Yes, that may be true. I think the older driver (Xorg 6.7.0) is faster with pci r200. Maybe changes made by Eric Anholt (those connected with r200 lockups, just before Xorg 6.8.0) afected pci performance. I'll investigate this further when I return home. best, -- Jacek Rosik <[EMAIL PROTECTED]> ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
