Now with : - xserver 1.7.4 - 2.6.33rc7 with KMS - libdrm, mesa, xf86-video-ati from git 2D and 3D are back OK on an R700 (HD4650 mobility (M98))
However I see 2 performance issues : - glxgears tops at 1450fps (compared to ~2500fps without KMS) - GL vsync is broken, ie visual tearing especially at playing large videos (XV or OGL) with Kwin compositing enabled Any thoughts on this ? > On Sat, 30 Jan 2010 15:35:44 +0100 (CET) > "Damien Mir" <[email protected]> wrote: > >> Hi, >> >> I just tried KMS with "radeon" driver, and 2D seems notably slow. >> Widgets takes time to draw, scrolling in Dolphin or Firefox lags, as >> if some 2D acceleration was not working alright. > > I use radeon KMS on an R600 (HD 3870) and all works really well. 2D as > well as 3D (glxgear, tuxracer, nexuiz).
