Предыстория:
1. [померяемся] Lightsmark и опенсорсные драйверы (комментарий) (15.01 fps с компизом, 25 - без компиза)
2. +5 fps: sna или плацебо? (29.9 fps без компиза)
Сегодня игрался с мезой и откопал в dmesg вот такую интересную строку:
[drm] MTRR allocation failed.Graphics performance may suffer.
Самый простой способ пофиксить это - прописать в /etc/default/grub
GRUB_CMDLINE_LINUX="enable_mtrr_cleanup mtrr_spare_reg_nr=1"
Вот, что получилось в результате (с компизом и vsync-ом):
