As far as I know ATI Radeon X1300 is first ATI graphic card which has full hardware support for OpenGL 2.0.
Version 1.20 shading language is specific to OpenGL 2.1 so you should state that minimum OpenGL version for your game is OpenGL 2.1.
@AirPas
Are you using AMD/ATI based drivers or ones that are shipped with Windows XP. Based on my expirience the ones that are shipped with windows XP does not provide full capability of ATI based graphic cards.
So I strongly recomend downloading and instaling newest drivers from AMD website. You could even use their driver autodetection software that you can get here: http://support.amd.com/us/gpudownloa...to_detect.aspx
