gf 7600 (медленная отрисовка)

[agita]

приветствую.
заметил при просмотре видео, что движущиеся объекты получаются "порезаны". то же самое при движении окон.
установлен драйвер NVIDIA-Linux-x86-180.29
glxgears ~5000 FPS (стандартный размер)
gtkperf ~10 сек (стандартный размер, все тесты)
compiz тоже работает без проблем.
