--- Comment #36 from cruiseoveride cruiseoveride@gmail.com 2010-02-06 14:06:30 --- I hope we haven't forgotten the reason I started this bug ticket, ie. there is a workaround being employed when a combination of VENDOR_ATI and CARD_ATI_RADEON_9500 is used that is required when using the open source drivers.
Whether this is specific to 3dmark2001se or to a HD4870, I don't know. But the "Lobby" demo requires VENDOR_ATI and CARD_ATI_RADEON_9500 to work properly when using open source radeon drivers (see comment #1).
