Testing 4.6 DRM/i915 from cftdisk_2016053119.img on rMBP 13=E2=80=9D = Late 2013. This is a Core i5 Haswell 4288U with Intel Iris 5100.=20 In principle built-in Retina screen, HDMI and mDP are working = simultaneously. FPS of 3D accelerated demos such as Teapot fluctuate = wildly and exhibit significant stutter. Might the issue be temperature = throttling related? Unfortunately the disk image from 31-May-2016 20:18 does not include = XFCE or KDE4. Joeuser=E2=80=99s xinit refers to a file that does not = exist. I will set up a more complete testing environment as time permits and = investigate the performance issue further. Many thanks to mmacy and everyone else for their contributions towards = the updated graphics stack on FreeBSD.=
