        <pre>Hi! 

I'm experiencing a problem where I haven't been able to run my
games/videos as I used to do on my intel graphics card. I don't know
what happened, it really just suddenly started going slow, I notice
this while playing videos using mpv over vdpau, playing left4dead2
over steam and even on chromium scrolling. So far I've tried the
following:

* Using "AccelMethod" "glamor" / "sna" on xorg.conf.d
* Resetting my bios settings to the default config.
* Enabling/disabling, as suggested by the wiki[1], on
modprobe.d/i915.conf: options i915 i915_enable_rc6=7 i915_enable_fbc=1
lvds_downclock=1

A little of extra info:

* I tried to watch the contents of
/sys/class/drm/card0/gt_cur_freq_mhz but it is always somewhere
between 300-500-700 it never reaches 1050 which is supposed to be the
max freq that my card allows, but not sure how it was before it got
slow.
* I'm running qtile as window manager which is a tiling wm with no
compositing, along with it I run kdeinit4, gnome-settings-daemon and
pulse to have a modern desktop.
* I close my browser when I run the game/video and vice versa.
* htop doesn't seem to be showing weird processes running at the same time
* On systemd only cups and networkmanager are enabled
* Before the slow occurred I tried running gmabooster[2] ant it
segfaulted, not sure if this could be the problem because gmabooster
changes are not supposed to be permanent, I have rebooted my laptop
several times after this.
* This is the result of $ lspci |grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core
processor Graphics Controller (rev 09)
* I'm using archlinux with: linux kernel 3.13.7, libva 1.3.0,
libva-intel-driver 1.3.0, libva-vdpau-driver 0.7.4, xf86-video-intel 2.99.911

I really don't know what else to do, so if any of you guys have a
recommendation or suggestion it will be very welcome.

Thanks
