The problem exists on both gnome-session and Raw X. It works well on HSW/BYT-M. It’s Xserve regression. As I known, the good commit is git-264fc3a. It can’t be bisected because errors with “Fatal server error:”. Performance status -------------------------------------------------------------------- Test on IVB git-2ea973e git-264fc3a padman, 158.1fps 184.6fps smokin-guns, 136.4fps 152.5fps urbanterror, 110.7fps 120fps Reproduce steps: --------------------------------------------- 1. xinit& 2. vblank_mode=0 ./smokinguns.x86_64 +set r_fullscreen 1 +timedemo 1 +set demodone "quit" +set demoloop1 "demo pts; set nextdemo vstr demodone" +vstr demoloop1 +set r_customwidth 1920 +set r_customheight 1080
The problem also exists on HSW/BYT.
I don't see any significant difference between 1.14.5 and 1.15.99.900 on ivb i7-3720qm. Let's start with Xorg.0.log from both versions and see if there are any significant feature differences.
