Hi Martin, So should I assume that you are running fully open-source operating systems, and fully open-source drivers on all your own hardware? :-) > I have e workplace at a customer's location with a PC where I > plugged my own graphics card which serves as temporary FlightGear > testbed, I would love to hear which card/drivers you are using at your customer's location. Are there any rendering bugs? Any odd xserver crashes? What kind of performance are you getting compared to nvidia. If you have found a rock solid, high performance, correctly rendering open-source solution, I'm sure a lot of people would love to hear the specific details. For my day job I manage a research driving sim. We run linux on all our visual channels and are using nvidia hardware/drivers. For this system we can't tolerate driver crashes or rendering errors. This system isn't for play or hobby or expermentation, it is for doing real, paid research so it needs to work all the time. (To be fair, there are many other reasons why it doesn't work all the time, but none of them are video/3d/driver related.) If there is a 3d card with open-source drivers that could perform as well as nvidia in a do-or-die environment, I'd like to hear about it, because to date, I have yet to see anything else that compares.
