Works on my HD3000 now... Not sure we need both checks... either of them will do in my case. The second one might be problematic as some drivers might report a GDI Generic but accelerated device that could run arx... #1 - // Verify that the msaa setting matches what was requested and #2 - // Avoid "GDI Generic" devices...
