 fell hard. Nothing in the dmesg, etc, indicated what was going on with these frequent struggles besides only a couple "*ERROR* ci_upload_dpm_level_enable_mask failed."
When running the Xonotic first person shooter game were significant performance improvements for the HD 6950 and HD 7950.
