Iv just recently started using OpenTK to substitue XNA in my cross platform 2D Game engine. firstly, i was amazed how easy it was to use so thanks for that.
But i would like to make a suggestion for the main game loop and the paremeter passed to the Update and Render methods on the GameWindow class. Currently in update the UpdateFrameEventArgs is passed in which contains a double Time value which is the number of seconds passed since last update. I think a nice addition would be to model the XNA time class and offer ElapsedGameTime and ElapsedRealTime values on the UpdateFrameEventArgs parameter. These would both be TimeSpan's.
I would be willing to try make this mod myself and offer the solution for commit. But before i do has anyone else already done this, or does anyone have any different suggestions, would this change get commited if i was to implement it ?
