Thanks for the reply > ... but I believe the recommended approach is to start wine after cd to the steam.exe folder I tried, no change in behavior/dump. I agree that the Direct3D/OpenGL error is suspicious. I am not experienced with getting graphics card drivers working, as this is my first computer with a graphics card running linux. However, I installed it using official (not official technicaly, but fedora rpmfusion.org is as good as) repository packages, And have made no changes. From what little i have tested it, e.g. desktop cube using compiz fusion, it seems to be working like clockwork. I did it according to this guide: http://www.mjmwired.net/resources/mjm-fedora-nvidia.html#nvidia_driver_versions and have made no substantial changes since this point. In case it helps, I tried running another game, Civ V.
