EDIT: i dont know how but this solved my issue. rename libgcc_s.so.1 from /home/username/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu

folks say there is a performance hit in latest foss amd driver. and there are people working this out somehow. –  c.k. Jul 3 at 21:27

Don't listen to steam. Make sure you have direct rendering by checking glxinfo | grep "direct rendering". If that says No, you have a problem then.

it says yes. but the error poppes out everytime i launch steam. when i try to start a game from the library another opengl error comes out. –  c.k. Jul 3 at 21:29
    
Try and restart steam. If the error persists, it's probably because steam checks for vendor and renderer string. –  dekomote Jul 3 at 21:31
    
restarting didnt help. i added the second error message. –  c.k. Jul 3 at 21:34
    
Now do glxinfo | grep OpenGL and paste the output. –  dekomote Jul 3 at 21:40
    
Everything seems in order here. If you can launch games, you will have to deal with the errors somehow. If not, try to install the 32bit mesa and dri –  dekomote Jul 3 at 21:45
