I am trying some simple patches for: http://bugs.winehq.org/show_bug.cgi?id=24642 and noticed that although glxinfo reports: misha(a)ubuntu:~/.wine/drive_c/Program Files/Tag$ glxinfo | grep -i render direct rendering: Yes OpenGL renderer string: Parallels using NVIDIA GeForce GT 330M OpenGL Engine I get: misha(a)ubuntu:~/.wine/drive_c/Program Files/Tag$ wine Tag.exe err:winediag:X11DRV_WineGL_InitOpenglInfo The Mesa OpenGL driver is using software rendering, most likely your OpenGL drivers haven't been installed correctly fixme:d3d_caps:wined3d_guess_card No card selector available for GL vendor 4 and card vendor 0000. fixme:win:EnumDisplayDevicesW ((null),0,0x32e6f4,0x00000000), stub! and I get different results under Parallels than running directly on the Mac This does not seem to cause a problem for other game demos, such as http://bugs.winehq.org/show_bug.cgi?id=24642, but the message is still there. Any ideas? Thank you Misha p.s. I compiled wine git with: ./configure CPPFLAGS='-I/usr/X11/include' LIBS='-lGL -lGLU' LDFLAGS='-L/usr/X11/lib' make && sudo make install and am using the command: DYLD_FALLBACK_LIBRARY_PATH="/usr/X11/lib:/usr/lib" wine ... on the Mac side. Thank you.
