I don't think so. The "radeon" OSS drivers allow for basic 3D (yes, quite suboptimal, but enough for my purposes) The wiki says that for the ATI 9200 the "radeon" driver should allow a good composite experience: "You can get hardware accelled Render (EXA) for 9200 and below, using X.org 7.0 driver 'radeon', thus making Composite ridiculously fast and even overcome NVidia cards, since they don't support EXA yet." In fact, once tweaking xorg.conf for performance, composite works fast and quite well, apart from the occasional xorg CPU problem of my original mail. It seems more like a bug, however. > My experiences were that composite with the radeon driver were ... poor I guess it depends from your card. ATI cards below 9200 are much better supported by "radeon" than newer cards. Until I can, I would prefer to stick with the OSS drivers. m. -- gentoo-user@gentoo.org mailing list
