Foxsen, the administrator of Lemote BBS, says he has solved 3D driver for Loongson Box after one month work.
ATI didn't provide any proper driver for Loongson Box. I heard that Lemote collected some information and then used a guess-and-try method to write basic driver for R7000 before the Boxes were usable. And now foxsen further finished 3D driver.
However, currently the 3D driver doesn't fully exploit R7000's capacity which gives only 237 FPS on 24bit. Foxsen promised to improve it. Anyway, he' s really a respectable man.
