We are thinking about requiring OpenGL 3.3 in a future version of Doomsday. As time goes on, OpenGL is evolving and Doomsday's reliance on the OpenGL 2.1 Compatibility profile is becoming more and more of a hindrance — OpenGL drivers usually have better support for the up-to-date versions of the API.
That is why I'm putting up this poll: Does your gaming machine support OpenGL 3.3?
An easy way to check this is to launch Doomsday and open the log history. There will be a message like this near the start:
OpenGL X.Y supported
