Ребят помогите пожалуйста... у меня видео карта довольно новая Radeon 3870x2 512 мб...

Да ты уже не первый с этой картой . Возможно связано с тем, что 2-ядра .
Поробуй проверить температурный режим . У меня одиночная такая карта ( 3870), так я принудительно выставлял в Riva Tuner обороты кулера, а то до этого перегревалась . У последних Атишных карт у многих проблема перегрева .

Может быть мощности БП или охлаждения не хватает? У тебя карточка весьма горячая и прожорливая...

Тебе надо исправить CCC.Если при установке была ошибка (Установить flamework 2.0),то качай эту фигню и переустанавливай дрова.

Жди пока дрова поправят, потрись на форумах может что нароешь. Покупая карточку от ATI надо было иметь это в виду, а если хочешь заценвать сразу, брал бы тогда уж NVidia

Даа.. Карточка довольно мощная. Может действительно прав Витя Семенов насчет flamework 2.0?
Припоминаю и у меня были траблы с этим фреймворком. Драйвера без него корректно не становились. Так я сгоряча и третью версию скачал и установил.
Полет нормальный.

Как вариант позыркать Radeon.ru
