My GPU is a Radeon R7 250E. Screen resolution is 3840x2160@60Hz 24bpp. |
| 13 |
|
| 14 |
I had tearing with every player before I used the "TearFree" option |
| 15 |
in my xorg.conf. It contains only a device section, nothing else: |
| 16 |
|
| 17 |
$ cat /etc/X11/xorg.conf |
| 18 |
|
| 19 |
Section "Device" |
| 20 |
Identifier "ATI-Card" |
| 21 |
Driver "radeon" |
| 22 |
Option "TearFree" "on" |
| 23 |
Option "ShadowPrimary" "off" |
| 24 |
EndSection |
| 25 |
|
| 26 |
If you also use a Radeon GPU you can try to enable the TearFree option. |
| 27 |
Since I've enabled this option I have no tearing problems anymore. |
| 28 |
|
| 29 |
If you don't use a Radeon GPU then you should find out if there is a |
| 30 |
similar option for your GPU. |
| 31 |
|
| 32 |
Attached is my Xorg logfile (some non important stuff removed). |
| 33 |
In the logfile you can see that I'm using a kernel parameter "radeon.dpm=1". |
| 34 |
Without this parameter I had performance problems with my GPU in the past. |
| 35 |
To be honest, I don't know if the performance problem I encountered still |
| 36 |
exist without this parameter. Maybe it has been fixed in the meantime. |
| 37 |
|
| 38 |
BTW: I'm using x11-base/xorg-server-1.18.4 and |
| 39 |
x11-drivers/xf86-video-ati-7.7.1. |

I don't think that it is important but for the sake of completeness |
| 54 |
these are the USE flags for mpv (0.9.2-r1) on my system: |
