You can provide a similar behavior with opengl: from http://rzaix12.rrz.uni-hamburg.de/doc_link/en_US/a_doc_lib/libs/openglrf/glXGetFBConfigAttrib.htm <snip> GLX_CONFIG_CAVEAT This attribute defines any problems that the GLX FBConfig may have: GLX_NONE No caveats GLX_SLOW_CONFIG A drawable with this configuration may run at reduced performance. GLX_NON_CONFORMANT_CONFIG A drawable with this configuration will not pass the required OpenGL conformance tests. <snip> as example you can see wglGetPixelFormatAttribivARB implementation in dlls/opengl/wgl_ext.c :) But you must test what windows provide and on which configs Regards, Raphael
