--- Comment #1 from Armin K krejzi@email.com --- Correction: DPM does seen to work, as indicated in performance increase in Talos Principle (17 FPS on 4.8 to 44 FPS on 4.9), but the rendering is broken.
Still, message about VI performance levels is a bit confusing. I assume HP's atombios has different perf levels. It would be nice if that would be fixed.
