Switching from AGP 1x to AGP 2x yields an performance improvement of approx. 5%. Switching to AGP 4x (which, according to hardware and Windows specs, should be supported) locks the machine hard. >>>/ Using Xree86 20020829 : >>> >>>* same screen corruption as with stock XFree 4.2 ; >>> >>> > >Can you try again with a 20020906 or later snapshot?

Pity about the screen corruption, though. glxgears -info libGL: XF86DRIGetClientDriverName: 4.0.1 radeon (screen 0) libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/radeon_dri.so libGL: XF86DRIGetClientDriverName: 4.0.1 radeon (screen 0) drmOpenByBusid: busid is PCI:1:0:0 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:1:0:0 disabling TCL support radeonUpdatePageFlipping allow 0 current 0 GL_RENDERER = Mesa DRI Radeon 20020611 AGP 1x x86/MMX/SSE NO-TCL GL_VERSION = 1.2 Mesa 4.0.3 GL_VENDOR = Tungsten Graphics, Inc.
