Around 45 fps in both cases here. > and 5 fps in full screen saved mode. There seems to be a bug in the current DRI code which prevents direct rendering under certain circumstances, in particular this one. It's hard to track down, it fails to map the framebuffer - no idea what's up yet. > foo:~%env LIBGL_DEBUG=verbose glxgears > libGL: XF86DRIGetClientDriverName: 4.0.1 radeon (screen 0) > libGL: OpenDriver: trying /usr/X11R6/lib/modules-dri-trunk/dri/radeon_dri.so > libGL: OpenDriver: trying /usr/X11R6/lib/modules-dri-trunk/dri/radeon_dri.so > drmOpenByBusid: busid is PCI:1:5:0 > drmOpenDevice: minor is 0 > drmOpenDevice: node name is /dev/dri/card0 > drmOpenDevice: open result is 4, (OK) > drmOpenByBusid: drmOpenMinor returns 4 > drmOpenByBusid: drmGetBusid reports PCI:1:5:0 Looks good, hmm. I have a similar problem when running with PCI GART on this PowerBook, but that can't be the case for you because it's still disabled on x86. I assume it's related to the L3 cache here, maybe something about AGP for you... For the record, can you try if setting any of RADEON_NO_CODEGEN=t RADEON_NO_VTXFMT=t RADEON_NO_TCL=t makes a difference? -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
