--- Comment #3 from Henri Verbeet hverbeet@gmail.com 2011-03-09 06:46:42 PST --- You need at least --enable-gallium-r600, an can just use --with-dri-drivers="". Note that you need to build a 32-bit driver for Wine. With WINEDEBUG="+wgl" the first couple of lines ("GL renderer") should mention Gallium.
