I don't know too much about Open GL but one thing is clear. Obviously what was meant as a standard now is changed by the developpers of cards in very specific ways. To optimise their cards for special computer games. Similar to what Microsoft tries to do with Java and/or html. Make their own "standard" and blame the others. This could be - could be - the case here too. That some companies follow the standards and suffer, others don't and are more successful. I am not saying E-on does it like that but keep that in mind before you shout (not you Mike). It could be that your card driver developer needs to be blamed.
