Summary: [r300g] Driver needs some kind of force_s3tc_enable option Product: Mesa Version: git Platform: All OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: rankincj@googlemail.com
Some games (such as World of Warcraft) need S3TC texture support, and so will crash if the OpenGL S3TC extensions are not advertised. Currently, the only way to make Gallium advertise the S3TC extensions is to load the IP-encumbered libtxc_dxtn library.
WoW can run successfully using the r300c driver without the libtxc_dxtn, provided the force_s3tc_enable option is used. (There are some issues with corrupt textures, although some of these issues might be caused e.g. by r300c not supporting texture cache regions. However, my point is that WoW doesn't crash instantly with a null pointer exception if the S3TC extensions are available.)
