   Platform Specific Performance Differences With OpenGL ?
  Hi everybody,I'm currently planning to develop a small 2D Game Library, which should be used afterwards for several 2D Games.The main aim of the whole thing is to keep the lib as modular as possible in order to make a great variety of games possible and another important thing is that it should be cross platformed.So the thing that bothers me is, if I should use as well DirectX(or let's say better D3D, because OpenGL is only a graphics lib) and OpenGL, for graphics, so that when running on a Windows Platform DirectX is used and on another platform OpenGL, or is OpenGL as good as DirectX on Windows.For Sound I probably will use OpenAL, or FMOD, or something similar and for Input SDL.To make it short: Are there any disadvantages in using only OpenGL for graphics on all Platforms or aren't there any ???Thanks in advance for your answer.cheers,marcelps: pls don't start a flame war against opengl/directx if you are an directx/opengl fan ;)   
  The performance difference is based on the drivers and cards, not the API.On the high quality cards, there is no significant performance difference.  Somebody with a GeForce or Radeon is going to get high performance on either of them.On the low quality cards, using the built in 4MB integrated chipset, you aren't going to get good performance with either.Just pick the API that best suits your needs and use it.   ;  thanks, all i neededi'm going to use opengl thencheers,marcel   ;  I think you might like to take a look at Photon. Very nice, modern C++ design that uses OpenGL with a 2D focus.http://photon.sourceforge.net/;  thx for the link m8cool stuff
