Процессор при этом нагружен на 35-45%, причём — все четыре ядра! Это называется софтверным ускорением. :))

Включаем аппаратное 3D-ускорение на Radeon HD

1) Добавляем строчку игнорирования NOUVEAU, чтобы он не мешал графическому окружению:
% echo 'WITHOUT_NOUVEAU=true' >> /etc/make.conf


2) Пересобираем graphics/libdrm, graphics/libGL*, graphics/libglut:
% portupgrade -fp graphics/libdrm && portupgrade -fp graphics/libGL && portupgrade -fp graphics/libGLU && portupgrade -fp graphics/libglut graphics/mesa-demos
или, если есть время, так:
% portupgrade -fpr graphics/libdrm


3) Перезагружаемся и смотрим на результат:
