3D для R600/R700

Внуки твои вероятно дождутся...

Дождёшься, конечно. Вопрос лишь - проживёт ли так долго твоя карта? Железо ведь тоже не вечное, ну лет 10 протянет, а там...

пробовать/не пробовать..

работает только с radeonhd драйвером

glxgears - http://img7.imageshack.us/my.php?image=glxgears.png

ну, теперь соталось два шага сделать - порт в унифицированный radeon-rewrite (менеджер памяти) и порт в Gallium3D (наше светлое будущее без софтовых откатов, ой software fallback)

года два, может меньше. Nouveau по крайней мере прошёл путь от "колесиков" до OpenArena за это время. Спасибо смелым экспериментаторам, удачного вам баг-хантинга! (я пока свою rv280 менять не собираюсь, впрочем и для неё в багзилле всегда пара строчек найдётся)

*осталось (что за пальцы впереди паровоза, т.е. головы ... мои извинения)
